Recovery time -- the time it takes to rebuild an erection after

interruption or ejaculation -- depends on the individual and it also

varies with age.



Why is it that some guys have shorter recovery times? Why are they

ready to give it another go quicker?



The answer is in a little understood brain chemical called prolactin. Men

who are deficient in prolactin have quicker recovery times.



[Update:



In other words, low prolaction means more erections and quicker

recovery.



Low levels of prolactin have also been linked with stimulate sexual

appetite. In 2006, researchers from the Seoul National University

College of Medicine in Korea studies 261 married men to try to

understand the link between prolactin levels and sexual desire. They

discovered that 62.5% of these married men were not sexually active

at all. Digging into the data, they learned that the prolactin levels of the

men who were having sex averaged 4.8 , while the prolactin levels of

the men who were not sexually active at all averaged 6.8. In other

words, the men who were shut down sexually had prolactin levels that

were about 42% higher than the sexually active men. ]



Scientists have found that, when you ejaculate, you release a mix of

brain chemicals --- norepinephrine, serotonin, oxytocin, vasopressin,

nitric oxide (NO), and the hormone prolactin.



Prolactin gives you the feeling of sexual satisfaction. It also sets your

timer for recovery before you can have sex again.



Prolactin levels increase when you sleep. Prolactin's release during sex

is probably the reason men doze off right away after sex.



Ever wonder why you're sleepier after sex than you are after

masturbation? Prolactin is the reason. It turns out that less prolactin is

released after masturbation than after intercourse. No one knows why.



So is there any way to reduce your prolactin levels? The science is still

being conducted in this area. What is known from several studies on

mice is that lowering calorie intake also seems to reduce the amount of

prolactin in your blood.
