Abstract

Proper collections of human ejaculates are necessary for semen analysis and infertility treatment purposes. The objective of this study was to assess the seminal characteristics of ejaculates collected by patients via masturbation and coitus interruptus. Thirty individuals produced one sample via masturbation and one via incomplete coitus during a 3-days interval. The semen parameters were compared and analyzed with student t-test and Nemar test. The results showed that mean values for progressive motility of spermatozoa were increased from 46.81°15.7% to 58.76°13.5% in coitus interruptus and masturbation, respectively (P<0.01). Also, the mean values for normal sperm morphology was 54.03°25.1% in coitus interruptus and 63.36°13.4% in samples collected via masturbation (P<0.01). In addition, sperm concentration was significantly improved in ejaculates collected with masturbation (P<0.05). Although, insignificant, the concentration of round cells were lower in specimens collected via masturbation than coitus interruptus. Therefore, via masturbation method, better semen characteristics were yielded which subsequently may improve the infertility treatment outcome.
