PCOS 2 av 3 kriterier 1. Oligomenorre (glesa menstruationer) eller amenorre (ingen mens) 2. Klinisk eller biokemisk hyperandrogenism Hirsutism Förhöjt fritt androgenindex Testosteron/SHBG >0.05 3. Typisk ultraljudsbild Många antralfolliklar i äggstocken
Klinisk bild varierande Prevalenssiffror mycket varierande 1,5 % i Svenska register 6,5% i Svensk prevalensstudie Omkring hälften av kvinnorna är överviktiga i Sverige Skandinaviska kvinnor har mindre besvär med hirsutism än andra nationaliteter Stark heritabilitet men den manliga fenotypen kan ej urskiljas

Gynekologens fundering.. Är detta ett orsakssamband? Testosteronexponering i fosterlivet? Eller beror det på att dessa kvinnor i högre grad remitteras till gyn? Eller beror det på att de läkemedel ni använder leder till obesitas och metabola förändringar?

Hur blir hjärnan manlig eller kvinnlig? Hjärnan har full potential att utvecklas till både manlig och kvinnlig fenotyp. Default mode är en kvinnlig hjärna Maskulinisering av hjärnan sker under kritisk period i fosterlivet Testosteron hos människa Östrogen hos gnagare
Maskulinisering Det manliga fostret producerar lika mycket testosteron som en 25 årig man
Testosteronsyntes Flickfostrets ovarier tysta Hormonproduktion från binjurar Kortisol och testosteron närliggande DHT utveckling av manliga genitalier, finns i princip inte hos kvinnor Aromatas omvandlar testosteron till östrogen

The menstrual cycle
The ovary Oogenesis Primordial and primary follicles 7 millon in the female fetus 2 million at birth 400 000 at puberty Antral follicles mature at puberty 400 ovulations
No ovarian stem cells (so far) Nature 2012 Nature Medicine 2015
Hypothalamus pituitary gonadal axis +
GnRH neurons Surprisingly few Longest migration of all neurons during neurodevelopment Odd morphology with synapses all along the dendrite (dendrone) No estrogen or progesterone receptors
GnRH pulsatility Slow pulsatility favors FSH relase Fast pulsatility favors LH release The mechanism behind the GnRH pulsatility is virtually unknown Except the LH surge
Positive feedback mediated by kisspeptin
The menstrual cycle is controlled by the ovary FSH stimulation Follicular recruitment Estradiol production and expression of FSH receptors Increased estradiol levels turns off the FSH stimulation
Selection of the leading follicle Estradiol levels > 730 pmol/l for more than 50 hours triggers the positive feedback mechanism on LH release.
The corpus luteum The leading follicle matures into a corpus luteum after ovulation Capable of estradiol and progesterone synthesis Preparations for implantation and pregnancy
The endometrium Follicular phase; proliferation Luteal phase: maturation, spiral arteries and glands
The implantation window
Implantation Glucose, lactate and pyruvate are required for human blastocyst development Blastocysts communicate with the endometrium Human chorionic gonadotropin (hcg) is secreted by hatched human blastocysts in close apposition to the endometrium The endometrium produces leukaemia inhibitory factor (LIF), VEGF, IL 11 and other chemokines and cytokines mirnas in uterine fluid are taken up by pre implantation mouse embryos and alter embryonic mrna expression in vitro
A few words on puberty
Pubertal development
Kisspeptin central for puberty
Puberty
Early puberty More frequently in girls but appear to occur also in boys impact somatic and psychological maturation adult height psychosocial problems Earlier puberty is associated with an increased risk of cardio metabolic disease, including hypertension and Type 2 diabetes, in both men and women Causation? Kisspeptin not acting on its own; leptin, NPY and many more SNPs at or around genes known to influence body weight (e.g. FTO) or energy homeostasis (e.g. the receptor of the orexigenic factor MCH, or the transcription factors BSX and CRTC1) have been shown to associate with modest variations in the age of puberty
Reproductive research, why?
The pill
In vitro fertilization
IVF success rates IVF success rates have remained static at around 25 30% Elevated oxygen concentrations may have a negative impact through oxidative stress Oxygen levels that are too low may impair embryogenesis po 2 within the female reproductive tract shows cyclical variation and minute tominute oscillations, influenced by uterine contractility, hormones, the autonomic system, cardiac pulsatility, and myometrial and smooth muscle integrity. ph is important for sperm binding and motility, oocyte maturation and embryo development The ph in the female reproductive tract is graduated, with lowest ph in the vagina (ph 4.42) increasing toward the Fallopian tubes (FTs) (ph 7.94). In humans, temperature is biphasic, increasing in the luteal phase; with the caudal region of the oviduct 1 2 degrees cooler than the cranial portion.
Obesity a new challenge in research BMI has been associated with delayed conception in women in a dose dependent fashion Obesity lead to anovulation and menstrual irregularity impairment of oocyte development and quality has direct effects on the endometrium With ovulation induction (OI) treatment, higher doses of medications longer period of stimulation With IVF the chances of achieving a pregnancy decrease with each unit increase in BMI implantation rates are lower in obese increased risk of miscarriage following IVF.
Sperms Decline in sperm counts between 1973 and 2011, driven by a 50 60% decline among men unselected by fertility from Western countries
Obesity and fertility in men Increased testicular temperature Increased oestrogen production in fat with disruption of the hypothalamo pituitary gonadal axis Reduced sperm concentration and motility Lower clinical pregnancy rates with IVF
Delayed childbearing At least, social freezing works Vitrification was associated with increased ongoing CPR per cycle in comparison with slow freezing embryos (RR = 2.81, 95% CI: 1.05 7.51; P = 0.039) In vitrification and fresh cycles, respectively, no evidence for a difference in clinical pregnancy rate per randomized woman (RR = 1.03, 95% CI: 0.87 1.21; P = 0.744)
