The penis is also called "yang organ", which refers to the male reproductive organ. Unlike women, men's penis has been exposed since embryonic development. It also has a special "magical" feature. When stimulated by external factors, it will "erect", from small to large, from thin to thick. So, are all men's penises the same?

Same function, different shapes and sizes

In terms of function, they are the same, but in terms of shape, there are differences in size and length, which directly leads to different quality of sexual life. The normal adult penis is 7-9 cm in the flaccid state and about 11-16 cm when erect. If it is less than 5 cm in the flaccid state and less than 10 cm when erect, it is called a short penis.

Key Features

The penis is the primary organ of sexual activity, and its main functions are urination, sexual intercourse, and ejaculation.

sexual intercourse

Sexual intercourse broadly refers to the mating behavior between male and female animals of different species, which requires the participation, stimulation and excitement of reproductive organs. From a biological perspective, the purpose of sexual intercourse is reproduction.

Sexual intercourse refers to the act of a man inserting his penis into the vagina and ejaculating due to arousal to transport sperm. During sexual intercourse, the man's penis becomes erect, and the woman's vagina becomes lubricated due to arousal, making it easier for the penis to enter the vagina.

urination

Micturition: Urine is produced by the kidneys and then temporarily stored in the bladder through the ureters. When a certain amount of urine is stored, it is excreted from the body through the urethra multiple times. Micturition is a complex reflex activity controlled by the central nervous system. The penis is the outlet for urination in male animals.

Ejaculation

Ejaculation is the reflex action of male animals to eject semen during sexual intercourse. Human ejaculation is a series of coordinated actions of various parts of the reproductive system, and semen is ejected from the penis. It includes a two-step spinal reflex, the primary center is in the lumbar spinal cord, and its sensory impulse is transmitted by the touch receptors of the glans penis.

Ejaculation is a complex process that includes erection, ejaculation, ejaculation and orgasm. Erection is due to the swelling and hardening of the penis, and its primary nerve innervation comes from the sacral nerve plexus and the pelvic visceral nerves or erectile nerves. Ejaculation involves collecting semen before ejaculation and transporting it to the prostatic part of the urethra. With the closure of the bladder neck and the distal urethral sphincter, the prostatic part of the urethra becomes a reservoir of semen. This will induce ejaculation, that is, the rhythmic ejection of semen through the urethra, and the participation of the skeletal muscles of the perineum is essential in this process.
