Common side effects of the hypoestrogenic state include hot flashes, vaginal dryness, decreased libido, insomnia, breast tenderness, depression, headaches, and transient menstruation. In addition, GnRH analog treatment for the recommended six month period causes loss in bone density and total body calcium. GnRH analogs are effective in reducing the size of endometriotic implants following treatment. The recurrence rate over five years ranges from 37 percent in patients with mild disease to 74 percent in those with severe disease. GnRH analogs are as effective as other medical therapy in relieving pain symptoms, but, similar to other drug treatments, they do not enhance fertility.

Oral Contraceptive Pills

Oral contraceptive pills (OCPs) suppress LH and FSH and prevent ovulation. They also have direct effects on endometrial tissue.
