But the new result agrees with findings in associate earlier study from identical cluster of researchers. therein study, men UN agency rumored ever having preserved marijuana had higher spermatozoan counts, on average, than those that had ne'er used the drug.
Still, the new findings do not mean that men ought to begin smoking marijuana to spice up their fertility. solely alittle variety of participants aforesaid they preserved marijuana round the time of their fertility treatments, that reduces the strength of the results. At most, they recommend that marijuana might not have a harmful result on men's room fertility, the authors aforesaid. On the opposite hand, the researchers do not assume their findings ought to be taken as proof that marijuana features a helpful result for men undergoing fertility treatment.
There is associate imperative would like for "additional analysis to clarify the role of marijuana use on human replica and on the offspring's health," the authors over.
Despite the growing use and legitimation of marijuana round the world, scientists apprehend very little regarding however the drug impacts fertility. And few studies have enclosed each men and girls.
In the new study, the researchers analyzed data from two hundred couples UN agency underwent fertility treatment at Massachusetts General Hospital between 2005 and 2017. The researchers additionally enclosed knowledge from a further 220 girls UN agency underwent fertility treatment, however didn't have a partner within the study.
Participants were asked whether or not they were presently exploitation marijuana, had used the drug within the past or had ne'er used it.
Overall, a quarter mile of the ladies and sixty one of the lads within the study rumored that they had preserved marijuana at some purpose in their lives. however simply twelve girls (3%) and twenty three men (12%) within the study aforesaid they were presently exploitation marjuana.
Among the little variety of girls UN agency aforesaid they presently preserved marijuana and have become pregnant throughout the study, over five hundredth toughened a gestation loss, compared with simply twenty sixth of the ladies UN agency were past marijuana users or UN agency had ne'er used the drug.

On the opposite hand, among couples whose male partner was a current marijuana user, forty eighth eventually had a nascence, compared with simply twenty ninth of couples UN agencyse male partner was a past marijuana user or who had ne'er used it.

More and a lot of patients area unit asking regarding the procreative effects of marijuana, however doctors have had few studies to share once advising patients.
"At least weekly, I actually have patients asking Maine regarding the results of marijauna on male fertility," said Dr. physicist Parekh, a medical specialist specializing in male fertility and men's room health at the Cleveland Clinic's Glickman Urological Institute. "There simply is not a good answer we will offer them nevertheless."
In this sense, the new study is "a step within the right direction," Parekh told Live Science.
However, the new study by itself is not enough for doctors to suggest that men smoke marijuana before fertility treatment.
Parekh noted that, with solely twenty three men within the study coverage current use of marijuana, "It's exhausting to create that huge of an announcement locution marijuana goes to enhance success rates" with fertility treatment.
But Parekh in agreement with the authors that, instead of showing a profit as such, the study suggests that smoking marijuana might not hurt the possibilities of success with fertility treatment once the male partner uses it.
The study authors note that their work enclosed couples undergoing fertility treatment, then the findings might not apply to couples making an attempt to conceive while not medical help. Indeed, Parekh noted that some kinds of IVF use solely one spermatozoan to fertilize associate egg, then with these treatments, a man's spermatozoan count is not sometimes a giant deal. however once couples are attempting to conceive naturally, spermatozoan count matters a lot of.
In addition, the new study solely asked regarding marijuana smoking and not alternative kinds of marijuana use.
More sturdy studies area unit currently required to seem at this issue, aforesaid Parekh, and he expects to ascertain a lot of analysis during this space within the returning years.
