[Endometriosis and fertility: Results after surgery and Assisted Reproductive Technology (ART)]

To evaluate fertility outcomes after laparoscopic and ART management of endometriosis in an infertile population.

Retrospective analysis including 79 infertile patients treated by laparoscopic surgery. Fertility was studied in relation to pregnancy's mode (spontaneous or ART) and to endometriosis stages (rAFS).

After laparoscopy, 8.9% of patients had a spontaneous pregnancy. IIU led to a cumulative rate of pregnant women of 21.5%. Then after laparoscopy, IIU and IVF, 68.4% of patients were pregnant. The average delay was 460 days between laparoscopy and spontaneous pregnancy, 271 days between surgery and IIU pregnancy and 600 days between surgery and IVF pregnancy. Among women with stages I-II endometriosis (62 cases), 11.3% patients obtained a spontaneous pregnancy, the cumulative rate of pregnant women after laparoscopy and IIU was 25,8%. After laparoscopy, IIU and IVF, 66.1% of patients were pregnant. The average post-surgical time to spontaneous pregnancy was 460 days. The average delay between surgery and IIU pregnancy was 279 days and 589 days between surgery and IVF pregnancy. In case of stages III-IV (17 patients), 76.4% of pregnancies were obtained. No spontaneous pregnancy was observed. 94.1% of patients were treated with IVF, leading to a global rate of pregnancy of 70.5%. The average delay between surgery and IVF pregnancy was 563 days.

With a combination of surgery and ART, two-third of patients were pregnant with an average time between surgery and pregnancy of less than two years. This combination (surgery and ART) increases the chances of becoming pregnant. At the moment, the delay between surgery and ART needs to be established.
