Men falling asleep after sex is not just a cliche. Research is starting to show that instead of men simply not wanting to spend time snuggling with their partners after sexual intercourse, there may be a medical reason for a man's urge to fall asleep.

Why Do Men Feel Tired After Sex?

Research is showing that men release different chemicals and hormones after ejaculation that promotes sleep and reduces the chance of them engaging in sexual activities again for a while. What researches found was that after a man experiences an orgasm, his body naturally releases the following,

1. Prolactin: This hormone is released during an orgasm, and is responsible for promoting fatigue and drowsiness in men. To fight off the effects of the hormone, some men have found that the mood enhancing chemical dopamine can revive their energy levels.

2. Oxytocin: This hormone not only helps to reduce minor aches and pains, it is also released during an ejaculation and can cause drowsiness. The hormone is also responsible for the feeling of satisfaction many men feel during a sexual release.

3. Vasopressin: Released by the brain after an orgasm, it is responsible for constricting the blood vessels and restricting blood flow to the penis. This makes it difficult to achieve another erection.

4. Neurotransmitters: This include serotonin, nitric oxide, and norepinephrine which make up the main neurotransmitters that are responsible for relaxing the body after intercourse. Once the muscles are completely relaxed, sleep usually follows.

While not a hormone or chemical, exercise can also cause men to feel sleepy after sexual intercourse. Even if men are not in control during the sexual activity, they can still feel the effects of the exercise. One theory is that since men have a larger muscle mass than women, they will generally exert more energy during sex and when experiencing an orgasm.

Other Reasons Men are tired after Sex

Women are not the only ones whose hormonal levels can change during their monthly cycles, men can also experience a rise and fall in their testosterone levels. When the levels of testosterone fall, not only can his libido be affected but also his energy. Men who are able to keep track of the times during the month when their testosterone levels are low, tend to have a more fulfilling sexual life.

The Penis Can Be Used to Judge Overall Health

While low levels in testosterone can cause a decrease in a man's libido, it can also signify a more serious health complication. Some physicians loosely use a man's penis to judge his health. An inability to achieve an erection may not only be due to being tired, but could be a sign of a restricted blood flow. Some of the causes can include, heart and kidney disease, diabetes, and endocrine disorders. Fatigue, poor diet, and even relationship issues can also cause problems with restricted penile blood flow.

Other causes for an erectile dysfunction can also include excessive cycling which can cause problems with numbness in the genital area, along with skin irritations and problems sustaining an erection. Using a well-padded seat that can be adjusted to relieve pressure on the groin area, can help to reduce the risk of developing erectile problems.

Sleep apnea or OSA can not only be a serious health complication, it can also affect a man's ability to perform in the bedroom. The problem effects rapid eye movement which is not only necessary for a good night's sleep, but it is also necessary for sexual well-being. Simply treating you sleep apnea, can cause a noticeable difference in your ability to maintain an erection.

Another problem for men and their ability to have a satisfying sex life, is that as they age their sperm counts continue to decrease. While infertility may not be a problem for some older men, it can adversely affect their sex lives. Another common cause for a man's low sperm count is varicocele, which occurs when the veins in the scrotum become enlarged.

While these conditions may not necessarily cause men to fall asleep after sexual intercourse, they can interfere with his ability to perform in the bedroom. Many men have learned that once they have treated their sexual disorder, falling asleep shortly after having an orgasm is no longer a problem in the relationship.

Conclusion
Men fall asleep after having sex due to the different hormones and chemicals that are released in the body after having an orgasm, and that is not likely to change. To make it less of a problem in their relationship, treating an existing sexual dysfunction can help. Not only will both partners be satisfied, there is a chance that they both might want to fall asleep after having sex.
