The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
the reality is that dopamine is released on anticipation and consummation of sex and reproduction. And after orgasm, regardless of chromosomal background there's a dramatic decrease in dopamine and an increase in a hormone called prolactin.

And what's interesting about this is that after copulation prolactin goes through the roof and prevents further copulation dopamine crashes
Now, prolactin is associated with milk let-down in lactating mothers. It's also present in males and in general prolactin creates a sense of lethargy of stillness and lack of desire to move and lack of desire to pursue more of whatever released the dopamine. Prolactin in fact, sets the refractory period on a male's ability to mate again
in both men and women, sex increases prolactin post-sex, it's just the way that the system works, it's that testosterone and dopamine increase in the seeking-out and the behavior of sex, and then after sex, prolactin levels go up, there's kind of a quiescence, the whole nervous system is promoted towards calm, and this may actually have something to do with pair-bonding and the encouragement of individuals to spend more time together to exchange different smells and hormones, and maybe even pheromones, and we're going to talk about pheromones in a moment.
And just so you'll never forget it, males' elevated levels of prolactin are actually what set the refractory period after ejaculation and prevent erection for some period of time.
and that prolactin is associated with the refractory period during which erection can't occur, another, perhaps, orgasm can't occur in females, et cetera.
one of the uh implications for refractory time is Prolactin so when you have an ejaculate your orgasm your prolactin levels go up and that's been implicated as the reason for the refractory time
one of the implications for refractory time is Prolactin so when you have an ejaculate your orgasm your prolactin levels go up okay and that's been implicated as the reason for the refractory time
