Abstract:
OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.
METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.
RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).
CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.
