Enhancing Sperm Quality Through Consecutive Ejaculation After Short Abstinence in Men with Low Semen Parameters Undergoing ICSI.

Background: Longer abstinence time is believed to be associated with the production of reactive oxygen species (ROS), which in excessive amounts may be detrimental to the sperm. To enhance sperm quality, multiple research studies have proposed reducing the duration of abstinence by encouraging consecutive ejaculations. This approach has been shown to improve sperm motility and morphology, which are associated with better ICSI and IUI outcomes. The purpose of the current study was to evaluate sperm quality and fertilization rate, cleavage rate, as well as embryo quality in severe oligoasthenozoospermic men using the consecutive ejaculate collected within an hour of abstinence. Methods: A prospective study was conducted at Halim Fertility Center from August 2020-April 2022, involving male partners undergoing ICSI treatment who presented with severe oligoasthenozoospermia on their previous semen analysis. The non-parametric Mann-Whitney and Wilcoxon tests were used to analyze the parameters of the groups, including characteristics of the study participants, oocytes and sperm samples, as well as the ICSI outcomes, using a significance level of 5%. Results: A statistically significant improvement in the sperm total motility was recorded in the consecutive ejaculate compared to the first (31.53±11.73% Conclusion: Consecutive ejaculates collected within an hour of the first may enhance sperm total motility, fertility, and cleavage rates in male partners with low sperm count and quality undergoing ICSI treatment.
