Motility longevity of sperm samples processed for intrauterine insemination.
This study demonstrates that sperm from men with male factor infertility and sperm obtained by electroejaculation have reduced motility longevity when compared with normal specimens. After 24 hours, normal samples lost only 34% of initial motility, whereas male factor patients lost 48%, and electroejaculation patients dropped 66%. Based on these data and previous clinical studies of insemination timing, it is recommended that sperm retrieval and artificial insemination for male factor infertility, especially when electroejaculation is necessary, be performed 24 to 36 hours after urinary detection of the LH surge or as close to the time of ovulation as possible.
