Endometriosis
Surgery is more effective than medicinal intervention for addressing infertility associated with endometriosis. Surgery attempts to remove endometrial tissue and preserve the ovaries without damaging normal tissue. In-vitro fertilization (IVF) procedures are effective in improving fertility in many women with endometriosis.
Hormone replacement therapy
While combined estrogen–progestogen supplementation has been linked to an increased incidence of endometrial cancer, the specific subtype is usually stage I, or "in situ", and has extremely low morbidity and mortality, and studies in American women have shown the tumor to not have propensity for growth into the myometrium or parametrial soft tissues. When seen in the context of all cause mortality, women who take estrogen and develop endometrial cancer have higher survival rates than women who do not take hormonal therapy at all, which was due to the preventive effect of HRT on hip fractures.
