Abstract
Objective: To study the velocity characteristics of sperm movement by CASA machine. Materials and Method: Using description method, we analyse speed of 136 semen samples in male infertilities. Results: (i) In the primary infertile males group: the rate of patients with mobile speed of sperm <30µm/s is 3.64%, > 30-40µm/s is 25.45%, > 40-50µm/s is 50.91% and > 50 µm/s is 20%. These indicators in the secondary infertile males group as follow: 6.17%, 18.52%, 51.85 %, and 23.46%; (ii) The rate of samples with sperm progressive motility ≥ 25% in primary and secondary infertilities was no statistically significant difference. Discussion: using the rate of sperm progressive motility, we can’t identify the different between primary and secondary infertility, however speed of sperms were different. Conclusion: Measuring the speed of sperm provide the characteristics of male infertility. Key words: Male infertility, sperm, sperm motility, primary infertility, secondary infertility.
