Two important targets from medical treatment are: pain control and suppression of disease progress. Most of the time, the effectiveness is temporary and lasted while these drugs have been used, which is expected from the nature of endometriosis disease .Of course, there are some debts about the usefulness of pain relief agents, because 30-50% of patients feel better with placebo administration.

It must to keep in mind that those common administrated drugs couldn't help to restore the fertility potentials and in fact during their usage pregnancy cannot or should not be happened, regarding to inhibition of ovulation or teratogenic effects; of course by their administration with remission of disease (suppress the growth and activity of previous endometriotic implants) and reducing the chance of new peritoneal seeding, fertility may be preserved better; but at the end for achieving pregnancy other ways should be used.

Medical therapeutic drugs divided in two categories:


Non hormonal therapeutic options, mainly work on inflammatory and immunologic aspect of endometriosis and hormonal attempts basically deprived endometriotic implants from their nutritive substance: estrogen.
