Resumo: | Background: Knowledge regarding seminal fluid and spermatozoids in the elderly is controversial at best in the literature. The purpose of the present study was to analyze the relationship between male age and spermatozoid. Methods: The sperms of 80 healthy adult men, between 21 and 60 years of age, were studied after three to five days of sexual abstinence. Volunteers were distributed into four age groups (n = 20): 21-30, 31-40, 41-50 and 51-60 years of age.Results: No difference regarding the sperm’s physical and chemical characteristics (smell, color, volume, viscosity and pH) was found. The spermatozoid’s mobile forms showed no difference among the four groups. The concentration of spermatozoids proved to be higher in the semen of men of over 41 years of age, while in the 41 to 50 years of age group, the number of oval spermatozoids was higher (p = 0.03), with a less abnormal tapered form (p = 0.02) when compared to the other three groups. Conclusion: More normal forms of spermatozoids are found between 41 and 50 years of age. |
