Live Science: “Men Who Smoke Pot May Have Lower Sperm Count”

From Live Science:

“In the absence of a larger, definitive study, the best advice would be to assume these changes are going to be there [in sperm],” said lead author Susan Murphy, the chief of the Division of Reproductive Sciences in the Department of Obstetrics and Gynecology at Duke University Medical Center in North Carolina.

Tim Jenkins, an epigenetics and male fertility expert at the University of Utah School of Medicine, who was not involved in the study, told Live Science that “despite the limited sample size in this study, a real strength are the animal data which comport remarkably well with the human data,” which “makes the results significantly more convincing.”
