They drink drugs to health 284 the anterior point of their connection is a sensitive and capable (unlike the others) to an erection organ, which has the size and shape of a small pea. It is a clitoris, an organ homologous to the male penis that is, developing from the same embryonic rudiment as the penis (if you swap them, you can reach a consensus). Like the penis, the clitoris contains a cavernous tissue which is filled with blood during sexual excitement. Behind the clitoris is the opening of the urethra, which is used only for urination, and a much wider opening of the vagina. Until the first sexual intercourse this opening is usually closed (not completely) with a thin membrane – hymen. Note that Biology considers a man and a woman as independent objects, with characteristic chemical reactions and a mechanical feature of the sexual process – like a robot. Fertilization AFTER A SHORT WARMING-UP , stumbling upon the vagina the penis ejects at least 3-5 ml (about 300 million spermatozoa) of the sperm. This army begins to actively search for the egg cell, diving into various acidic medium and bumping onto corners. Spermatozoa (all together) move up the vagina and penetrate the uterus, partly due to their own energy, and partly due to the muscle contraction of these organs. Most spermatozoa die on their way, but some get to the fallopian tubes and move along them further. Spermatozoa have the ability (effected by prolonged training) to move against the current, and probably that the very current that directs the egg cell from the abdominal cavity to the fallopian tube (to be eaten) helps them to go the right way. Thus, the first major obstacle is a stormy current with waterfalls. Fertilization usually occurs in the upper third of the fallopian tube (spermatozoa need to have a roulette with inch markings), by the time the egg reaches the bottom of the tube, it loses its ability to be fertilized ( in other words, hardens on the way). Out of the millions of spermatozoa, only one fertilizes an egg cell. Each Homo Tsapus egg is surrounded by a layer of cells (originating from the egg follicle), the so-called corona radiata , through which the sperm has to pass before it joins the egg cell. Many spermatozoa get stuck in this gauge ring, but some manage to bypass it. Individual cells of this layer are linked together by hyaluronic acid – a complex organic substance, on which the enzyme hyaluronidase acts. Since each sperm contains very little hyaluronidase (it is usually supplied with neutralizers of nitric and sulfuric acid) , only the joint action of several hundred thousand spermatozoa can lead to splitting the hyaluronic
