Abstract

STUDY OBJECTIVE:

We sought to compare the outcomes of in vitro fertilization (IVF) treatments in women with infertility-associated deep infiltrative endometriosis (DIE) who underwent extensive laparoscopic excision of endometriosis before IVF with those who underwent IVF only.

DESIGN:

Prospective cohort study.

SETTING:

Infertility clinic and private hospital in São Paulo, Brazil.

PATIENTS:

A total of 179 infertile patients younger than 38 years had symptoms and/or signs of endometriosis and sonographic images suggestive of DIE.

INTERVENTIONS:

After thorough counseling, 179 women were invited to participate in a prospective cohort study with 2 treatment options: IVF without undergoing laparoscopic surgery (group A, n = 105) and extensive laparoscopic excision of DIE before IVF (group B, n = 64). Ten women were lost to follow-up. The IVF outcomes were compared between the 2 groups.

MEASUREMENTS AND MAIN RESULTS:

In group B, patients had 5 +/- 2 (mean +/- SD) DIE lesions excised during laparoscopy. Patient characteristics in groups A and B, respectively, were: age (32 +/- 3 vs 32 +/- 3 years, p = .94), infertility duration (29 +/- 20 vs 27 +/- 17 months, p = .45), day-3 serum follicle-stimulating hormone levels (5.6 +/- 2.5 vs 5.9 +/- 2.5 IU/L, p = .50), and previous IVF attempts (1 +/- 1 vs 2 +/- 1, p = .01). The IVF outcomes differed between groups A and B, respectively, with regard to total dose of recombinant follicle-stimulating hormone required to accomplish ovulation induction (2380 +/- 911 vs 2542 +/- 1012 IU, p = .01), number of oocytes retrieved (10 +/- 5 vs 9 +/- 5, p = .04), and pregnancy rates (24% vs 41%, p = .004), but not number of embryos transferred (3 +/- 1 vs 3 +/- 1, p = 1). The odds ratio of achieving a pregnancy were 2.45 times greater in group B than in group A.

CONCLUSION:

Extensive laparoscopic excision of DIE significantly improved IVF pregnancy rates of women with infertility-associated DIE.
