Human menopausal gonadotrophin (HMG) is obtained from the urine of postmenopausal women. It possesses hormonal effects similar to those of the naturally occurring hormones in the human brain (anteropituitary hormones). The administration of Menogon stimulates the production of certain endogenous substances (sexual steroids) in the sexual organs. In males and females, Menogon has a hormonal effect on the reproductive glands, in females on the fallopian tubes (ovaries), and in males on the testes.
In females, Menogon promotes an increase in the growing follicles in the ovary and stimulates their development.
In males, Menogon promotes the formation of the male sexual hormone (testosterone) and the development of sperm.
Menogon can be used together with Choragon (human chorionic gonadotrophin, hCG) in females who desire children to induce ovulation after stimulating follicle growth, in males to stimulate the development of sperm.
