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.
Tubal factor infertility
Tubal factor infertility can be due to Chlamydia infection and testing for Chlamydia antibodies is one diagnostic tool. A "Mycoplasma genitalium" infection has also been linked to TFI. Women have difficulty getting pregnant or carrying a baby to term due to the buildup of scar tissue in the Fallopian tubes causing damage to the cilia on the epithelial cells. TFI can also be due to endometriosis.
