The samples were checked for semen volume, total sperm count, sperm concentration, and sperm motility (how well the sperm can move and swim, which affects fertility). Overall, the researchers found no significant difference in these measurements when comparing cannabis users with people who don't use cannabis.

Use of cannabis at both therapeutic and recreational dosages also showed a reduction in sperm motility, the ability for sperm to move efficiently, as well as viability, how long the sperm live. In addition to the changes in sperm quality, counts, and viability, marijuana also impacts the reproductive hormones, such as the luteinizing hormone (LH).

Both animal and in vitro studies reported a negative impact of cannabis (THC/cannabinoids) on male fertility with a reduction in sperm count and motility and with altered morphology (Murphy et al., 2018; Innocenzi et al., 2019; Whan et al., 2006; Verhaeghe et al., 2020).
Sperm Count — Cannabis use is strongly associated with reductions in sperm count and concentration in animal and human studies. In 20 chronic marijuana users who smoked marijuana at least 4 days per week, those who smoked 10 or more times per week had a significantly lower sperm count than men who smoked 5 to 9 marijuana cigarettes per week.
