There is no evidence that marijuana impairs male reproductive functioning.
The Jamaican and Costa Rican field studies detected no differences in hormone levels between marijuana users and non-users.
In epidemiological surveys of marijuana users, no problems with fertility have emerged as important.
In 1974, researchers reported diminished testosterone, reduced sexual function and abnormal sperm cells in males identified as chronic marijuana users. 34 In a laboratory study, the same researchers reported an acute decrease in testosterone, but no chronic effect after nine weeks of smoking; they did not evaluate sperm volume or quality. 35 In other laboratory studies, researchers have been generally unable to replicate these findings, 36 although by administering very high THC doses - up to 20 cigarettes per day for 30 days - one study found a slight decrease in sperm concentrations. 37 In all studies, test results remained within normal ranges and probably would not have affected actual fertility.
Severe adverse consequences have also been produced in male laboratory animals, although only with extremely high daily THC doses. 38
More importantly, in both the human and animal laboratory studies, all observed changes were reversed once THC administration was halted.
