Isolating prolactin increase only to masturbation is silly and misleading. It most likely stemmed from self-righteousness religious people with their hyper-moralistic judgments of a "natural" behavior. Prolactin is increased after orgasm [PERIOD]
Prolactin counters catecholemines of the pre-sexual release i.e. in the excited state and is proportional to the sense of excitement and satisfaction achieved. It's perfectly normal and that is within context. If you fear this natural response as if it's the boogeyman, then simple solution: don't have sex or masturbate.
I still look for people who masturbate or have sex to measure their prolactin after 24hour or 48hours.
In my case it was very low when tested. I will keep testing along the years anyway.
However "prolactin stays high for a long period after orgasm" spreads a bit too much like a gospel without personal testing it's literally not helping anyone in the community.
Unfortunately many people on the forum fight against Prolactin without even knowing their levels in any condition they are (after orgasm or month of doing nothing).
So many of the hormonal theories were not true on me at all, like the claim that high estradiol means high prolactin automatically, with two occasions I had very high estradiol and very low prolactin for example.
