Does seminal fluid decrease with age? Exploring the science behind male reproductive aging

According to a 2024 study, older men had significantly lower semen volume, with a mean of 2.6 ml for those over 51, compared to 3.6 ml for men aged 18–30. The evidence suggests that, yes, seminal fluid decreases with age, particularly after the age of 45. This gradual decline is part of a broader shift in male reproductive health influenced by changes in hormonal balance and accessory gland function.
