A team in Australia looked at 423 men aged 22 and 23 years old born to mothers between 1989 and 1991. The study measured testicular volume, semen quality, hormone production and body fat composition in these men. Looking at the results, the team found that one out of six men had sperm characteristics below normal such as low sperm volume, low sperm count and less sperm motility. Researchers found that smoking during pregnancy was associated with a lower sperm production. This study generated a new hypothesis of the possibility of men’s sperm count being related to what happens in the womb. After knowing about the effects of maternal smoking on young men’s testicular health, how would that change your counseling?
