Does marijuana cause fertility problems?

David G. Ostrow (Medical Marijuana Doctor) gives expert video advice on: What are some potential side effects from using medical marijuana?; Is marijuana a gateway drug?; Does marijuana cause brain damage? and more...

Again, there were a number of studies published in the seventies and the early eighties about marijuana and fertility problems. I do not think those studies have held up to the test of time. And I am not aware of any good research that indicates that marijuana causes fertility problems in humans.
