A Comparison of Sperm Motility Between Fertile and Infertile Males
Background: To determine the sperm motility of proven fertile males and compare this with that of infertile males. Methods: The study design was cross-sectional comparative and was carried out at Islamic International Medical College Rawalpindi and its attached Railway hospital and Islamabad Clinic Serving Infertile Couples Islamabad, from June 2005 to July 2006. Fifty healthy fertile males were selected and their sperm motility was determined with the latest Makler’s chamber, while another 50 infertile males were recruited as controls. The sampling technique used was convenience non-probability. Inclusion criterion for proven fertile males was pregnancy achieved within one year of marriage with successful coituses. In case of infertile males it was failure to achieve pregnancy without the use of assisted reproductive techniques, with no infertility factors in the female partner. The semen samples were obtained at the laboratory after 3 to 4 days of sexual abstinence with clear written and oral instructions given to the subjects before the collection of the sample. Results: The infertile group was found to be statistically older than the proven fertile group i.e. (36.60 versus 31.32 years). Proven fertile group showed significantly higher motility (60.32 ± 10.80%) and progressive motility (14.32 ± 8.31%) than the infertile male group. Conclusion: Sperm motility is useful in in-vivo situation to find males having a greater possibility of infertility problem. More studies with a larger sample size are required to establish a cut-off value in the local population.
