Laparoscopic ovarian cystectomy for endometrioma resulted in fewer oocytes and lower fertilization rates but similar pregnancy rates in IVF treatment compared to IVF for tubal occlusion.

This retrospective study compared IVF outcomes in 95 patients treated for tubal occlusion versus 127 patients who underwent laparoscopic ovarian cystectomy for endometrioma(s) and then received IVF. The cystectomy group had fewer oocytes harvested per retrieval and a lower fertilization rate, while reporting a higher implantation rate; however, the clinical pregnancy rate did not differ significantly between groups. The main caveat is that group assignment was retrospective and outcomes were compared between different underlying infertility etiologies rather than randomized cohorts. This paper is centrally about endometriosis — it evaluates how laparoscopic ovarian cystectomy for endometrioma affects subsequent IVF and embryo transfer outcomes.

Clinical outcomes of IVF treatment were compared between two groups.ResultsMore oocytes were harvested per retrieval in Group 1 than Group 2 (p < 0.05). The fertilization rate was higher in Group 1 than Group 2 (p < 0.05). Although the implantation rate was higher in Group 2 (p < 0.05), the clinical pregnancy rate revealed no statistically significant difference between the two groups.ConclusionsWomen who received ovarian cystectomy for endometriomas have fewer oocytes harvested during IVF treatment.

Abstract

Purpose : To evaluate the effect of laparoscopic ovarian cystectomy for endometrioma on the clinical outcome of IVF treatment.

Methods

Patients who received IVF treatment were retrospectively classified into two groups. Group 1 included 95 patients who received IVF due to tubal occlusion. Group 2 included 127 patients who had received laparoscopic ovarian cystectomy for endometrioma(s) followed by IVF treatment. Clinical outcomes of IVF treatment were compared between two groups.

Results

More oocytes were harvested per retrieval in Group 1 than Group 2 (p < 0.05). The fertilization rate was higher in Group 1 than Group 2 (p < 0.05). Although the implantation rate was higher in Group 2 (p < 0.05), the clinical pregnancy rate revealed no statistically significant difference between the two groups.

Conclusions

Women who received ovarian cystectomy for endometriomas have fewer oocytes harvested during IVF treatment. However, their chance of pregnancy was comparable to patients with tubal problems who underwent IVF treatment. Similar content being viewed by others
