Can running cause male infertility problems?
OVERTRAINING AND MALE INFERTILITY
Q: I am a 37 year old male runner with fertility problems. 85% of my sperm are abnormal and their mobility is poor. Last fall I was running between 50 and 70 miles per week; I am presently down to 30. Could my distance running be a contributing factor?
