transvaginal uss - gold standard.
follicles around periphery of ovary (STRING OF PEARLES)

FSH,LH,PROLACTIN,TSH,TESTOSTEONE,SEX HORMONE BINDING GLOBULIN(SHBG)

raised lh:fsh ratio
prolactin: normal/mildly elvated
testosterone: poss normal/mildly elevated
SHBH - normal to low

Q

what is the diagnostic criteria for pcos?

A

Rotterdam criteria: 2 of following 3

  1. infrequent or no ovulation
  2. clinical/biochemical signs of hyperandrogenism (hirsutism, acne, elevated levels of total/free testosterone)
  3. polycystic ovaries on uss scan - 12 or more follicles (2-9mm in diameter) in 1 or both ovaries and/or increased ovarian vol over 10cm^3

Q

Management of pcos

A

weight reduction if poss. - orlistat : lipase inhibitor
combined oral contraceptive if need contraception - regulate her cycle and induce monthly bleed.

hirsutism and acne:
- COC pill. 3rd gen.- fewer androgenic effects or co-cyprindiol (has anti-androgen action) - both have VTE risk.
- if doesnt respond to COC : topical eflornithine
-spironolactone, flutamide, finasteride - specialist supervision

infertilityL
- weight reduction
- poss metformin,clomifene or combo to stimulate ovulation.
- use metformin either with clomifene or alone - esp in obese
-gonadotrophins

Q

how might a oral ccp help regulate cycle and induce monthly bleed?

A
  1. occupy hypothalamic oestrogen receptor without activating them.
  2. interferes with binding of oestradiol
  3. prevents negative feedback inhibition of FSH secretion.

Q

how does insulin resistance play in pcos?

A

insulin resist pt, pancreas produces more insulin.
promotes release of androgens from ovaries and adrenal glands

insulin also suppresses SHBH production by liver. it would normally bind to androgens and suppress the function.

high insulin halt development of follicles in overaies = anovulation. and multiple partially developed follicles - Polycstic ovaries.

features of ovarian torsion

On examination

A

vomiting and distress

fever in minority - poss secondary to adnexal necrosis.

occasionally : can be not that severe and ovary can twist and untwist intermittently, causing pain that comes and goes.

on exam: localised tenderness. poss palpable mass in pelvis. - absense of mass doesnt exclude the diagnosis.

simple ovarian cyst in premenopause:
- less than 5cm: will resolve within 3 cycles.
- 5-7cm : refer to gynae and annual uss.
- 7+cm - MRI or surgery.

postmenopause :
- correlate with ca125 and refer to gynae.
-if raised - 2 week wait.
- simple cyst under 5cm with normal ca125 - uss every 4-6 months.

persistent or enlarging cysts : SURGERY WITH LAPAROSCOPY. could be:
- ovarian cystectomy

Q

how does prolactin affect testes and ovaries?

A

prolactin inhibits gonadotropin-releasing hormone by hypothalamus.

inhibits HPA axis.
low GnRH = anterior pituitary produces less LH and FSH resulting in:

  • reduced stimulation of testes in men = low testosterone production
  • reduced stimulation of ovaries in women = absent ovulation, absent periods

aetiology of endometriosis

A

-genetic?

  • during menstruation, endometrial lining flow back through fallopian tubes and out into pelvis and peritoneum - RETROGRADE MENSTRUATION. - tissue then seeds itself around pelvis and peritoneal cavity.
  • cells outside uterus undergo metaplasia - from typical cells into endometrial cells
  • spread of endometrial cells through lymphatic system
  • embryonic cells remain in areas outside uterus during fetus development and later develop into ectopic endometrial tissue

in infancy

inguinal hernias containing testes.
or
puberty with primary amenorrhoea.

have testes - in abdo or inguinal cancal

no uterus upper vagina cervix fallopian tube and ovaries.

196

testes produce anti-mullerian hormone.

prevents males from getting upper vagina uterus cervix fallopian tubes.

197
Q

Physiology of menopause

decline in development of ovarian follicles.

reduced oestrogen production.

negative feedback on pituitary gland not happening, so increased levels of LH and FSH.

anovulation

irregular menstrual cycles.

endometrium doesnt develop - amenorrhoea

bilateral oophorectomy - having hysterectomy with preservation of ovarian has also been shown to advance age of menopause

radio
chemo
infection: mumps

resistant ovary syndrome: due to fsh receptor abnormalities

200
Q

climactreric sx: hot flushes , night sweats
infertility
secondary amenorrhoea

raised fsh,lh levels
fsh over 30
elevatred fsh on 2 blood samples 4-6 weeks apart.

low oestradiol : under 100 pmol/L

201
Q

how would you manage premature ovarian syndrome?

A

hrt or combined oral contraceptive - until 51 (menopase)

hrt doesnt give contraception in case sponaneous ovarian activity resumes.

202
Q

Explain the hypothalamic-pituitary gonadal axis in women

A

hypothalamus releases GnRH

that stimulates anterior pituitary to release lh and fsh

lh and fsh stimulate follicle development in ovaries.

cause theca granulosa cells to secrete oestrogen, which negatively feed back to hypothalamus and AP, reducing LH and FSH levels.

203
Q

What is oestrogen and what does it stimulate?

A

steroid sex hormone (17-beta oestradiol is main active version)

  • breast tissue development
  • growth and development of female sex organs (vulva,vagina,uterus) at puberty
  • blood vessel development in uterus
  • development of endometrium
204
Q

What is progesterone and what does it stimulate?

A

steroid sex hormone produced by corpus luteum after ovulation.

in pregnancy produced by placenta from 10 weeks gestation onwards.

acts on tissues previous stimulated by oestrogen?

  • thickens and maintains endometrium
    -thickens cervical mucus
    -increases body temp
205
Q

what age does puberty occur in girls, how long does it last and in what sequence do changes occur?also why does low weight delay puberty.

what staging is used

A

8-14 yrs
4yrs

growth spurt/breast buds, pubic hear, menarche

aromatase found in adipose tissue helps create oestrogen.

more aromatase (Fat) = earlier puberty. low birth weight, chronic disease/ED, athletic hence cause cause delays.

Tanner staging (under 10, no pubic hear or breasts =1 )

206
Q

2 phases of menstrual cycle

A

follicular phase - start of menstruation to ovulation - 1st 14 days

luteal phase - ovulation to start of menstruation - final 14 days

207
Q

what are ovarian follicles?

A

oocytes are cells that have potential to develop into eggs. surrounded by granulosa cells , forming follicles.

primary follicles are always maturing into primary and secondary follicles.

when they reach secondary, they grow FSH receptors, which when stimulated, cause granulosa cells to secrete oestradiol. (oestrogen)

208
Q

Describe the follicular phase

A

Low oestrogen and progesterone causes endometrium shedding and bleeding.

FSH stimulates secondary follicles, causing them to grow, and for surrounding granulosa cells to secrete oestrogen. This reduces LH and FSH production (negative feedback). Rising oestrogen also causes cervical mucus to become more permeable, allowing sperm to penetrate cervix around ovulation.

One follicle will develop more than the rest (dominant follicle) LH spike causes dominant follicle to release an ovum. Ovulation occurs 14 days before end of cycle.

Overall: FSH stimulates oestrogen, which spikes ~day 12. There is an LH spike right before ovulation causing an ovum to release.

209
Q

Describe luteal phase

A

The follicle that released the ovum collapses, becoming the corpus luteum. This secretes progesterone, maintaining the endometrial lining. It also causes the cervical mucus to become thick.

If pregnancy: the syncytiotrophoblast of the embryo secretes Human Chorionic Gonadotrophin (HCG), maintaining the corpus luteum.

Without fertilisation the corpus luteum degenerates and stops producing oestrogen and progesterone. This fall causes breakdown of the endometrium and menstruation. The stromal cells in the endometrium release prostaglandins, causing uterus contractions. The fall in Oestrogen and Progesterone causes an increase in LH and FSH, restarting the cycle.

Menstruation marks day 1 of the menstrual cycle.

210
Q

What is amenorrhoea? Give primary and secondary causes?

A

failure to establish menstruation at 15 with normal sexual development and 13 without.

Primary
- Gonadal dysgenesis (e.g. Turners)
- Hypogonadotrophic hypogonadism (deficiency of LH and FSH), Hypergonadotrophic hypogonadism (lack of response to LH and FSH by gonads)
- Pregnancy

Secondary - 3-6 months amenorrhoea when previously normal
- Hypothalamic (secondary stress, excessive exercise)
- PCOS
- Thyroid disease
- Hyperprolactinaemia
