Lupron acts by suppressing the pituitary hormones (FSH or Follicle Stimulating Hormone and LH or Luteinizing Hormone) which are responsible for stimulating the ovaries to produce estrogen and other hormones. Chemical menopause is a term used to describe a temporary (and reversible) menopausal state created with the use of a medication called Gonadotropin Releasing Hormone Analogues (GnRHa) - a type of drug which acts on the pituitary gland in the brain to suppress ovulation and production of ovarian hormones.By fully suppressing the menstrual cycle by shutting down the ovaries, … The ability to suppress ovulation does not mean bioidentical progesterone cream is an effective form of birth control.

Why then are the hormones P and E commonly used in the Pill instead? Step 1: Before ovulation, estradiol (E2) and luteinizing hormone (LH) run the show.
