Pubertal timing strongly linked to men’s sexual and reproductive health

A new study finds a strong association between late onset of puberty and subsequent semen quality. This is the first study of its kind to investigate the influence of pubertal timing on male reproductive health. 1,068 healthy young Danish men participated in the study and provided information on the timing of puberty. This suggests that timing of pubertal onset may be a fundamental marker of male reproductive health. Men with a history of early puberty were shorter, had a higher BMI and were often smokers or exposed to prenatal tobacco smoke.
