When we are in high school, even in the early years of science classes, we learn how the mechanism of human reproduction works. Then in high school, biology lessons deepen the study and teach us a little more about the incredible mechanism that generates lives.
In the personal area, slowly we discover several news that, as much as friends comment, only become really natural after being tried. Sex and its mysteries: When we think we know everything, science comes and presents us with something new.
Get to know ten of the most interesting curiosities about the subject, things that you (almost certainly) have no idea that work like this.
1 ? Size is document? Sexologists generally claim that penis size has nothing to do with sexual performance, so men with large penises may or may not be reassured. But did you know that the testicles may also have different sizes? Research shows that European men have testicles twice as large as those of the Chinese.
2 ? Sperm are extremely fast when in the female body. In general, on the way from the penis exit to the fallopian tubes, they take only five minutes. All this speed seems strange compared to how long it can take to fertilize an egg: up to five days.
3 ? Female orgasm continues to be the object of study. Not all women can reach it and science tries to explain the reasons. What is known so far is that a woman has to go through three stages to get to it: desire or libido, arousal, and finally lubrication of the vagina.
4 ? Women face a real physical marathon during sex. The vagina is lubricated and expanded, while the clitoris and breasts swell and the heart speeds up, as does blood pressure and breathing. In addition, the muscles of the thighs, buttocks and hands are tensioned.
5 ? Can female arousal be too short? or too long. Apparently it starts 10 to 30 seconds after the erotic stimulation begins. Thereafter, it may only last a few minutes or even whole hours.
6 ? While sperm is the smallest cell in the human body, the egg is considered the largest of them. It measures approximately 0.14 centimeters and in some cases may even be visible to the naked eye.
7 ? Men and women are completely different when it comes to orgasm. Men can reach it with just three to five minutes of stimulation. Already the woman needs a period of about 15 minutes for this.
8 ? It is scientifically proven that sex has numerous benefits to human health. Besides helping to relieve stress, it burns calories and favors the feeling of well-being. Studies further demonstrate that it can improve sleep quality due to hormones and the numerous substances released by the brain during sexual activity.
9 ? Many women have unplanned pregnancies, but after a couple talks and decides to have a baby, on average they will achieve a pregnancy after five months of trying.
10 ? When we study the so-called "asexual" living beings, we do not imagine that this feature may present itself in the human species. According to surveys, approximately 10% of the world's population is not attracted to either men or women.
