The male reproductive organ is the male reproductive system, which is the human organ for male reproduction and procreation. It consists of two parts: the internal and reproductive organs. The reproductive organ includes the scrotum and male genitals; the internal genitals include the prostate gland (male testicles), ejaculatory ducts (episodic cysts, ejaculatory ducts, vas deferens and urethral opening) and their attached glands, seminal vesicles, male prostate and bulbourethral glands. The male reproductive organ begins to grow and develop during puberty, and after growth and development are complete, it has the function of reproduction.

Male testicles are organs that produce sperm and metabolize male hormones, so they are also called sex hormones. Male hormones maintain the secondary sexual characteristics of men, namely, the protrusion of the Adam's apple, the growth of beards, and more muscular development, and maintain male sexual function. Growth hormones act on the whole body through the blood circulation system.

The epididymal cyst is located on the posterior sides of the male testicle and is flat.

The sperm produced by the testicles is transferred to the epididymal cyst for storage and continues to grow and develop in the epididymal cyst. The seminal vesicle and prostate are the attached glands of the male reproductive organs, which metabolize a kind of alkaline fluid, which is milky white and can assist the activity of sperm. It is the key component of semen.

Ejaculation process

The key role is to produce male sperm and metabolize androgen (testosterone). The fusion of male sperm and egg cells for fertilization is the key material condition for the reproduction of offspring; testosterone is the key substance for maintaining male secondary sexual characteristics (secondary sexual characteristics).

One end of the ejaculatory duct is connected to the epididymal cyst, and the other end opens at the urethral opening. There is one on each side. When a man ejaculates at the climax of sexual excitement or ejaculates frequently, the semen is discharged from the body through the ejaculatory duct and urethral opening. Each discharge of semen is generally 2-3 ml, and 1 ml contains about 100 million live sperm.
