Impact of laparoscopic ovarian drilling on the pregnancy rate in clomiphene resistant polycystic ovarian syndrome patients undergoing in vitro fertilization: randomized controlled trial
The main objective of this randomized controlled trial was to study the impact of LOD on the pregnancy rate after ICSI ET in PCOS. The study was conducted in Egypt in the period 2015 2017 and included 212 clomiphene resistant PCOS patients, with at least 1 year infertility. The study group was the drilling group who underwent LOD and then ICSI ET, while the control group did not undergo LOD but directly proceeded to ICSI ET. The primary outcome was the clinical pregnancy rate per ET cycle. The baseline characteristics and hormonal profiles were comparable (p 0.05) between the two groups. Ovarian stimulation days were (p 0.001) higher in the drilling group. Endometrial thickness, estradiol at triggering day, and the number of oocytes retrieved were (p 0.001) lower in the drilling group. The numbers of embryos transferred were not different (p 0.05) The clinical pregnancy rate per ET cycle was higher in the drilling group (51% than in the control group (37% (p 0.046) Multiple pregnancies were not significantly (p 0.265) different between groups. The rate of OHSS was (p 0.046) higher in the control group. Coasting was (p 0.001) higher in the control group (18% compared to the drilling group (2% Laparoscopic ovarian drilling for PCOS patients before ICSI ET improves the clinical pregnancy rate with a reduction of OHSS.
