title: Effect of normal sperm morphology rate (NSMR) on clinical outcomes for rescue-ICSI(R-ICSI) patients.
abstract: OBJECTIVE
  To investigate whether the normal sperm morphology rate (NSMR) can affect the clinical outcomes of rescue-ICSI(R-ICSI) patients.
  
  
  METHODS
  Based on different NSMR, the patients were divided into two groups as follows: NSMR < 4% and NSMR ≥ 4% group. Main outcomes compared were fertilization, cleavage, normal fertilization, high-quality embryo, transferrable embryo, no transferrable embryo cycles, implantation, clinical pregnancy and abortion rate. Some men's and women's basic parameters were compared between pregnancy and non-pregnancy group.
  
  
  RESULTS
  The basic parameter such as female age, endometrial thickness, infertility duration, Gn administration, Gn days, basal serum FSH and basal serum E2 found no significant difference between NSMR < 4% and NSMR ≥ 4% group (p > 0.05). There was no significant difference in aspects of the number of retrieved oocytes, the number of transferred embryos, fertilization, cleavage, normal fertilization, high-quality embryo, transferrable embryo, no transferred embryo cycle, implantation, clinical pregnancy and abortion rate between two groups (p > 0.05). Between pregnancy and non-pregnancy group, we observed no significant difference in the female age, the number of retrieved oocytes, the number of high-quality embryo, the number of transferrable embryos, Gn administration, Gn does, endometrial thickness, infertility duration, basal serum FSH, basal serum E2, sperm concentration and progressively motile sperm (p > 0.05).
  
  
  CONCLUSIONS
  Teratospermia made no effect on clinical outcomes of rescue-ICSI(R-ICSI) patients.
