Abstract

Objective: The purpose of this observational study was to determine whether semen parameters (concentration, motility) were affected by the interval between the onset of postwash sperm incubation and intrauterine insemination (IUI) time.

Material and methods: Semen specimens of 100 normozoospermic men collected at the clinic were allowed 20 minutes for liquefaction at room temperature. Semen samples were subjected to both macroscopic and microscopic examinations. After centrifugation in a density gradient column and sperm-washing medium, the samples were kept in an incubator. After 30 minutes, 60 minutes, and 120 minutes, the concentration and motility were recorded.

Results: According the results of the Bonferroni post hoc test, there were significant differences in values of mean sperm count, percent progressive sperm motility, and total motile sperm count between 30 minutes and 120 minutes (p=0.000, p=0.000, and p=0.000) and between 60 minutes and 120 minutes (p=0.000, p=0.000, and p=0.001), but there was no significant difference between 30 minutes and 60 minutes (p=1, p=0.173, and p=1).

Conclusion: This study demonstrated that sperm parameters are negatively affected from prolonged incubation time. A maximum 60-minute limit of the interval between the onset of postwash sperm incubation and IUI time may increase pregnancy rates.

Keywords: IUI time; semen parameters; sperm wash.
