PCOS is one of the most common, but treatable, causes of infertility in women. In women with PCOS, the hormonal imbalance interferes with the growth and release of eggs from the ovaries (ovulation). Without ovulation, pregnancy is unattainable. The ovaries also tend to be larger than normal and can have many tiny cysts that contain immature eggs. Having said that, please note that if you have PCOS, it does NOT mean that you cannot get pregnant!
PCOS causes a woman’s body to produce higher-than-normal levels of androgens. These are hormones that are usually thought of as male hormones, because men have much higher levels of androgens than women. Androgens are important in the development of male sex organs and other male traits. In women, androgens are usually converted into the hormone estrogen.
