At least one local scientist is dismissing the results of a recent Harvard study which claimed that smoking marijuana may be linked to a higher sperm count.
According to noted scientist Professor Errol Morrison, ganja, when smoked, will do more harm than good as it relates to male fertility.
“(Dr) Michael Gardener has done one of the most extensive researches on that and these results showed a low sperm count and actually increases abnormal sperms,” he said. But he notd that every individual is different.
“There are men in the world who have never smoked a joint in their life and they have lots of children and there are others who smoke every day and never got their partner pregnant,” said Morrison.
Gardner is a respected lecturer in the Faculty of Medical Sciences at the University of the West Indies (UWI).
The Harvard University finding, published in the journal Human Reproduction on February 5, contradicts all conventional knowledge on how weed affects sperm.
Analysis of 1,143 semen samples from 662 men collected between 2000 and 2017 at the Fertility Clinic at Massachusetts General Hospital, showed that those who had smoked weed at some point in their life had a mean sperm concentration of 62.7 million sperm per millilitre (ml) of ejaculate, while men who had avoided marijuana entirely, had mean concentrations of 45.4 million/mL.
However, local researchers over the years have remained adamant that their research does not spell good news for ganja smokers.
A 2015 study also done at the UWI suggested that chronic marijuana use negatively affects sperm quality.
