Value of sperm morphology assessed by strict criteria for prediction of the outcome of artificial (intrauterine) insemination.

The purpose of this study was to investigate the relationship between sperm parameters and the outcome of artificial (intrauterine) insemination (IUI). One hundred and twenty-six patients undergoing 395 consecutive IUI cycles in a 1-year period in our institution were studied. In all cases, controlled ovarian stimulation and hCG-timed IUI were performed, followed by progesterone supplementation of the luteal phase.

Impact of cryopreservation on spermatozoa from infertile men: implications for artificial insemination.

The objective of this study was to evaluate the effect of cryopreservation-thawing on the quality of sperm from men with subfertile semen parameters. Twenty-seven patients with teratozoospermia, six of whom also had asthenozoospermia, were studied and their sperm parameters were compared to those of fertile donors (n = 71) in their fresh, post-thaw, and washed samples. After thawing, the percentage decrease in motility was significantly greater in patients than in donors, but the motility yield (post-thaw motility/prethaw motility) reached an average of 58% in the patient group vs.
