Assessment of spermatozoa in different age groups

Objective: To verify sperm disorders in different age groups through analysis of seminal fluid. Methods: The semen of 80 healthy adult men, with age range of 21 to 60 years, was studied after a five-day sexual abstinence. Volunteers were distributed into four age-groups (n = 20): 21 to 30, 31 to 40, 41 to 50 and 51 to 60 years. Rresults: No differences regarding the physical and chemical aspects of semen were found (smell, color, volume, viscosity, and pH), nor were there differences related to sperm concentration and percentage of mobile forms. Therefore, a non-significant increase in spermatozoa concentration in the semen of men aged over 41 years was observed. In the 41 to 50 years-old Group, the sperm morphology was predominantly oval (p = 0.03) and there were less tapered sperm as compared to other groups (p = 0.02). Cconclusions: It was observed that there is no reduction in sperm production up to 60 years and that there is an increase in better shape for fertility, in the age of 41 to 50 years-old.
