Objectives: Laparoscopy is considered the gold standard for treatment of endometriosis. In vitro fertilization and embryo transfer (IVF-ET) is often used to treat women with infertility associated with endometriosis. The objective of the study was to evaluate the pregnancy rate after surgical treatment and to assess whether a combined approach with laparoscopic surgery followed by IVF-ET can improve the "overall" pregnancy rate.
Study design: A retrospective observational study was carried out on 107 infertile patients who underwent laparoscopic surgery for endometriosis and came at follow-up for a period of time between 1 and 11 years. Sixty-seven patients who did not become pregnant after surgery subsequently underwent IVF-ET.
Results: The pregnancy rate achieved after the integrated laparoscopy-IVF approach was 56.1%. The pregnancy rate after surgery, was significantly lower (37.4%). The fecundity rate for spontaneous conceptions within 6 months of laparoscopy (23.2%) was significantly higher (P<0.05) than for the following intervals. The cumulative fecundity in women older than 35 years was significantly lower than in younger women.
Conclusions: In patients with endometriosis-associated infertility, surgery followed by IVF-ET is more effective than surgery alone. When patients fail to conceive spontaneously, after a maximum of 1 year from laparoscopic surgery, IVF should be suggested.
