and it turns out, there are two studies that I could find that were quality studies on PubMed that address this, that sex and ejaculation itself does not reduce testosterone levels although it will increase prolactin levels for the reasons I described a moment ago, however, abstinence or sex without ejaculation for a week or more will increase testosterone levels up to 400%, so the answer is actually complicated, it's not straightforward, what it means is that sex itself increases testosterone, however, abstinence also increases testosterone even further, so it's a nuanced answer, and I hope this is satisfactory, no pun intended, to those of you that have been asking me, what is the relationship between sex and ejaculation and testosterone and dopamine?
