2 Clinical Trials for Various Conditions
The purpose of this study is to understand the direct effects of cannabis on male reproductive functions. The investigators plan to conduct a double-blind, placebo-controlled clinical trial to examine both the chronic and acute effects of cannabis use on male reproductive functions. Specifically, the investigators will examine the dose-dependent effects of acute cannabis use on male reproductive parameters, including sperm counts, motility, morphology, and testosterone levels, as well as sperm epimutations. Participants \[cannabis users will be randomly assigned to 1) non-vaping, 2) placebo (vaping without cannabis), and 2 doses of cannabis, 3) 20 and 4) 40mg of THC in cannabis flower obtained from the NIDA drug supply\], and 5) non-cannabis users (naïve control, no cannabis or placebo exposure). Participants will provide surveys (cannabis use and sexual functioning and satisfaction etc.), peripheral blood, and semen.
The purpose of the study is to collate local information to better understand the motivations, accessibility and frequency of assisted reproductive technology (ART) use in the community.
