Influence of multiple transrectal electroejaculations on semen parameters and intracytoplasmic sperm injection outcome.

To compare semen parameters and intracytoplasmic sperm injection (ICSI) outcome in spinal cord-injured subjects who underwent single (group 1) or multiple (group 2) electroejaculations before ICSI.Prospective, randomized, controlled study.Department of gynecology, obstetrics, and pediatric science in a reproductive medicine unit at a major Italian university.Thirty-four healthy women with a male partner with SCI who were seeking assisted reproduction services.Transrectal electroejaculation, controlled ovarian hyperstimulation, and ICSI.Sperm concentration, morphology, and motility and fertilization and pregnancy rates after ICSI.Sperm was successfully retrieved in 94.1\% of cases. In male subjects who underwent multiple electroejaculations, statistically significant improvements in sperm concentration and total sperm motility rate were observed. The overall fertilization rate was 63.6\%. The number of oocytes retrieved and injected was comparable between the two groups. A total of nine clinical pregnancies were achieved. The pregnancy rate was statistically significantly higher in group 2 (n = 6/16; 37.5\%) than in group 1 (n = 3/16; 18.75\%).These data suggest that multiple electroejaculation has a positive effect on semen parameters and ICSI outcome
