In polycystic ovary syndrome, “poly” means many, and “cystic” refers to cysts.
One of these gonadotropins is the luteinizing hormone, or LH.
The other is the follicle-stimulating hormone, or FSH.
LH and FSH travel to the follicles in the ovaries.
The follicles are small clusters of theca and granulosa cells that protect the developing oocyte, or egg.
The theca cells develop LH receptors which allow them to bind LH, and in response they secrete a hormone called androstenedione.
Granulosa cells develop FSH receptors, which allow them to bind to FSH and produce an enzyme called aromatase, which converts the androstenedione into 17β-estradiol - a member of the estrogen family.
Polycystic ovary syndrome or just PCOS, refers to a set of symptoms due to excessive androgen production in women. Signs and symptoms of PCOS include irregular or no menstrual periods, heavy periods, excess body and facial hair, acne, pelvic pain, trouble getting pregnant, and patches of thick, darker, velvety skin. Associated conditions include type 2 diabetes, obesity, obstructive sleep apnea, heart disease, mood disorders, and endometrial cancer. Management for PCOS may involve lifestyle modifications such as diet and exercise, hormone therapy, and medications.
