Medical considerations

According to a 1969 study, there is a decrease in sperm concentration as men age. The study reported that 90% of seminiferous tubules in men in their 20s and 30s contained spermatids, whereas men in their 40s and 50s had spermatids in 50% of their seminiferous tubules. In the study, only 10% of seminiferous tubules from men aged > 80 years contained spermatids.
