Discipline your sexuality for it has the proclivity to cause a productivity that can influence now and posterity. It’s completely the invention of clothes, not nature that made “private parts” private. Yes, I’m talking about one of the most private parts of male reproductive system namely –THE PENIS!
The penis — if you think about it — is the most enterprising engineering feat imaginable — a cantilevered structure, hydraulics, propulsion, pistons, compression, inflation, heat sensitive — practically every engineering characteristic — towers, draw-bridges, rocket-ships — no man-made engineering structure to match it. Jokes Apart , without further delay ,let’s get started to know about some of the most important aspects about PENIS.
The structures of the male reproductive system include the testes, the epididymides, the PENIS, and the ducts and glands that produce and carry semen. Sperm exit the scrotum through the ductus deferens, which is bundled in the spermatic cord. The seminal vesicles and prostate gland add fluids to the sperm to create semen.
The penis is the male organ of copulation (sexual intercourse). It is flaccid for non-sexual actions, such as urination, and turgid and rod-like with sexual arousal. When erect, the stiffness of the organ allows it to penetrate into the vagina and deposit semen into the female reproductive tract.
The shaft of the penis surrounds the urethra. The shaft is composed of three column-like chambers of erectile tissue that span the length of the shaft. Each of the two larger lateral chambers is called a corpus cavernosum (plural = corpora cavernosa). Together, these make up the bulk of the penis.
Ejaculation: The corpus spongiosum, which can be felt as a raised ridge on the erect penis, is a smaller chamber that surrounds the spongy, or penile, urethra. The end of the penis, called the glans penis, has a high concentration of nerve endings, resulting in very sensitive skin that influences the likelihood of ejaculation. The skin from the shaft extends down over the glans and forms a collar called the prepuce (or foreskin). The foreskin also contains a dense concentration of nerve endings, and both lubricate and protect the sensitive skin of the glans penis. A surgical procedure called circumcision, often performed for religious or social reasons, removes the prepuce, typically within days of birth.
Erection: Both sexual arousal and REM sleep (during which dreaming occurs) can induce an erection. Penile erections are the result of vasocongestion, or engorgement of the tissues because of more arterial blood flowing into the penis than is leaving in the veins. During sexual arousal, nitric oxide (NO) is released from nerve endings near blood vessels within the corpora cavernosa and spongiosum. Release of NO activates a signaling pathway that results in relaxation of the smooth muscles that surround the penile arteries, causing them to dilate.
Blood flow, Erection and Increased size of Penis: This dilation increases the amount of blood that can enter the penis and induces the endothelial cells in the penile arterial walls to also secrete nitric oxide and perpetuate the vasodilation. The rapid increase in blood volume fills the erectile chambers, and the increased pressure of the filled chambers compresses the thin-walled penile venules, preventing venous drainage of the penis. The result of this increased blood flow to the penis and reduced blood return from the penis is erection. Depending on the flaccid dimensions of a penis, it can increase in size slightly or greatly during erection, with the average length of an erect penis measuring approximately 15 cm.
Last but not the least, knowing thyself is an integral part of absorbing Sex Education. It demands to know about the reproductive system and organs, their function, hormonal balances and imbalances, physical and mental changes and the list goes on. Know about your organs and spread the knowledge. Wishing everyone a very safe and sound mental health condition!
