Abstract:Objective To examine the outcome of in vitro fertilization (IVF) after long-term pituitary down-regulation for women with moderate or severe endometriosis and normal ovarian reserve. Methods A retrospective analysis was performed on 95 prolonged protocol IVF cycles for women with moderate or severe endometriosis and normal ovarian reserve. A total of 1654 long protocol IVF-ET cycles performed during the same period with tubal infertility and normal ovarian reserve were considered as controls. Results The doses of gonadotropins were significantly higher in the group with endometriosis than in the tubal factor group (44.4±9.9 U vs. 25.5±7.1 U, P<0.05). The number of retrieved oocytes and the number of transferable embryos were significantly lower in the endometriosis group than in the tubal factor group (10.4±4.8 vs. 11.5±4.3, and 3.7±2.3 vs. 5.3±3.2, respectively). The levels of luteinizing hormone on gonadotropins (Gn) launch day and hCG injection day were significantly lower in the endometriosis group than in the tubal factor group (0.46±0.26 U/L vs. 1.01±0.56 U/L, and 0.47±0.26 U/L vs. 1.38±4.75 U/L, respectively). The clinical pregnancy (69.2% vs. 70.2%), implantation (47.6% vs. 51.5%), miscarriage (14.3% vs. 9.7%) and delivery rate (58.2% vs. 61.5%) were comparable between the two groups. Conclusion The outcomes of IVF conducted with prolonged GnRH-a protocol on women with moderate or severe endometriosis were good if the women had normal ovarian reserve. However, ovarian response decreased in the endometriosis group after long-term pituitary down-regulation.
