In PCOS, the ovaries produce more male hormone ie androgen (like testosterone). Testosterone is called a “male hormone,” but all people have some testosterone. Normally the ovaries produce very small amounts, but in PCOS, they make more.
Every month multiple follicles grows from the ovary, they make many hormones, but eventually only follicle gets released known as the egg. This is called “ovulation.”
But in people with PCOS, the ovary makes many small follicles instead of one big one. Hormone levels can get out of balance. And ovulation doesn’t happen every month the way it is supposed to happen.
There are two main causes for this:
- Abnormal GnRH(a hormone controlling FSH/LH hormone that help in egg maturation) pulse
- Insulin resistance
