No.
Yes, but they have a lower sperm count.
There is limited research on this topic, but some studies suggest that THC, the psychoactive component of marijuana, can be found in semen. However, it is unclear how much THC would need to be present to affect fertility or the health of a fetus. More research is needed to fully understand the potential effects of marijuana use on sperm and pregnancy.
Marijuana can be found worldwide.
No. It is proven that marijuana decrease sperm count, but it is a very light decrease, over long periods of time.
A recent study, conducted at the University of Buffalo in New York in 1998, reports that marijuana affects sperm function by compromising its ability to get to and fertilize the egg. The study attributes the cause to cannabinoids (compounds found in marijuana). These cannabinoids are similar to natural body substances called anandamides. University scientists believe that anandamides function in helping sperm get to and fertilize the egg. It is believed that marijuana cannabinoids are chemically similar to anandamides. Receptors meant to respond to anadamines may also respond to cannabinoids. By responding to the wrong body substance successful fertilizing of the egg may not occur.
Marijuana does lower sperm count. It also lowers seminal fluid and decreases the coordination of the sperms motility.
Contrary to popular belief, cannabis actually slightly increases your sperm count.
Smoking weed has no bearing on how "strong" a mans sperm is.
THC is the psychoactive substance found in marijuana.
