Cannabis Use and Epigenetic Alterations in Human Male Sperm Cells

2018-08-08 16:21:13 | BioPortfolio

Summary

This is a follow-up project to a proof-of-concept study to determine if Cannabis use in male humans is associated with changes in DNA methylation profile of sperm. This proposal will examine the epigenome of sperm from men actively using Cannabis before and after a period of Cannabis abstinence. The results will be compared to control non-users.

Description

This project involves recruitment of 72 healthy males between the ages of 18 and 40 years. Forty eight of the participants will be regular cannabis users with a self-reported frequency of at least once weekly over the past 6 months, and a control group of twenty four cannabis non-users. Cannabis users will be asked to quit using cannabis for 11 weeks and will be required to attend 25 visits during the 11 week abstinence/contingency management period. Non-users will be asked to return to the clinic once a week for 11 weeks. Abstinence will be determined by self-report, qualitative urine rapid screening test at the clinic and quantitatively via EIA analysis of THC (cannabinoids) and, by LCMSMS analysis of 11-nor-9-carboxy-∆ 9-tetrahydrocannabinol (THCCOOH) performed by an analytical lab contracted by the study team. Semen sample for both groups will be collected prior to the start of abstinence and after 11 weeks. Semen analysis and DNA methylation of sperm cells will be compared.
