Absence of sperm with rapid motility is not detrimental to IVF outcome measures when ICSI is used.
The objective of the current study was to investigate the association between rapid motility of sperm and IVF outcome when ICSI is used for insemination of oocytes. The first IVF cycle of women up to age 42 were evaluated. Patients were classified into groups by the presence/absence of sperm with rapid motility ("A" sperm) in the specimen before and after sperm preparation. Group 1 had 0% A sperm prewash and 0% A postwash (n = 45); Group 2 had 0% A sperm prewash but some A sperm postwash (n = 47); Group 3 had A sperm both pre and postwash (n = 141). Statistical analysis demonstrated no difference in the fertilization, PRs, or implantation rates in the three groups. These data suggest that absence of sperm with rapid motility postseparation of sperm from seminal plasma is not detrimental to IVF outcome when ICSI is used for insemination.
