Abstract:
This study demonstrates a statistically significant decrease in semen volume, sperm concentration, and sperm motility in samples obtained on the 2nd day of consecutive day inseminations in an IUI program. This diminution in semen characteristics persists despite sperm washing. The effects of a second ejaculation on semen parameters in oligospermic and asthenospermic men were mixed. Thus, in general, sperm-washing procedures cannot overcome the natural reduction in semen quality produced by frequent ejaculations. Clinicians may wish to use this information in timing IUI cycle inseminations.
