Experts are raising concerns about the potential negative impact of both recreational and medical cannabis on male fertility. Studies indicate that chronic and heavy cannabis use can affect reproductive health, with potential links to decreased sperm counts, reduced sperm mobility, and hormonal disruptions.
While human evidence remains mixed, a Harvard-linked study noted twice as many miscarriages among women using cannabis during fertility treatment compared to non-users. Male infertility is a significant factor, contributing to approximately 45% of infertility cases worldwide.
Cannabis compounds, THC and CBD, mimic the body's natural endocannabinoids, potentially interfering with the endocannabinoid system that regulates fertility. This interaction may impair sperm quality and disrupt hormone levels like FSH and LH, which are crucial for sperm production.
Medical professionals recommend men planning to conceive stop cannabis use at least three months prior to conception. Experts state that the negative effects on fertility may be reversible once cannabis use ceases, allowing the body to produce healthier sperm. The American Society for Reproductive Medicine also advises avoiding recreational drugs during conception attempts.
