What is a penis and how do you determine its size?

The penis is an important male reproductive organ. You will often hear biology teachers talk about it when explaining the human body. So what exactly is the penis? Many women are curious about this. In fact, the penis is the reproductive organ of male animals, and its main functions are urination and ejaculation. Let’s take a closer look at it below!

The penis is the mating organ of male animals. It is usually soft and hidden in the foreskin. It becomes erect, elongated, thicker and harder during mating, and ejaculates semen after penetration into the female's vagina. The main functions are to excrete urine, semen and to mate.

Some young men are very curious and always secretly compare the size of their penis with those around them in places like bathhouses. Once they find that their penis is shorter than others, they feel traumatized and afraid of being ridiculed by others. They feel ashamed, inferior and depressed and may even never want to enter public bathhouses again. In fact, most of them have normal penises.

So what kind of penis is considered small? Let’s first take a look at how big a normal penis is. The average length of the penis in a flaccid state is 5-6 cm, and the average length when erect is about 11-13 cm. Because the penis changes greatly when it is in a flaccid state, such as being relatively shorter when you are nervous, tired, or cold, and its size remains relatively constant after full erection, the best time to measure is when the penis is fully erect. Pinch the coronal sulcus of the glans penis with your thumb and index finger, press the pubic symphysis at the base of the penis with the tip of a ruler, and measure the length from the glans penis (external urethral opening) to the base. The result is the length of the penis.

When judging whether the penis is short, you should be careful to eliminate individual differences and not mistake a normal person with a small penis as having short penis. If a normal penis is small but does not affect sexual life and is not accompanied by sexual degeneration, it should not be treated as a disease and does not require diagnosis and treatment. The sexual harmony between men and women mainly depends on a sound sexual psychology, good nerve reflexes, a normal endocrine system, perfect blood circulation and sufficient sexual knowledge, and has nothing to do with the size of the penis. Generally speaking, adult males can better meet the requirements of sexual life when their penis reaches normal length after erection. It is not necessary for the erect penis length to reach a higher standard in mind. The size of a man's penis is not the key to improving the quality of his sex life.

Micropenis, as defined medically, is a congenital abnormality. The average length of a normal male newborn's penis is 35 to 7 cm, while micropenis is usually less than 1 cm. During puberty, the male micropenis becomes child-like, with a flaccid length of less than 4 cm and a full erection length of less than 7.5 cm. There is no scrotal development, poorly developed or absent testicles, a small prostate, no erectile function, and poorly developed secondary sexual characteristics (such as vocal cords, beard, pubic hair, Adam's apple, etc.). There are no sperm and no fertility. The cause of the disease is a childish disease or hypogonadism, or sexual deformity or hypopituitarism and pineal insufficiency. For people with small penis, they should be injected with a certain dose of androgen under the guidance of a doctor before entering puberty. This can promote penis development, prompt the appearance of male secondary sexual characteristics, and help them have a normal sex life after marriage. Otherwise, if the medication is used after adulthood, it will be difficult to have a good effect.

A large penis is medically called a "giant penis". As the name suggests, it means that the penis is abnormally large. The causes of giant penis include: premature puberty, congenital dementia, dwarfism, hyperpituitarism, adrenal dysfunction, etc. It can be treated by treating the underlying disease and adjusting endocrine hormone levels.
