Reproduction


Did you know that all of us were once a single cell? Looking at your body is hard to believe now, but we have all been a zygote, an egg cell.

Talking about sex

In other times, sex was often a forbidden subject. At home, no one spoke "of these things." Among boys, information was usually passed on by older friends in hidden conversations. And because they didn't always know what they were talking about, many subjects were left unclear. With girls, it was something like that too. Shame and even fear often prevented manifestations of their doubts and emotions.

But times have changed. It can still be a little difficult for parents and other adults to talk about sex. This depends in part on the education they have received - and young people need to understand this limitation. Here, we will talk very naturally about sex, a subject that often arouses so much curiosity in the teenage years.

What is sex for?

This question has many answers. The most commonly used answer is: sex is to ensure the perpetuation of species.

In fact, in living beings in general, the function of sexual activity is to give birth to new beings and thus maintain the continuity of the species. In most animals, the male only crosses with the female when she is fertile, when her body is at the right time to breed puppies.

And in the human being?

For humans, reproduction is usually just one of the functions of sexual activity. Sexual intercourse is also a way to obtain pleasure and joy, to give and receive affection and affection. It is one of the most intimate expressions that can exist in the relationship between two people, as it involves deep emotions. No wonder sexual intercourse is also called "making love."

To better understand certain aspects associated with reproductive function in humans, we need to understand the relationship between female and male genitals for this to occur.

The sexual act and the beginning of a new life

In sexual intercourse, the attraction of stimuli and hormonal reactions makes touching and tactile sensations very pleasurable. The loving games, the caresses, the tenderness, the contact of lips and other parts of the body, the excitement, all make up the ritual of preparation for the sexual act, which is the apex of the encounter between the sexual partners.

With arousal, the man's penis swells and becomes hard, erect, and the woman's vagina releases a lubricating secretion. All of this facilitates the penetration of the penis into the vagina when intercourse or intercourse occurs, which usually causes a very pleasurable sensation in both partners.

In the complete vaginal sexual act, the man ejaculates, that is, a liquid comes out of the penis and is deposited in the vagina (when there is no condom use). This fluid, semen or sperm, contains sperm originating from the testicles. Of the millions of sperm that have been deposited in the vagina, only hundreds reach the egg, and only one sperm can enter it. This is the opportunity for a new life to arise, for conception to occur.
