reproductive treatment Flashcards
restore ovulation for PCOS
1) Lifestyle
2)metformin
3)letrozole (aromatase inhibitor)
4)clomiphene (oestradiol receptor modulator)
5) FSH stimulation
restore ovulation for hypothalamic amenorrhoea
1.Lifestyle / Weight gain / reduce exercise
2.Pulsatile GnRH pump
3.FSH stimulation
4.Letrozole (Aromatase inhibitor)
5.Clomiphene (Oestradiol receptor modulator)
IVF treatment
- oocyte retrieval
- fertilisation in vitro
- embryo incubation
- embryo transfer
how does Oral contraceptive pill work
- anovulation
- thickening of cervical mucus
- thinning of endometrial lining to reduce implant
has oestrogen/progesterone which negatively feedback and decreases LH/FSH
non contraceptive use of OCP
- help make periods lighter and less painful
-PCOS- reduce LH and hyperandrogenism (acne/hirsutism)
difference between POP(mini pill) and OCP
POP
suitable if pt cannot take oestrogen
shorter acting- take same time everyday.
can be used while breastfeeding
OCP
cannot be used while breastfeeding
can take anytime everyday
examples of LARC(long acting reversible contraceptives)
coils (IUD) (5-10 years)
Mirena coil (IUS) (5 years)
progestogen-only injectable contraceptives/
subdermal implants
emergency contraception
1) IUD- up to 5 days after unprotected sex
2) ulipristal acetate - stops progesterone working normally and prevent ovulation. Taken within 5 days of unprotected sex
3) levonorgestrel - synthetic progesterone prevent ovulation- taken within 3 days
nausea, abdominal pain
if vomited within 2-3 hr: take another
consideration for contraception choice
- contraindication OCP
- other condition that may benefit
3.Check STI - concurrent med
- ease of use
when to avoid OCP
Migraine with aura (risk of stroke)
Smoking (>15/day) at age >35yrs
Stroke or CVD history
Current Breast cancer
(risk VTE/CVD/Stroke)
pros of HRT
Pros
-symptom relief from low oestrogen
-reduce osteoporosis related fractures
what is progestogens
synthetic progestins and natural progesterone
cons of HRT
cons
1. VTE (DVT/PE) risk- as drug increases clotting factors
-transdermal oestrogen safer for VTE than oral
2.breast cancer-combined HRT.
ovarian cancer- LT use
-assess risk in individual before prescribing
endometrial cancer- prescribe progestogen. post-menopausal bleeding- indicate endometrial cancer
- CVD
decrease-younger women (POI)
increase- started later after menopause
4.stroke risk
oral higher risk than transdermal
Transgender Men: Treat with Masculinising Hormones :
- Testosterone (injections, gels)
- Progesterone- suppress menstrual bleeding if needed (endometrial hyperplasia 15%).
Transgender Women: Treat with Feminising Hormones :
- Reduce Testosterone
GnRH agonist-desensitisation HPG axis.
Anti-Androgen medications. - Estrogen (transdermal, oral, intramuscular)
High dose oestrogen
SE: risk VTE 2.6%
