Dear Aspirant,

Hormonal interaction between the hypothalamus, anterior pituitary gland, and ovaries regulates the female reproductive system. The hypothalamus secretes a small peptide, gonadotropin-releasing hormone (GnRH), also known as luteinizing hormone–releasing hormone.

In females, the main hormones are estrogen and progesterone. The production of these hormones mainly occurs in the ovaries, adrenal glands, and, during pregnancy, the placenta. Female hormones also have an influence on body weight, hair growth, and bone and muscle growth
