Scientists also reported that melatonin was also found in semen, which restores a person's biological rhythm and strengthens sleep.

Semen does not make you fat

Semen has a high protein content and contains useful minerals and vitamins such as magnesium, potassium, sodium, vitamin B12 and vitamin C, for example. The caloric value of an average ejaculation, during which up to 6 milliliters of semen is released, is only 15-30 kcal. Prof. Ingrid Fleischer from Hamburg (Germany) assures that a woman who often gives blowjobs and swallows her partner's semen will be able to lose weight much faster than others, because semen contains alkaline substances that help burn fat.

Semen boosts mental performance

In the laboratory of reproduction at the National Medical Center in Oslo under the direction of Professor Sven Norberg for a year as experiments are going on. Every week, 15 female volunteers swallow freshly tested semen, which their husbands or lovers hand over in a neighboring office. The semen is exactly 5 milliliters (the standard rate of male ejection at orgasm). It would be possible to do the same with a blowjob at home, but for the purity of the experiment, the entry of ejaculate into the body must be strictly fixed. And this is impossible at home. In the laboratory, the changes in the metabolic system are also confirmed by appropriate analyses.

Prof. Sven Norberg explained that the male protein has miraculous properties. Semen contains the hormone prostaglandins, which stimulate the production of estrogen hormones in women. This means that metabolism improves, skin diseases go away, and breasts get bigger. In addition, when swallowing sperm, a woman gets a certain dose of DNA of the partner, and in a future pregnancy it will help the fetus to take root in the uterus. But that's not all.

Two years ago in Oslo there was a beauty contest for female nursing students. The girls had to have not only perfect looks, but also show that they were smart. The tests amazed the jury: only 5 young ladies out of 300 coped with rather difficult tasks on logical thinking. And they were the ones with the highest IQ. Not only the founders of the contest, but also scientists paid attention to the smart girls. When collecting information, it turned out that these girls began to live early sexual life. Moreover, in the questionnaire they all wrote that they love oral caresses and always swallow their partner's sperm.

– We scanned the brains of women with high IQ and found: the blood-brain barrier (a kind of "filter" between the blood and the nervous system) in them is not as permeable than in less advanced peers – the researchers explain – the blood-brain barrier protects the brain from toxins, germs and excess cholesterol. This means that smart women are not at risk of developing Alzheimer's disease, senile dementia or stroke in the future. But most importantly: thanks to male sperm there is a sharp increase in the activity of brain cells – astrocytes. Such a stimulating effect on brain cells have special hormones and enzymes that are included in semen. So much for an above-average IQ!

So, are you impressed?! You bet! And now, after all of the above, with a clear conscience we move on to the eternal, the most common and ambiguous question for both men and women....

Of course, to swallow or not to swallow semen, if oral sex led to orgasm of the partner – a personal matter of each girl. Forcing her to forcefully do it, against her will means jeopardizing the future of further relationships. Therefore, you need to agree on this in advance with the guy or orient yourself on your sensations.
