Not an everyday term, HCG (human chorionic gonadotropin) is produced naturally by the placenta in pregnant women.   

FOR MEN AND FOR WOMEN  

HCG is also a prescription medication for both men and women. Proven safe and highly effective for over 60 years, use of pharmaceutical grade HCG via injection by both men and women causes the body to use up its own excess fat stores while supporting healthy bodily functions. Constant doctor monitoring throughout the HCGPDX Program ensures safe administration of this powerful hormone. 

During perimenopause and menopause use of HCG tends to increase hormone production by the ovaries, therefore providing women much needed stability. Hot flashes and night sweats decrease or disappear. 

Moreover, when successful fat reduction is accomplished and administration of HCG is no longer necessary the opportunity for a "new" natural body weight set point is created through the hypothalamic gland. The hypothalamic gland controls body fat storage, so altering and then resetting this important monitoring system results in long-term weight loss success and makes future weight maintenance easier.
