Endometriosis and infertility
Surgery is more effective for infertility than medicinal intervention in endometriosis. One study has shown that surgical treatment of endometriosis approximately doubles the fecundity (pregnancy rate). The use of medical suppression after surgery for minimal/mild endometriosis has not shown benefits for patients with infertility. Use of fertility medication that stimulates ovulation (clomiphene citrate, gonadotropins) combined with intrauterine insemination (IUI) enhances fertility in these patients.
SGK
Deregulated expression of SGK1 in the endometrium has been implicated in cases of infertility or recurrent miscarriage in humans, and SGK1 expression in the endometrium also affects fertility in mice.
