What is Hypothalamic Amenorrhea?

Hypothalamic Amenorrhea (HA) in brief is a condition in which menstruation stops for several months due to a problem involving the hypothalamus. Hormones obviously play a crucial role in every step of a successful pregnancy. The hypothalamus in the center of the brain controls reproduction. It produces the hormone, gonadotropin releasing hormone (GnRH). GnRH signals the production of other hormones needed for the egg to mature and for ovulation, such as follicle stimulating hormone (FSH) and after ovulation, progesterone luteinizing hormone (LH). In turn, FSH and LH signal the ovaries to produce estrogen. Estrogen thins the cervical mucus and, along with progesterone, prepares the uterus for a fertilized egg. Sometimes the hypothalamus stops producing GnRH, which in turn, will reduce the amount of other hormones produced (FSH, LH, and estrogen). Ovulation and menstruation stop, resulting in infertility.

So this is what the science behind my condition and how my brain doesn't work correctly to produce the hormones needed to have a cycle. A fun fact about this condition is that only 5% of the population has this condition but it is treatable. So at least I have that going for me even if I am in the minority!
