Endometriosis and assisted reproduction techniques.
Endometriosis-associated infertility is poorly treatable with various forms of surgery. Therefore, assisted reproduction techniques (ARTs), such as controlled ovarian hyperstimulation, intrauterine insemination, or in vitro fertilization, are commonly used for endometriosis-associated infertility. Endometriosis impairs the efficacy of in vitro fertilization. There is no evidence that ovulation suppression before ART would enhance the efficacy of ART. Resection of minimal/mild endometriosis and/or restoration of the normality of pelvic anatomy may enhance the efficacy of ART, but aggressive ovarian surgery should be avoided, because it reduces the ovarian reserves and the likelihood of pregnancy after ART. The outcome of ART pregnancy is not affected by the history of endometriosis, but the presence of endometrioma may predispose to preterm birth or fetal growth retardation in ART-induced pregnancies. As a whole, infertility due to endometriosis is best treated with various forms of ART, and the earlier clinicians apply these techniques, the more likely pregnancy may ensue.
