Unfortunately these studies have only been done on older men...
This is the one the article references:
Low PRL is related to several metabolic, psychological, and sexual unhealthy characteristics in European men. Checking PRL might be useful to stratify men for cardiovascular risk and to encourage appropriate lifestyle changes.

Here's another suggesting ed and metabolic issues:
Our findings demonstrate that, in subjects consulting for sexual dysfunction, PRL in the lowest quartile levels are associated with MetS and arteriogenic ED, as well as with PE and anxiety symptoms. Further studies are advisable in order to confirm our preliminary results in different populations.

both of those studies just looked at prolactin and how low prolactin was associated with ED, which has no relevance to anyone using hormones
it’s hard to explain but I’ll try to give and example
low testosterone levels in hypogonadal men was associated with a bunch of Heath issues ,diabeties, High cholesterol, obesity, etc so one could assume it is actually testosterone that is the cause
However low testosterone also means low estrogen
So they did an actual study on men and animals and Suppressed natural hormones while adding either estrogen or testosterone with an aromatase inhibitor.
That way they could actually see what was the CAUSE, which is where causation comes from. The cause was actually declining estrogen in many of the issues related to hypogonadal men.
This is why you always hear correlation, doesn’t mean causation.
It is like if the power went out on a Sunday, so you blamed the power outage on people going to church since people also go to church on Sunday.
well maybe it could have been because of people going to church but chances are there’s an actual reason that caused it
so the studies showing people with elevated prolactin getting better from taking a medication that supresses prolactin is valid since it is a direct causation of lowering prolactin
