Sexual secretions
Semen changed consistency

Alice, My semen has changed over the past year from a thick milky consistency to an almost clear water ejaculate. What are likely causes of this? My doctor was clueless. -- Watery cum

 

Dear Watery cum,
There are many reasons why semen can alter its consistency. The most common antecedents are changes in diet, change in exercise, or a change in tightness of clothing around the genitals (tight pants or briefs). Exercising and wearing tight clothing can increase the heat of the scrotum, changing sperm motility and potentially, semen consistency as well. If you were also experiencing a discharge, or pain with urination then it would advisable to get tested for sexually transmitted infections. However, change in semen consistency on its own is not considered abnormal or dangerous. Keep talking to your physician if you continue to be concerned.
