Abstract
- This retrospective study was designed to determine whether there is any difference between short and long protocol ovulation induction with Gonadotropin Releasing Hormone agonist (GnRHa) and gonadotropins used in Assisted Reproductive Technology (ART) applications according to the number of retrieved oocytes, oocyte maturity, fertilization rates, embryo quality and the outcome of pregnancies. 240 cycles consisting of in vitro fertilization (IVF) cycles without andrologic factor and intracytoplasmic sperm injection (ICSI) cycles were evaluated. 112 cycles which were induced by short protocol GnRHa and Follicle Stimulating Hormone (FSH) + Human Menopausal Gonadotropin (HMG) combinations and 128 cycles which were induced by long protocol GnRHa and FSH + HMG combinations were compared according to the number of retrieved oocytes, cancellation rate of cycles, oocyte maturity, fertilization rates, embryo quality and pregnancy rates. The cancellation rate for short protocol cycles were found to be significantly higher than those with long protocol. The number of retrieved oocytes, mature oocytes and fertilized oocytes were also found significantly lower. The quality of embryos did not show any significant difference between these groups. The clinical pregnancy rates were evidently found to be high in the long protocol cycles. As a conclusion we have found that while the number of retrieved oocytes, mature oocytes, fertilized oocytes and clinical pregnancy rates were increasing, the cancellation rate of cycles were decreasing significantly in ART cycles induced by long protocol.
