What is PCOS? Increased androgen production from

ovaries and adrenal glands

What does it mean to have PCOS? Well, unfortunately, it means a lot of difficult things for many women. I started to have facial hair growth in early highschool -- this was pretty embarassing, especially when I realized that it wasn't "normal" compared to my other friends. Of course, I had lots of hair on my legs and arms too, at an even younger age -- growing up in Southern California meant that I was doing a lot of hair removal all the time so as to not look like a freak in shorts or a bathing suit. My skin just didn't ever seem to clear up -- I spent many hours at the dermatologist. I also "learned" early on that I couldn't eat very much at all -- if I did, I immediately gained a lot of weight and it didn't want to come off. My cycles were horrible, when I had them, I understood why some women called it "the curse".

I was diagnosed when I was 17 and immediately went on birth control pills to control my symptoms. This was the only practical "treatment" known at that time. Later on, PCOS was the reason I couldn't easily conceive and then miscarried the 2 times I did conceive naturally. I think this is the most acutely painful aspect of this syndrome, and it is certainly the focus of many women's pain. Wanting a child and being unable to have one was one of the most difficult times of my life. Needing to take in order to conceive and carry a pregnancy can have some very subtle effects on how a woman thinks about herself, and when she has a condition that already makes her feel less attractive, less desirable and less feminine (at least by our culture's standards), she can end up seeing herself as pretty defective. Later in life, PCOS presents some serious health problems. Women with PCOS are significantly more likely to have type II diabetes and heart disease and there appears to be a link to breast and colon cancer, so it isn't just a "cosmetic" or "infertility" condition -- it can be ugly.

PCOS Spectrum of clinical d/o’s not

diagnosed by lab Clinical presentation includes:

Hirsuitism & acne Obesity Oligomenorrhea Anovulation Infertility

PCOSPituitary gland is heightened to GnRH ↓Exaggerated pulsatile LH release ↓LH/FSH ratio may be elevated ↓↑ LH stimulate ovary to secrete ↑ androgen ↓

Androgens are converted to estrone and estradiol ↓

Estrogens secreted tonically ↓

Augment pituitary sensitivity to GnRH ↓

And vicious cycle continues to ↑ LH ↓

ovaries overproduce androstenedione and testosterone

Other interesting findings Androgens ↓ SHBG; ↑ free testosterone Anovulation and insulin resistance- exact

pathogenesis unclear ↑in basal insulin secretion ↓in hepatic uptake B-cell dysfunction ↑insulin has direct effect on pituitary in ↑LH

secretion and the ovary for androgen production

Problems associated with high levels of sex hormones:

Anovulation results in amenorrhea & infertility

Hirsuitism, acne Male pattern

baldness/thinning Obesity- android-type

with ↑waist-hip ratios Cancer- endometrial

Problems associated with high levels of sex hormones:

Insulin resistance

Hyperinsulinemia

Diabetes

Cardiovascular disease

Theories to etiology of PCOS

Genetic predisposition is most likely although no gene isolated; believe in 2-hit hypothesis

Premature adrenarche (<8 y/o) Heterozygosity for CAH IUGR

Treatment Cosmetic interventions

OCP’s: suppress LH → ↓androgens ↑SHBG → ↓free testosterone ↓adrenal production of androgen ↓ 5alpha-reductase

Spironolactone

Treatment Cyclic progestins

GnRH agonists

Weight control Low carb diets

Exercise to reduce weight and CV risk factors

Treatment- controversial

Insulin sensitizing drugs: biguanides & thiazolidinediones ↓ insulin R ↓ hirsuitism restore nl ovulatory patterns

Metformin Reduces hyperinsulinemia Decreases risk factors for CHD Improved weight-loss Normalization of circulating

androgens Resumption of normal ovulatory

menses and therefore reversal of infertility
