Dr Neil Stanley said although it is frustrating for women when their male partners doze off, science could provide the answer The study also showed that the brain switched off almost all sexual desire after orgasm. The famed Masters and Johnson tried to replicate the first insuck experiment and failed. Told to bugger off, experiment over. This has been observed in horses and pigs before: Basically, orgasm causes pressure changes between the uterus and vagina, sucking the sperm inwards and increasing the chances of fertilization.
You would be amazed to know that there are also cases where doctors are suggesting people suffering from insomnia to masturbate before going to bed. While I haven't been able to find any science-backed evidence that post-sex sleepiness definitively affects men more than women, there are a few hypotheses floating around as to why it seems that way. Some of them, like prolactin, oxytocin and vasopressin, have been linked to sleep as well as sex. The best examples of foods and beverages to increase dopamine are chocolate and coffee.

Number one, the sexual activity to be engaged in was masturbation. He did his doctoral thesis on gall wasps and researched and published papers about them at the American Museum of Natural History in New York. Because men usually have more muscle mass, they get more tired. Cecil Adams Send questions to Cecil via. Arousal is dominated by their brains, rather than physical contact. Now, insuck is not without its skeptics. Studies have also found that those with spinal cord injuries resulting in a lack of connection between the brain and genitals, can still sleep-orgasm.
A sudden loss also brings restlessness which could also trigger sleep. Eating chocolate increases dopamine and serotonin. Yeah, that's the kind of scientifically-validated research that'll confirm your hypothesis, for sure. There are even more great benefits of oxytocin such as lowering and even improving — which often goes to the wayside during times of stress. This phenomenon is really due to many complex physiological processes that are beyond his control.
It's best to simply give in to feelings of drowsiness after sex. These aren't really the sorts of things you want to do during vigorous exercise, as they lead to oxygen deprivation and—all together now—sleepiness.
