Objectives: To evaluate the relationship between sperm apoptosis and male infertility. Methods: Percentage of apoptotic sperm (PAS)in spermatozoa of fertile and infertile men were tested by flow cytometry (FCM). Results: Sperm apoptosis had happened in all different people. PAS in fertile and infertile group was (4.28±1.66)% and (18.67±8.55)% respectively,and difference was significant between two groups ( P 0.01).There was negative correlation between PAS and semen volume, sperm density, percentage of forward motility, percentage of normal morphology ( P 0.01). Conclusions : There was very close relationship between sperm apoptosis and male infertility. FCM used to test sperm apoptosis is rapid, accurate, objective and reliable to analyse sperm functions and male fertility.
