Question

what hormones are released during male ejaculation

Answer 1

Then there is the biochemistry of the orgasm itself. Research shows that during ejaculation, men release a cocktail of brain chemicals, includingnorepinephrine, serotonin, oxytocin,vasopressin, nitric oxide (NO), and the hormone prolact.

Answer 2

Oxytocin and vasopressin, two other chemicals released during orgasm, are also associated with sleep. Their release frequently accompanies that ofmelatonin, the primary hormone that regulates our body clocks. Oxytocin is also thought to reduce stress levels, which again could lead to relaxation and sleepiness.
