Contraception Flashcards
What effect does CHC have on serum estradiol levels and serum FSH and LH
CHC provides synthetic estrogens which are not detected on conventional estradiol serum assays
CHC suppresses the hypothalamic-pituitary axis and therefore levels of FSH and LH are low
Cautions to using Ulipristal acetate (EllaOne®) as emergency contraceptioon
Avoid in uncontrolled severe asthma
Avoid severe hepatic impairment
other factors may effect drug efficacy - including taking enzyme inducing drugs eg phenytoin or rifampicin.
advice for emergency contraception for a patient on enxyme inducing drugs
Ideally a Cu-IUD should be offered if suitable.
If Cu-IUD is declined or not an option
then offer double dose levonorgestrel - within 72 hours
what type of drug is Levonorgestrel?
Emergency contraception
Synthetic progesterone
1.5mg single dose as soon as possible after sexual intercourse, licensed up to 72 hours after SI.
advice if vomiting within 2 hours of taking levonorgestrel
If vomiting within 2 hours repeat dose can be given
above what BMI should double dose levonorgestrel be offered?
BMI 25 +
what type of drug is Ulipristal (EllaOne®)
Emergency contraceptive
Selective progesterone receptor modulator
30mg single dose
Effective up to 5 days after sexual intercourse
after ulipristal accetate vomiting within what timeframe would mean it is recommended for a repeat dose to be offered
Vomiting within 3 hours of ulipristal accetate should be offered a repeat dose
Can contraception affect the timing or duration of menopause?
Contraception does not affect the timing or duration of menopause
May mask the symptoms
Some women hesitant to use contraception that will conceal indicators of this transition.

Why is use of CHC rated higher risk on the UKMEC for women with:
- a BMI ≥ 35
A raised BMI over 30 increases VTE risk
This increases substantially more with BMI >35
Why is use of CHC rated higher risk on the UKMEC for women :
- who smoke and are aged ≥ 35
smokers using the CHC have an increased risk of CVD especially MI
The increase in risk is related to the number smoked per day
From the age of 35 onwards an excess in mortality becomes apparent
What are some risk factors for VTE post-partum

- SLE - no antiphospholipid antibodies
IMP / DMPA / POP = 2
CHC = 2 - SLE - positive antiphospholipid antibodies
IMP / DMPA / POP = 2
CHC = 4
UKMEC for IUD /IUS with history of
- SLE - no antiphospholipid antibodies
- SLE - positive antiphospholipid antibodies
UKMEC for IUD /IUS with history of
- SLE - no antiphospholipid antibodies
IUD = 1 IUS =2 - SLE - positive antiphospholipid antibodies
IUD = 1 IUS =2
why is the UKMEC for women with SLE using hormonal contraception a 2?
(4 for CHC with antiphosopholipid antibodies)
Women with SLE are at increased risk of ischaemic heart disease, stroke and VTE - therefore score reflects this.
No evidence that the use or hormones including CHC causes a disease flare
Advice re progestogen only contraception and breastfeeding
no harmful effect of POC on breastfeeding performance.
No harmful effects on infant growth, health or development
What consideration should be made regarding the use of oral contraception in women who have undergone bariatric surgical procedures?
If the surgery involved a malabsorbtive component then absorbtion of the POP / COCP may be reduced.
Also consider decreased efficacy if long term side effects of vomiting or diarrhoea

Postpartum sepsis
Non-contraceptive benefits of COCP
50% reduction in ovarian and endometrial cancer Improved acne Reduced HMB Alleviation of dysmenorrhea Treatment of hirsuitism caused by PCOS Treatment of PMS Reduced risk of colorectal cancer
Mechanism by which COCPs reduce dysmenorrhea
Inhibit ovulation
Reduce prostaglandin concentrations
Secondary causes of dysmenorrhoea may also respond to COCPs e.g. Endometriosis, adenomyosis, fibroids
Continuous COCP regimen may further improve menstrual pain scores
Does use of COCPs influence the development of fibroids
No evidence of influence on size or number of fibroids
What is the mechanism by which COCPs decrease acne?
Decrease free testosterone levels in the serum
By inhibiting LH stimulation of ovarian androgens
And increasing SHBG levels
And inhibiting 5-alpha reductive activity = converts testosterone to diydrotestosterone in hair follicles and skin
Over what weight is the CTP less effective
> 90 kg
Most commonly used estrogen in CHC
majority COC and CTP / CVR contain 20 μg to 35 μg synthetic estrogen ethinyl-estradiol.
A mestranol COC exists = metabolised to EE
(50 μg mestranol ~35 μg EE)
COC exists contain. I got 17β-estradiol = theoretically improved safety profile - less thrombogenic
What are First generation progestogens
First: norethisterone (NET)
What are second generation progestogens
Second: levonorgestrel (LNG)
What are third generation progestogens
Third: desogestrel, gestodene, norgestimate
What are the newer (4th) generation progestogens
Newer/other: drospirenone (DRSP), dienogest, nomegestrol acetate
What does Co-cyprindiol contain?
Co-cyprindiol = 35 μg EE with cyproterone acetate = an anti-androgen
Indication for Co-cyprindiol (cyproterone acetate + EE)
for management of moderate / severe acne + hirsutism.
Women using co-cyprindiol for these indications do not require additional contraception.
What does the combined patch contain?
CTP releases average 33.9 μg EE
and 203 μg norelgestromin per 24 hours
What is norelgestromin a metabolite of?
norgestimate
What is etonogestrel a metabolite of?
etonogestrel is the active metabolite of desogestrel
What hormones are in the combined vaginal ring?
CVR releases EE 15 μg and etonogestrel 120 μg daily
What is the traditional COCP regimen?
Traditional (standard) COCP regimen
21/7 cycle - designed to induce a bleed each month and mimic naturally occurring menstrual cycle
Drawbacks to the HFI of the traditional CHC regimen?
► Withdrawal bleeding may be heavy, painful or unwanted.
► HFI may be associated with symptoms - headache, mood change
► Ovarian suppression is reduced and follicular development occurs during the HFI, particularly with COC containing lower EE doses = Errors around HFI could risk ovulation and potential pregnancy
What are the tailored CHC regimens?
Tailored CHC regimens include:
► Continuous use of CHC = no HFI
► Extended use of CHC = less frequent HFI -timing of HFI can be fixed or flexible
► CHC regimens in which the HFI is shortened
► Extende use with a shortened HFI
Benefits of a continuous or extended CHC regimen?
CHC is taken for >21 consecutive days without HFI
Eliminate / reduce frequency of withdrawal bleeding
Fewer HFI associated symptoms
Bleeding can be scheduled
Reduced risk of escape ovulation = potentially reduced contraceptive failure
Less risk of forgetting to restart on time if breaks occur less often
Risks / downsides of a continuous or extended CHC regimen?
Breakthrough bleeding
Irregular spotting
Will use packs of pills more quickly than the dates dispensed
Describe Flexible extended use of the CHC
Continuous use (≥21 days) of active pills/patches/ rings until breakthrough bleeding occurs for 3–4 days Then 4/7 HFI and resume
Bleeding patterns with extended CHC regimens
In most studies bleeding patterns with extended CHC
regimens were
equivalent or improved
Overall total number bleeding days is lower with continuous or extended regimens
BUT increased BTB in 1st 3 months continuous / extended - then decreased with time
Advice for starting CHC if there is a pregnancy risk within the last 21 days
Do a high sensitivity urine pregnancy test - if negative QuickStart CHC
Regarding pregnancy risk from last 21 days - arrange follow up high sensitivity UPT at 21 days after last UPSI
E/P 7/7
Advice for starting CHC for women with a short menstrual cycle
<5% F 15–44 years
<2% F 20–39 years have menstrual cycles <20/7
=Concern re earlier ovulation - advise EP for 7/7 when starting CHC if short or variable cycles
FSRH advice for being ‘reasonably certain’ a F is not pregnant
Any 1 or more of the following criteria are met AND no symptoms / signs of pregnancy:
► no intercourse since start of LMP, childbirth, abortion, miscarriage, ectopic pregnancy or evacuation for GTD
► Correctly and consistent use of reliable contraception. (barrier methods can be considered reliable providing used consistently and correctly every episode)
► Within 1st 5 days of onset LMP
► <21 days postpartum
► Fully breastfeeding, amenorrhoeic and less than 6 months postpartum
► Within 1st 5 days after abortion, miscarriage, ectopic pregnancy or evac for GTD
► LSI >21 days ago and negative high-sensitivity UPT
Advice re starting CHC after levonorgestrel EHC
QuickStart CHC immediately
Arrange HS UPT in 21/7
Advice re starting CHC after ulipristal acetate EHC
After UPA-EC
Wait 5 days before starting CHC then use EP for 7/7
Total EP is therefore 12/7
Advice re switching from traditional POP to a CHC
Ensure POP used correctly - consider EHC if any risk
Switch immediately to CHC
EP for 7/7
Primary MOA of traditional POP is NOT inhibition of ovulation - hence EP req in case ovulation occurs before CHC efficacy established
Advice re switching from an anovulatory Progestogen only method to CHC
► Desogestrel-only pill
► Injectable
► Implant (within licensed duration)
Ensure correct use and consider EHC if not
Start when next desogestrel POP due
Start any time up to when repeat injection is due
Start any time up to when the implant is due for removal
NO EP required - MOA is inhibit ovulation = CHC suppresses ovulation by time the inhibitory effect of prev method lost
Advice re switching from LNG-IUS to CHC
If LNG-IUS within licensed duration of us - start CHC at any time
EP or retain IUS for 7/7
If UPSI in last 7/7 retain IUS 7/7
(or EHC and arrange UPT in 21/7 - less advisable)
Advice re switching from Cu-IUD to CHC
Up to Day 5 of menstrual cycle - start CHC immediately and can remove Cu-IUD at same time with no EP
At any other time during the menstrual cycle - start CHC and use EP for 7/7 or retain IUD for 7/7
If UPSI in last 7/7 retain IUD 7/7
(or EHC and arrange UPT in 21/7 - less advisable)
What factors may reduce the contraceptive effectiveness of CHC?
Weight >90kg with patch use
malabsorptive and restrictive bariatric procedures
enzyme-inducing drugs
Vomiting and diarrhoea
Within 5/7 of taking UPA-EC - decreases efficacy of UPA
CHC taken with lamotrigine reduces serum lamotrigine levels
Definition of missed COCP
COC pill is missed if it is not taken in the 24 hours after it should have been taken
Advice re missed COCPs in weeks adjacent to the HFI
Risk of ovulation if the HFI is extended
Missing pills in wk 1 or wk before HFI effectively extends the HFI
≥72 hours since last pill in current pack was taken
In wk 1 - offer EC if UPSI - most recent missed pill ASAP and remaining pills at usual time with E/P 7/7 + UPT 21/7
Wk before HFI - omit HFI - most recent missed pill ASAP, remaining at usual time, E/P for 7/7
Advice re Missed COCP in weeks not adjacent to the HFI
Ovarian activity is suppressed after 7 consecutive days COCP
Missing 1 -4 consecutive pills on days not adjacent to HFI results in little follicular activity = low risk of ovulation.
NO EC required
NO EP
Take missed pill immediately then resume at usual time
Advice re Unscheduled patch detachment for <48 hours or continued use of same patch for up to 48 additional hours
Week 1 after HFI - Attach new patch ASAP, Keep new patch on until scheduled removal day - No EP, No EC
Weeks 2 or 3 after HFI - Attach new patch ASAP, Keep new patch on until scheduled removal day - No EP, No EC
Advice re unscheduled patch detachment for ≥48 hours or continued use of the same patch for ≥48 additional hours
Wk 1 after HFI - Consider EC if UPSI during HFI or wk 1
Attach new patch ASAP - keep new patch until scheduled removal day, EP for 7/7, UPT in 21/7
Weeks 2 or 3 after HFI - EC not required - Attach new patch ASAP - If HFI due in next week omit HFI or E/P until patch used for 7/7 consecutive days
Contraceptive options for management of HMB
1st line = IUS
2nd = COCP / patch / ring
What is the recommended COCP regimen for women with endometriosis?
continuous
May lead to longer symptom control after conservative surgery
Progestogen only contraception is also 1st line for controlling endometriosis
1st line treatment for menstrual irrgularity for women with PCOS
CHC (COCP / CTP/ CVR) = 1st-line Rx of menstrual irregularity, acne and hirsutism in PCOS.
CHC 1st-line for
adolescent Rx acne, hirsutism or menstrual irregularities
due to anovulation
and pre-menarchal girls with clinical and biochemical evidence of hyperandrogenism in the presence of advanced pubertal development
consider drospirenone containing COCP (yasmin / Yaz)
Non-contraceptive benefits of COCP containing drospirenone
Yasmin / Yaz
Useful for PMDD
May be useful for acne and hirsutism in PCOS
Higher VTE risk
Non-contraceptive benefits of COCP containing cyproterone acetate
= ethinylestradiol and anti-androgen = Co-cyprindol
Higher VTE risk
Not recommended for contraception alone - only prescribed if moderate / severe acne + hirsutism
Evidence re CHC and endometrial cancer risks
CHC use = reduced risk endometrial cancer
correlates with duration of use - persists years after cessation
Evidence re CHC and ovarian cancer risks
reduced ovarian cancer risk in ever-users
Protective effect is duration-dependent
10 years = 50% reduced incidence
Evidence re CHC use and risk of ovarian cancer for women with BRCA 1 or 2 mutations
BRCA gene mutation carriers
use of COCP or POP = reduced risk of ovarian cancer - proportional to duration of use.
evidence stronger for BRCA1
Evidence re CHC use and colorectal cancer risk
Ever users = reduced risk of colorectal cancer
Evidence re CHC use and impact on mortality
No significant association between ever-use of CHC / POP and all-cause mortality
Regardless of duration of use or time since last
use
UK RCGP OC Study = prospective cohort study of 1.3
million woman-years - found ever use of OC = 12%
lower risk of all-cause mortality
Evidence re CHC use and VTE risk
Current COCP use = 3-3.5 -fold increase VTE risk
= Absolute VTE risk during CHC use = 5 - 12 per 10,000 F per yr
compared to 2 per 10 000 non-CHC users
VTE risk lower during CHC use than pregnancy / postpartum
Re COCP use when is VTE risk highest
VTE highest in months immediately after initiation or
restarting after a break of 1 month
risk reduces over 1st year of use + is stable thereafter
Does type of progestogen in CHC impact VTE risk
Yes
Highest risk = CHC containing desogestrel / gestodene / drospirenone or cyproterone acetate = 9–12 per 10,000
Medium risk = CHC containing etonogestrel o / norelgestromin = 6–12 per 10,000
lower risk = CHC containing LNG / Norgestimate / norethisterone = 5–7 per 10,000
Does the dose of ethinyl-estradiol impact VTE risk?
Higher EE dose = greater VTE risk
Limited studies - observational, small numbers of VTE
Does the type of estrogen in CHC impact VTE risk
Most COC = EE.
COC available with estradiol + dienogest or nomegestrol acetate.
Impact on VTE not yet clarified - may have lower VTE risk
Does the route of administration of CHC impact VTE risk?
CTP - conflicting evidence - 1 retrospective cohort + 1 case-control reported sig 2-fold greater VTE risk compared to COC
CVR - Two studies (cohort + case-control) did not find significant difference between CVR and COC
1 cohort study reported increased VTE risk compared to COC users
Evidence re CHC use and MI / stroke / arterial thromboembolism risk
Current use CHC = increased risk ischaemic stroke + MI
Risk related to increasing dose of estrogen
Large Danish cohort = 2.1 thrombotic strokes per 10,000 woman-years
+ 1 MI per 10.000 woman-years
Evidence re current CHC use and breast cancer risk
Danish cohort - relative risk breast ca of 1.2
for current / recent COC users compared to never-users - sported by other studies
Risk may be related to duration of use - conflicting evidence
Evidence re past CHC use and breast cancer risk
Increased breast cancer risk with current COC use declines gradually after cessation of COC
By 10 years cessation = no significant increased risk of breast cancer
Risk may return to baseline by 5 yrs
no significant association between use of COC and mortality from breast cancer
Evidence re COC use and mortality from breast cancer
no significant association between use of COC and mortality from breast cancer
Evidence re use of CHC in women with a family hx breast cancer
Fhx breast cancer = increased background risk
But several studies = F with Fhx + ever used CHC do NOT have higher breast cancer risk
Compared to F with Fhx + never use of CHC
UKMEC does not restrict CHC for F with Fhx
Evidence re breast cancer risk for F with BRCA mutations and CHC use
UKMEC for CHC with BRCA mutations = 3
BRCA = higher background risk breast
cancer - may be further increased by CHC use - conflicting evidence
CHC with BRCA mutations = reduced risk ovarian cancer BUT this advantage needs to be weighed
against potential increased risk breast ca
Evidence re CHC use and cervical cancer risk
Current use of CHC > 5yr = small increased risk cervical cancer
risk reduces over time after stopping CHC
Returns to baseline at ~10yr after stopping
Common Side effects with CHC
And management
headaches,
nausea,
dizziness
breast tenderness.
Can trial different CHC formulation / route - may be more or less tolerable to individuals.
SE may be due to HFI not active pills - Consider shortened HFI or extended/continuous regimens
Or consider non CHC method
Evidence re CHC and headaches
Commonly reported SE
no consistent association between CHC and headache,
Estrogen dose = no impact on headache frequency
Extended /continuous CHC regimens reduce headache frequency associated with HFI
Evidence re unscheduled bleeding with CHC
Common SE - regardless of route
incidence = 10–18% per cycle
Similar to background incidence of IMB
Exclude other causes - missed pills, STI, pregnancy, cervical pathology.
Possibly incidence decreases with time.
Recommend continuing the method for 3 months min
Evidence for differences in bleeding pattern between routes of CHC administration
Bleeding patterns may be better with CVR
No difference between COCP and CTP
Evidence for differences in compliance between routes of CHC administration
Better compliance may be seem with CTP than COCP
Compliance for CVR not studied
Evidence for differences in bleeding pattern related to estrogen doses in CHC
20 μg of EE = higher rates unscheduled bleeding
30μg of EE = lower rates
Evidence for differences in bleeding pattern related to progestogen type in CHC
Less unscheduled bleeding with 3rd gen (desogestrel, gestodene, norgestimate)
compared to 2nd gen (levonorgestrel)
Less unscheduled bleeding with 2nd gen
compared to 1st gen (norethisterone)
Evidence for differences in bleeding pattern related to estrogen type in CHC
COC containing natural estradiol vs EE.
= comparable incidence of unscheduled bleeding
Oestradiol = fewer total bleeding / spotting days
Evidence re CHC impact on mood
Mood change = common complaint - consider different formulation with alt progestogen
But infrequent reason for discontinuation
No clear, consistent evidence CHC causes depression
If negative mood change is premenstrual - try continuous CHC
Data on CVR or CTP are insufficient
Evidence re CHC and weight gain
Limited evidence does not support a causal association between CHC and weight
A systematic review of 9 trials = no evidence association
Evidence re CHC and libido
Evidence mixed and limited
Overall no evidence of association between CHC and libido
Evidence re CHC and return of fertility
No evidence CHC associated with long-term reduction in fertility
Majority F ovulate within 1 month of CHC cessation regardless of regimen used
No evidence increasing duration CHC use is associated with reduced fertility
Which conditions does the FSRH CHC guidelines (2019) state specific attention should be given to enquiring about when considering CHC prescription?
Specific attention should be given to enquiring about: ► Thrombophilia ► Previous VTE ► Ischaemic heart disease ► Stroke or TIA ► Peripheral vascular disease ► Additional risk factors for VTE or ATE (e.g. smoking, obesity, recent childbirth, immobility, HTN, migraine, DM, hyperlipidaemia, antiphospholipid ab, arrhythmia, complicated congenital/valvular heart disease, cardiomyopathy) ► Personal hx breast cancer ► Known breast cancer-related gene mutation ► Hepatobiliary disease ► Recent childbirth ► Current breastfeeding
What measurements or tests should be done before initiating CHC
BP
BMI
Nil else required unless history indicates
What factors may affect absorption of CHC
Effectiveness of COC (not CTP /CVR) could be reduced by malabsorption e.g vomiting severe diarrhoea bariatric surgery small bowel resection inflammatory bowel disease
Why is COC containing ≤30 μg EE with levonorgestrel or norethisterone the suggested first-line choice
To minimise cardiovascular risk.
Key messages for women considering tailored CHC regimens
evidence is that CHC taken in an extended or continuous regimen
► is as safe
► at least as effective for contraception
► Is healthy - women using CHC do not need a monthly withdrawal bleed
► There is no build-up of menstrual blood inside as
extended use keeps the lining thin
► Withdrawal bleeds are not true periods and cannot be relied upon to exclude pregnancy
► Extended or continuous CHC = reduced frequency of withdrawal bleeds and associated symptoms - useful for HMB / dysmenorrhoea
►Ovaries start to become active during traditional 7/7 - Fewer / shorter breaks may mean lower risk of pregnancy
► May have irregular bleeding /spotting for first few months - usually improves with time
► does not affect return of fertility
Indications for urgent medical review when on CHC
Symptoms that should prompt women on CHC to seek urgent medical review
► Calf pain, swelling or redness
► Chest pain / SOB / haemoptysis
► Loss of motor or sensory function
Indications for a non-urgent medical review when on CHC
Key symptoms that should prompt women on CHC to seek medical review
► Breast lump / unilateral nipple discharge / new nipple inversion /change in breast skin
► New onset migraine
► New onset sensory or motor symptoms in the hour preceding onset of migraine
► Persistent unscheduled vaginal bleeding
new diagnoses which should prompt women to discuss contraceptive suitability and review CHC use
New diagnoses of: ► High blood pressure ► High body mass index (>35 kg/m2) ► Migraine or migraine with aura ► DVT / PE ► Blood clotting abnormality ► Antiphospholipid antibodies ► Angina / heart attack ► Stroke ► Peripheral vascular disease ► AF ► Cardiomyopathy ► Breast cancer or breast cancer gene mutation ► Liver tumour ►Symptomatic gallstones
What follow-up is required for women continuing with
CHC?
Routine annual review is recommended annual recording of BP + BM Check medical eligibility and drug history Confirm method adherence Discuss method satisfaction Offer LARC
Travel advice for CHC users re VTE risk
Long duration travel = weak risk factor for VTE.
Risk proportional to duration of travel
Influenced by pre-existing risk factors
CHC could increase risk of travel related VTE
DVT affects 1 : 560 pts flying for 8hr.
PE is extremely rare in flights <8 hours (5:million in >12hr flight)
Indirect evidence re maintaining mobility during travel to reduce risk
Compression stockings / aspirin - not indicated without pre-existing risk factors
Travel advice for CHC users re crossing time zones
Remind women of the importance of taking their
COCP approximately 24 hours after their most recent pill = using the time in the time zone in which the last pill was taken as a reference rather than local time
If this would result in a COCP being due during sleeping hours it is advisable to take one off pill earlier = <24 hrs after last and then continue every 24 hrs in local time
missed COCP = >24 hours since the pill should have been taken
2 pills missed when >72 hours since the last pill was taken - seek advice re EHC + EP 7/7, omit HFI if due
Advice re CHC use at high altitude
Women trekking to high altitudes
(>4500 m / 14,500 feet)
for > 1 week
consider switching to a safer alternative contraception
Why are women trekking to high altitudes for > 1 week
advised to consider switching contraception
high altitude = increased erythropoiesis
And increased thrombosis risk
Advice re CHC use and surgery
Advise stop CHC and to switch to an alternative contraception at least 4 weeks prior to planned major surgery
incl all surgery to the legs or involving prolonged immobilisation of a lower limb
When can CHC be resumed after major surgery
Recommend recommencing at the first menses occurring at least 2 weeks after full mobilisation
If on a progestogen-only method can switch back to CHC once fully mobile
Management of patients on CHC when admitted for emergency surgery / trauma
When discontinuation of CHC is not possible in advance consider thromboprophylaxis (LMWH and compression stockings) is advised
Not required for minor surgery with short anaesthesia
Advice re CHC use aged over 40yrs
Can use CHC until age 50 years
As long as - NO contraindications
After 50yo risks of CHC usually outweigh benefits - advised women to switch to POP, SDI , LNG-IUS or non-hormonal method
Women using CHC for non-contraceptive benefits + wish to continue after 50yo - considered on individual basis
Advice for F >40yo re need for contraception
Use contraception to menopause or age 55
Fertility decreases with age
Chance of pregnancy for 1yr UPSI is 10–20% at age 40–44 and ~12% age 45–49
Advice re pregnancy risks for pregnancy aged 40+
Increased risk of
- maternal mortality
- PPH
- placenta praevia
- gestational diabetes
- pregnancy-induced hypertension
- Caesarean section.
- miscarriage.
- ectopic pregnancy
- stillbirth
- perinatal mortality
- preterm delivery
- congenital anomalies ( non-chromosomal and chromosomal)
Risk of T21 at maternal age 20, 30, 40 and 45
the risk Trisomy 21 for a woman aged 20 = 1 in 1544 aged 30 = 1 in 909 aged 40 = 1 in 146 aged 45 = 1 in 28
Advice re Cu-IUD for F >40yo
Cu-IUD containing ≥300 mm2 copper can be retained until menopause when inserted at age 40+ o = 12m after LMP if LMP occurs age 50+ oe 24m after LMP if LMP occurs before age 50
Advice re LNG-IUS for F age >45yo
Extended use of LNG-IUS for contraception until the age of 55 if inserted at age 45 or over
LNG-IUS for endometrial protection as part of a HRT combination MUST be changed every 5 years
Advice re SDI use for over 40yo
SDI = most effective contraception
0.05% failure rate
No age restriction on its use.
Nexplanon = 68 mg etonogestrel
licensed for 3 years
Extended use not yet supported
What hormone and dose is Nexplanon
Nexplanon® contains 68 mg etonogestrel
Advice re progestogen only injectable contraceptionfor women over 40yo
Women over 40 using DMPA should be reviewed
regularly - Asess benefits + risks
At age 50 advise on alternative methods
DMPA users experience initial loss of BMD due to hypoestrogenic effects - evidence suggests this loss is not repeated or worsened by onset of menopause
% of women who are anovulatory using desogestrel compared to traditional POP
DSG = 97% anovulatory
vs 60% of LNG users
Advice for women considering sterilisation
Advise that some LARC methods are as/more
effective than sterilisation
LARCs may have non-contraceptive benefits
Sterilisation does not alter or eliminate periods
Bleeding patterns may change after sterilisation
because they stop hormonal contraception / have IUS removed.
Vasectomy is safer and quicker and more reliable
Sterilisation is permanent and irreversible on the NHS
Requires laparoscopy with GA
Failure rate 1 in 200
Advice re use of barrier methods for F over 40yo
Use condoms for STI prevention
No age restrictions on barrier methods
Higher effectiveness >40yo due to declining fertility and more consistent use
highly user-dependent
Oil-based lubricants / moisturisers can damage latex condoms
may be an issue if partners experience ED or women have vaginal prolapse or hand dexterity issues
Advice re using natural family planning for women over 40yo
Approaching menopause natural family planning becomes unreliable due to menstrual irregularity increase in anovulatory cycles difficulty interpreting cervical secretions calendar days less reliable
Advice re using the withdrawal method for contraception for F >40yo
Not promoted as a method of contraception - not reliable
Used by 4–6% of women in their 40s
Advice regarding use of EC in women >40yo
No age-related CI for emergency contraception
Offer EC after UPSI to all women >40 if they wish to avoid pregnancy
Perimenopausal women may still ovulate despite
erratic menstrual cyclkes
For a perimenopausal woman estimating earliest day of ovulation may be difficult - but ALWAYS offer a Cu-IUD when safe
At what age can all contraception be stopped?
All women can cease contraception at age 55 - spontaneous conception after this is exceptionally rare
If age 40–50 years - stop contraception once 2 years after LMP
If age 50+ stop contraception 1yr after LMP
If required - can measure hormone levels whilst on POC but not CHC methods
TIming for fitting of IUC after childbirth
IUC can be safely inserted after delivery of the placenta
or within the first 48 hours after uncomplicated caesarean section or vaginal birth.
Avoid insertion between 48 hours until 28 days after childbirth.
TIming for fitting of SDI after childbirth
SCI can be safely fitted at any time after childbirth including immediately after delivery.
TIming for starting of POIC after childbirth
Progestogen-only injectable contraception can be started at any time after childbirth
including immediately after delivery.
TIming for starting of POP after childbirth
POP can be started at any time after childbirth
including immediately after delivery.
TIming for starting of CHC after childbirth
If VTE risk factors - delay CHC use until 6weeks PN
If breastfeeding - delay CHC use until 6weeks PN
If not breastfeeding and no additional VTE risk factors - wait until 21 days after childbirth before initiating CHC
Recommended minimum timefreame for obtaining written consent for F sterilisation at the time of elective CS
written consent for sterilised at caesarean section is advised to be obtained and documented
at least 2 weeks in advance
of a planned elective caesarean section.
Advice re use of diaphragm after childbirth
Women choosing to use a diaphragm after childbirth should be advised to wait at least 6 weeks
When is EC indicated after an abortion
EC is indicated if UPSI occurs from 5 days after abortion

Advice re managing a patient with an IUC in situ who has asymptomatic women with actinomyces-like organisms.
There is no need to remove IUC in asymptomatic women with ALOs.
Advice re use of Mooncups or tampons after IUC fitting
Mooncups and tampons do not appear to be associated with an increased risk of IUC expulsion
Advice re quick starting contraception if pregnancy cannot be excluded
A negative high-sensitivity UPT cannot reliably exclude pregnancy until ≥21 days after the last UPSI
If -ve HSUPT but at risk from recent UPSI advise
- EC may be indicated
- CHC / POP / implant can be quick started
- DMPA may be QS if other methods not suitable /acceptable
- IUS cannot be QS
- Cu-IUD can be QS if conditions for EC use are met
- After LNG-EC can QS CHC, POP, IMP (and DMPA) immediately
- After UPA-EC - wait 5/7 before QS hormonal contraception
- EP required until QS method is effective
