Marijuana Moment reports….Here’s a question few may have thought to ask: Can THC be detected in semen?
Umm we wonder why it isn’t a regularly asked question ! But anyway….
Many people have had to take a urine test for cannabis, perhaps as a job requirement. Using the popular procedure, marijuana metabolites can in some cases be detected for weeks after a person’s last use. But here’s a question few may have thought to ask: Can THC be detected in semen?
According to a new study by a team of Harvard Medical School researchers, the answer is yes—at least sometimes. In a study of 12 participants who regularly consumed marijuana by inhalation, the researchers were able to detect delta-9 THC, the main psychoactive ingredient in cannabis, in two subjects’ semen samples. And at least one metabolite of THC—what’s left over after the body processes the compound—could be detected in all samples capable of being analyzed. “Two semen samples,” the report says, “had insufficient volume to be analyzed.”
Why the focus on THC in semen? In a word, pregnancy. Men of reproductive age, the study’s authors note, “are the most prevalent consumers of marijuana, with 19.4% of men in the USA reporting use.” A 2018 study cited by the authors found that 16.5 percent of men and 11.5 percent of women reported using marijuana while attempting to conceive.
How exactly THC affects reproductive systems and childhood development are questions the Harvard authors don’t attempt to answer in the study. The primary goal of the proof-of-concept research, they explain, “was to determine whether THC can cross the blood-testis barrier.” On that front, they appear to have succeeded.
“In the setting of a growing repository of data surrounding the effects of the endocannabinoid system in the regulation and maintenance of fertility and early pregnancy,” the study says, “ours is the first report that the exogenous cannabinoid THC can be detected in any human reproductive matrix.”
Because of the interest in whether THC could be detected at all, researchers focused on regular, long-term marijuana consumers. All participants indicated they had used the drug between 25 and 30 days of the last month, and most said they had been regular consumers for at least five years. “Consequently,” the team said, “our study findings cannot be generalized to include ever users, light, or moderate users of marijuana.”
Of the two participants whose semen contained detectable levels of THC itself, samples contained 0.97 nanograms per milliliter and 0.87 ng/mL.
