Fellatio is an activity enjoyed by both humans and animals. However, its ending can be a bit problematic. Those who do, very quickly wonder whether to swallow the seed or spit it out, so read up on what the scientists have to say before making a decision.
Is it Better to Swallow?
Fans of swallowing might like the fact that a study was published in 2002 that found that hormones in semen can have a positive effect on a person’s mental health. However, it should be noted that in this study sperm entered the participants’ bodies vaginally, not orally, and it was not possible to establish a causal relationship between sperm and emotional state. Nevertheless, the results are still intriguing.
According to the authors, women who do not use condoms during intercourse have lower levels of depression than those whose partners use condoms, and “women’s depressive symptoms and suicide attempts were proportional to the consistency of condom use.”
Much more research would be needed to confirm such an effect, but the researchers note that semen contains significant amounts of mood-enhancing hormones such as oxytocin and serotonin, which were found in women’s blood when the sperm entered their bodies.
It’s hard to say if the same thing happens after swallowing sperm. But it can also be done for other reasons, as 100 ml of male ejaculate contains about 5000 mg of protein, as well as quite a large dose of zinc and small amounts of vitamin C, magnesium and potassium. Of course, daily doses of these substances are better obtained through food.
In addition to the good vitamins, semen also contains an antioxidant called spermidine. Studies show that it slows the aging process in yeast, worm, fly and mouse liver cells. This effect is due to spermidine’s ability to regulate the self-digesting process of cells called autophagy. However, it seems unlikely that such an effect would be achieved with oral sex.
Is It Better to Spit It Out?
On the other hand, by spitting and not getting all of the above, you greatly reduce your chances of contracting sexually transmitted diseases such as HIV, herpes, and hepatitis. Of course, these diseases can also be contracted by not swallowing semen, and the chance of getting an infection increases significantly if the person performing oral sex has open sores in or near the mouth.
Spitting is also necessary for those who are allergic to sperm – this is called Human Seminal Plasma Hypersensitivity (HSP). This allergy, caused by certain proteins produced by the prostate, can cause a range of local and systemic symptoms. This is why some people cannot enjoy sex without protection.
Fortunately, this condition is very rare and will not cause concern for most oral sex users.
There are pros and cons to your decision to spit out or swallow, but when it comes to climaxing, it’s best to stick with your personal preference alone.
