Q

How are the gonadotrophins LH and FSH involved in fertility?

A

LH - stimulates Leydig cells to increase intratesticular testosterone levels (much higher than in circulation)
FSH - stimulates seminiferous tubule development and spermatogenesis

Q

What are the effects of the combined OCP on the HPG axis?

A

Oestrogen and prog - negative feedback - decrease GnRH, LH and FSH

Ovaries:

Q

What are the negatives of OCP use?

A

It can be difficult to remember
No protection against STIs
P450 Enzyme Inducers may reduce efficacy
Not the best choice during breast feeding

22
Q

What are the possible side effects of the OCP?

A

Spotting (bleeding in between periods)
Nausea
Sore breasts
Changes in mood or libido
Feeling more hungry (can try different OCPs to see which suits best)
Blood clots in legs or lungs (extremely rare)

23
Q

What are the non-contraceptive uses of the OCP?

A
  1. Helps make periods lighter and less painful
    - Endometriosis / Fibroids
    - Dysmenorrhoea (painful periods)
    - Menorrhagia (heavy periods)
  2. Regular Withdrawal Bleeds / or no Bleeds
  3. PCOS: OCP can help reduce LH and hyperandrogenism (acne / hirsutism)
24
Q

What are the positives of taking the Progesterone Only Pill?

A

Works as OCP but less reliably inhibits ovulation
Often suitable if can’ttake oestrogen
Easy to take – one pill per day with no break
It doesn’t interrupt sex
Can help heavy or painful periods
Periods may stop (temporarily)
Can be usedwhen breastfeeding

25
What are the negative of taking the POP?
Can be difficult to remember No protection against STIs Shorter acting – needs to be taken at the same time each day
26
What are the possible side effects of the POP?
Irregular bleeding Headaches Sore breasts Changes in mood Changes in sex drive
27
What are the different types of Long-Acting Reversible Contraceptives (LARC)?
Coils - Intra-uterine Device (IUD i.e. copper coil - Intra-uterine systems (IUS) which secretes progesterone (e.g. Mirena Coil) Progesterone-only injectable contraceptives or subdermal implants
28
What must be considered before using a coil?
Suitable for most women Prevent implantation of conceptus – important for some religions Rarely can cause Ectopic Pregnancy Can be used as emergency contraception
29
What are the differences between an IUD and IUS?
IUD: - Mechanically prevent implantation, decrease sperm / egg survival - Lasts 5-10yrs - Can cause heavy periods, and 5% can come out especially during first 3months with periods IUS: - Secretes progesterone (eg Mirena Coil) to thin lining of the womb and thicken cervical mucus - Can be used to help with heavy bleeding - Lasts 5yrs
30
What must be considered before using Progesterone-only injectable contraceptives?
Long lasting - not the best option if desiring fertility soon
31
What is the most effect emergency contraception?
Copper IUD - can be fitted up to 5 days after unprotected sex (<1% chance of pregnancy)
32
What are the two main emergency contraceptive pills?
Ulipristal acetate 30 mg (ellaOne) - Stops progesterone working normally and prevents ovulation - Must be taken within 5 days of unprotected intercourse (earlier has better efficacy) - 1-2% can get pregnant if ovulation has already occurred Levonorgestrel 1.5 mg (Levonelle) - Less effective (esp if incr BMI >27 kg/m2) - Synthetic Progesterone prevents ovulation (don’t cause abortion) - Must be taken within 3 days of unprotected intercourse - 1-3% failure rate
33
What are the side effects and consideration for emergency contraceptive pills?
Side effects: Headache, abdominal pain, nausea Considerations: - Liver P450 Enzyme inducer medications make it less effective - If vomit within 2-3hrs of taking it, need to take another
34
Compare the efficacy of different types of contraception
35
What are some contraindications for OCP use and when should they be avoided?
Contraindication for OCP: Risk of Venous Thromboembolism (VTE) / CVD / Stroke Avoid OCP if: - Migraine with aura (risk of stroke) - Smoking (>15/day) at age >35yrs - Stroke or CVD history - Current breast cancer
36
What are some other considerations for OCP use?
- Other conditions may benefit from OCP eg Menorrhagia / Endometriosis / Fibroids / PMS (Pre-Menstrual Syndrome) / acne or hirsutism - Need for prevention of STIs - barrier methods better than hormonal - Concurrent medication — P450 liver enzyme-inducing drugs (eg anti-epileptics, antibiotics) effect efficacy of OCP Teratogenic drugs (eg lithium or warfarin) - more effective methods of contraception needed (eg progestogen-only implant, or intrauterine contraception) - Ease of use
37
Distinguish between peri-menopause, menopause and post-menopause
Peri-menopausal- Within the years leading up to menopause Menopause- Time at 12 months since last menstrual period LMP Post-menopausal- After menopause
38
What are the benefits of HRT?
Symptom relief due to low oestrogen eg flushing, sweats, disturbed sleep, decreased libido, low mood Reduction in osteoporosis related fractures
39
What are some risks of HRT?
- Venous Thrombo-embolism: Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE) - Hormone Sensitive Cancers, e.g. breast, ovarian and endometrial - Cardiovascular disease - Risk of stroke
40
How does HRT increase the risk of VTE and what can be done to reduce this?
Oral oestrogens undergo first pass metabolism in liver Oral -> Increase clotting factors Transdermal estrogens are safer for VTE risk than oral Avoid oral oestrogens in BMI > 30 kg/m2
41
Describe the implications of HRT on breast cancer risk
Slight increase in women on Combined HRT Risk related to duration of treatment and reduces after stopping Continuous worse than sequential Assess risk in each individual before prescribing
42
Describe the implications of HRT on ovarian cancer risk
Small increase in risk after long-term use
43
Describe the implications of HRT on endometrial cancer risk
Must prescribe Progestogens in all women with an endometrium Progestogens: synthetic progestins and the natural hormone progesterone Post-menopausal bleeding could indicate endometrial cancer
44
Outline the factors affecting risk of CVD due to HRT
Improved risk in younger women and recently post-menopausal Increased risk if started later i.e. 10 years after menopause Likely benefit in younger women e.g. Premature Ovarian Insufficiency (POI)
45
Outline the factors affecting risk of stroke due to HRT
Small increased risk Oral have more risk than transdermal oestrogens Combined (E2+P) more risk than oestrogen only
46
Summarise the risks of HRT
47
Weight the benefits and risks of HRT
48
How do you treat transgender men?
Testosterone (injections, gels) Progesterone to suppress menstrual bleeding if needed (endometrial hyperplasia 15%)
49
How do you treat transgender women?
1. Reduce Testosterone - GnRH agonists (induce desensitisation of HPG axis) - Anti-Androgen medications 2. Estrogen (transdermal, oral, intramuscular) High dose oestrogen eg 4-5mg per day (side-effects: higher risk of VTE 2.6%)
50
How are prepubertal young people who would like to change gender supported?
Prepubertal Young people – GnRH agonist to delay puberty Waiting list for specialist clinic ~4yrs Post-treatment regret - 1-2% Gender Reassignment surgery after ~1-2 yrs of hormonal treatment
