Clinical trials: Hyperandrogenemia
Hyperandrogenemia, Polycystic Ovary Syndrome
Assessment of Sensitivity of the Hypothalamic GnRH Pulse Generator to Estradiol and Progesterone Inhibition
Gonadotropin-releasing hormone (GnRH) is a hormone that regulates the ability of the pituitary to secrete two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

PCOS
Theca Cell Function in Adolescents With Polycystic Ovary Syndrome (PCOS)
In women with polycystic ovary syndrome (PCOS), the cardinal physiological abnormality is excessive ovarian androgen production marked by increased serum testosterone (T) and androstenedione (A) levels.
