I would be interested to know if the various modes of MJ intake (vaporizer vs joint vs edibles) has an impact. In theory, vaporizer should have less "bad" chemicals, but there is no data to base this off of.
This is an important point. However, the question only asked about smoking marijuana thus other forms of use are uncertain.
Wondering if the National Survey of Family Growth obtained data regarding sperm counts. This would be helpful to cast light on the association between sperm counts and marijuana use. Other studies have suggest a negative interaction however in the context of this data, it could be tempting to speculate that such a relationship may not be identified (https://academic.oup.com/aje/article/182/6/473/82600).
Unfortunately, NSFG does not have data regarding sperm counts.
Great point. Unfortunately, NSFG does not have that data. While this study is not consistent with some other reports of marijuana and semen quality, there is now other TTP data that shows similar findings.
