Q

How do gonadotrophins stimulate spermatogenesis?

A

LH stimulates Leydig cells to increases intratesticular testosterone levels much higher than in circulation (x100).

FSH stimulates seminiferous tubule development and spermatogenesis.

Q

How many ovarian follicles are we aiming to develop through ovulation induction and why?
How is this acheived?

A

Aim to develop one ovarian follicle

22
Q

what are the permanent methods for contraception?

A

vasectomy
female sterilisation

23

can interrupt sex
can reduce sensation
can interfere with erections
some skill needed to use e.g. correct fit

Q

how does the combined oral contraceptive pill act for contraception?

A

high oest and prog negative feedback on LH/FSH
low LH/FSH cause anovulation
prog thickens cervical mucus
thinning of endometrial lining to reduce implantation

Q

what are the positives for the combined OCP?

A

Easy to take – one pill a day (any time of day)
Effective
Doesn’t interrupt sex
Can take several packets back to back and avoid withdrawal bleeds
Reduce Endometrial and Ovarian Ca
Weight Neutral in 80% (10% gain, 10% lose)

27
Q

what are the negatives for the combined OCP?

A

may not remember to take it
no protection against STIs
P450 enzyme inducers may reduce efficacy
not best choice during breastfeeding
Possible side effects:
Spotting (bleeding in between periods)
Nausea
Sore breasts
Changes in mood or libido
Feeling more hungry
(try different OCPs to see which suits best)
Extremely rare side effects:
Blood clots in the legs or lungs

28
Q

what are the non-contraceptive uses of the combined 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 helps reduce LH and hyperandrogenism (acne / hirsutism)
29
Q

what are the positives of the mini 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

30
Q

what are the negatives of the mini pill?

A

Can be difficult to remember
No protection against STIs
Shorter acting – needs to be taken at the same time each day

Possible side effects
Irregular bleeding
Headaches
Sore breasts
Changes in mood
Changes in sex drive

31
Q

what are long acting reversible contraceptives? (LARC)

A

intra-uterine devices, intrauterine systems, subdermal implants, progesterone only injections

32
Q

Advantages and disadvantage of using coil ascontraception

A

Suitable for most women
Prevent implantation of conceptus – important for some religions
Can be used as emergency contraception

Rarely can cause Ectopic Pregnancy

33
Q

what is an IUD?
Disadvantages
Example

A

a LARC mechanically preventing implantation, decreasing
sperm / egg survival. Lasts 5-10yrs.
Can cause heavy periods, and 5% can come out especially during first 3months with periods.

e.g copper coil

34
Q

what is an IUS?
Example

A

Used to thin lining of the womb and thicken cervical mucus (can be used to help with heavy bleeding). Lasts 5yrs.
e.g mirena coil

35
Q

what are the choices for emergency contraception?
How longafter unprotected sex can these be fitted?
How effective are they?

A

copper coil (most effective) can be fitted up to 5 days after unprotected sex (<1% chance of pregnancy)

contraceptive pill - ulipristal acetate 30mg- Must be taken within 5 days of unprotected intercourse (earlier has better efficacy).
1-2% can get pregnant if ovulation has already occurred.

levonorgestrel 1.5mg- Must be taken within 3 days of unprotected intercourse. 1-3% failure rate.

36
Q

what is the ulipristal acetate emergency contraceptive? (ellaOne)

A

stops progesterone working normally
prevents ovulation

37
Q

what is the levonorgestrel emergency contraceptive pill? (levonelle)

A

synthetic progesterone prevents ovulation
doesnt cause abortion

38
Q

what are the side effects of emergency contraceptive pills?

What drug class interferes with emergency contraceptive pills action?

A

headache, abdo pain, nausea- If vomit within 2-3hrs of taking it, need to take another.
Liver P450 Enzyme inducer medications make it less effective.

39
Q

what are the contraindications for combined OCP?

A

Migraine with aura (risk of stroke)
Smoking (>15/day) at age >35yrs
Stroke or CVD history
Current Breast cancer

40
Q

what medications may interact with the combined OCP?

A

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).

41
Q

Symptoms of menopause

A

Hot flushes, sweating, disturbed sleep,
Low libido, vaginal dryness, low mood.
Joint and muscle aches

42
Q

Benefits of HRT

A

Symptomatic relief
Reduction in Osteoporosis related fractures

43
Q

what are the risks for hormone replacement therapy in menopause?

A

venous thrombo-embolism
hormone senstive cancers
increased risk of CV disease
risk of stroke

44
Q

why is venous thrombo-embolism a risk for oral oestrogen HRT?
How can wereduced this risk?

A

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

45
Q

why are hormone sensitive cancers a risk in oestrogen HRT?

A

Slight increase in women on Combined HRT
(ie oestrogen AND progesterone)
Risk related to duration of treatment and reduces after stopping
Continuous worse than Sequential
Assess risk in each individual before prescribing

Ovarian cancer- Small Increase in risk after long-term use.

Endometrial Cancer-
Must prescribe Progestogens in all women with an endometrium !
Progestogens: synthetic progestins
and the natural hormone progesterone.
Post-menopausal bleeding could indicate endometrial cancer

46
Q

what is the cardiovascular disease risk of oestrogen HRT?

A

Improved risk in Younger Women & Sooner after Menopause
Increased risk if started later i.e. 10 years after menopause
Likely benefit in younger women e.g. Premature Ovarian Insufficiency (POI)

47
Q

what is the risk of stroke with oestrogen HRT?

A

Small increased risk
Oral have more risk than transdermal oestrogens
Combined (E2+P) more risk than oestrogen only

48
Q

which transgender gender is more common?

A

transgender women 3x more common than transgender men

49
Q

what is the process for transgender treatment?

A

in prepubertal young people - GnRH agonist for pubertal suppression and then sex steroids
gender reassignment surgery after 1-2 years of hormonal treatment

50
Q

what are the masculising hormones for transgender men?

A

testosterone (injections, gels)
progesterone given to suppress menstrual bleeding if needed

51
Q

what are the feminising hormones for transgender women?

A
  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
52
Q

what should be monitored when giving testosterone ton males not desiring fertility?

A

haematocrit - risk of stroke/hyperviscosity

prostate specific antigen - risk of prostate cancer

53
Q

first line treatment for PCOS?

A

metformin for weight loss
letrozole - aromatase inhibitor
inhibits test-oestr

54
Q

Symptoms of low testosterone?

A

loss of early morning erections, libido, decreased energy,decreased shaving frequency
