The study , which was published Aug. 14 in the journalHuman Reproduction , call for several hundred couples undergo fecundity treatment within vitro impregnation ( IVF ) . The researchers found that womanhood who reported currently using marijuana had a higher likeliness ofpregnancy release , compared with women who did n’t use ganja .

But the new result agrees with findings in an earlier subject area from the same group of researchers . In that study , men who report ever having smoke marijuanahad higher sperm counts , on mediocre , than those who had never used the drug .
Still , the new findings do n’t intend that men should depart fume marijuana toboost their fertility . Only a little number of participants say they smoke marijuana around the time of their fecundity treatments , which reduces the enduringness of the results . At most , they intimate that marijuana may not have a harmful consequence on man ’s fertility , the source said . On the other hand , the researchers do n’t think their findings should be taken as evidence that marijuana has a beneficial effect for hands undergoingfertility handling .
There is an urgent demand for " additional research to clarify the role of marijuana use on human replication and on the offspring ’s health , " the author concluded .
Despite the farm exercise andlegalization of marijuanaaround the world , scientist cognise little about how the drug impacts fertility . And few studies have included both Man and women .
In the Modern written report , the researcher analyze data from 200 couples who underwent fertility handling at Massachusetts General Hospital between 2005 and 2017 . The researchers also included data from an additional 220 women who underwent rankness discussion , but did not have a partner in the study .
participant were ask whether they were presently using marijuana , had used the drug in the yesteryear or had never used it .
Overall , 44 % of the woman and 61 % of the men in the study reported they hadsmoked marijuanaat some pointedness in their lives . But just 12 woman ( 3 % ) and 23 valet de chambre ( 12 % ) in the study said they were currently using marjuana .
Among the small number of cleaning woman who said they currently smoke marijuana and became pregnant during the study , more than 50 % know a pregnancy loss , compared with just 26 % of the women who were retiring marijuana users or who had never used the drug .
This finding hint that marijuana use among charwoman " may be related to worse sterility intervention upshot , " the authors said . But they caution that since very few women in the study were current marijuana users , it ’s possible that this finding was due to chance .
On the other handwriting , among couples whose male better half was a current marijuana user , 48 % finally had a springy birth , compare with just 29 % of couples whose male cooperator was a retiring marijuana substance abuser or who had never used it . The link held even after the researchers take in into explanation some factors that could dissemble birth rate , including the player ' years , ethnicity , body mass indicator ( BMI ) , tobacco smoke history , coffee consumption , alcohol usage and cocaine use .
More and more patients are inquire about the procreative effects of marijuana , but Dr. have had few field of study to partake when notify patients .
" At least hebdomadally , I have affected role asking me about the effects of marijauna on manly fertility , " said Dr. Neel Parekh , a urologist specializing inmale fertilityand men ’s health at the Cleveland Clinic ’s Glickman Urological & Kidney Institute . " There just is n’t a expectant answer we can give them yet . "
In this good sense , the raw study is " a tone in the right guidance , " Parekh told Live Science .
However , the new study by itself is n’t enough for doctors to recommend that men smoke marijuana prior to fertility treatment .
Parekh noted that , with only 23 men in the subject area cover current use of marijuana , " It ’s hard to make that enceinte of a statement saying marijuana is go to improve success pace " with rankness treatment .
But Parekh match with the author that , rather than show a welfare per se , the study hint that smoke marijuana may not suffer the probability of success with fertility discussion when the male partner uses it .
The bailiwick authors note that their study let in couples undergoing birth rate treatment , and so the findings may not apply to span judge to conceive without aesculapian assistance . Indeed , Parekh noted that some forms of IVF manipulation only a unmarried sperm cell to fertilise an egg , and so with these treatment , a man’ssperm countisn’t usually a big flock . But when couples are try out to conceive naturally , spermatozoon count matters more .
In summation , the young work only asked about marijuana smoking and not other form of marijuana use .
More robust subject are now needed to look at this issue , said Parekh , and he expects to see more research in this area in the come years .
