Humans use sex to reproduce. In humans, the male reproductive organs start functioning at a certain age, this is called puberty. Complex multicellular organisms such as humans have specialized reproductive organs to produce sperm and eggs, bring sperm and eggs together for fertilization, and develop the zygote into an infant.
The testicle is an egg-shaped organ that lies outside the abdominal cavity of the male. There are two testicles in men. The testicle is the primary reproductive organ of a man or men. The function of the testicles is to produce male sex cells or gametes called sperm. Besides, its function is also to produce male sex hormone – testosterone. Their number is two. The testis is the primary reproductive organ found in males. The testicles are located in a sac-like structure made of skin which hangs outside the body. This is called scrotal sae. Male gametes i.e., sperms are produced by the cells of the testis. The temperature required for sperm production is less than body temperature. This is why the testicles are located in the scrotum outside the abdominal cavity. An average ejaculation contains about one teaspoon of semen.
Some important Male Reproductive organs
The human male reproductive organs consists of the following organs –
Testicles
Epididymis
Spermatic duct
Seminal vesicle
Prostate gland
Penis.
Gonads in Male Reproductive organs
These are small organs that produce either Langley cells or gametes (Sex cells and Gametes). Besides, they also secrete some hormones. These organs are called gonads. In males, the gonads are called testis and are responsible for producing male reproductive cells – sperm. It is present in the scrotum outside the abdominal cavity. There are two parts of the testicle. The first one produces sperm and the second one secretes testosterone hormone as an endocrine gland.
Testicles and Scrotum in Male Reproductive organs
Testicles are the main and other accessory organs among the human reproductive organs. Sperms are produced in it and the male hormone testosterone is secreted from it. The testis is the primary reproductive organ found in males. These are male gonads which are oval. Their number is two. The testicles are located in a sac-like structure made of skin which hangs outside the body. This is called Scrotal Sae. Male gametes i.e., sperms are produced by the cells of the testis.
The temperature required for sperm production is less than body temperature. This is why the testicles are located in the scrotum outside the abdominal cavity. An average ejaculation contains about one teaspoon of semen. The number of sperms in this range from 20 to 20 lakhs. The length of sperm is 5 microns. It is divided into three parts – head, neck and tail. Sperm survive in the body for 30 days, whereas in women they survive only for 72 hours after intercourse. The testicles are filled with a type of fluid which is called seminal fluid.
Testes are an oval organ, which is located outside the abdominal cavity of men. A man has two testicles. The testicles are the primary reproductive organ in men. The main function of the seminal vesicle is to produce male sex cells or male gametes called 'sperm'. It also secretes the male sex hormone ‘testosterone’. The testicles of a man continue to produce sperms throughout his life after puberty.The testicles have two main functions:
producing semen (which contains male genes)
producing testosterone (the male's initial sex hormone)
Epididymis in male reproductive organs
It is a 6-meter-long coiled tube which is located behind each testicle. It remains well connected to the testicles. One end of it remains attached to the testicle and the other end extends beyond the epididymis to form the vas deferens. The epididymis serves as the main storage site of sperms. Apart from this, maturation of sperms also takes place in the epididymis. Sperms become active here.
Vas deferens in male reproductive organs
It is a thin tube whose walls are made of muscles. Sperms reach the vas deferens from the epididymis. The vas deferens connects the epididymis to the seminal vesicles. It is a thin tube whose walls are made of muscles. Sperms reach the vas deferens from the epididymis. The vas deferens connects the epididymis to the seminal vesicle. These work to propel the sperms forward.
Seminal vesicle in male reproductive organs
It is a structure with a pair of thin muscular walls. These are lobed structures. It is situated above the prostate glands. The seminal vesicles on both sides together form the ejaculatory duct. A type of sticky substance is secreted from the seminal vesicles.
Prostate Gland in male reproductive organs
It is connected from the urethra to the urinary bladder. Its shape is like a round betel nut. Both the prostate glands unite to form a common prostate gland. It contains about two dozen tubes which open into the urethra. A type of fluid is secreted from the prostate which is called prostate fluid. This fluid provides a specific smell to the semen. Prostatic fluid mixed with seminal fluid and reaches the urethra.

Prostatic fluid mixed with seminal fluid and reaches the urethra.
Penis in male reproductive organs
Penis is the sexual organ of men. Sperm reaches the female reproductive system only through the penis. Urethra starts from the urinary bladder and passes through the penis and opens in the upper part of it. There is excessive blood supply to the penis. Along with this, its muscles are also of specific type. Which gives it hardness. The penis expels the semen out of the body and into the vagina of the female. Penis is the sexual organ of men.

Conclusion
The male reproductive organs are responsible for the production and transport of gametes, the fertilization of these gametes, and the development and nutrition of the resulting embryo and fetus. male reproductive organs It is a complex system consisting of many organs and structures including the gonads (testes in males and ovaries in females), reproductive tract (uterus, fallopian tubes and vagina in females and vas deferens, epididymis and seminal vesicle in males). The number of sperms in this range from 20 to 20 lakhs. The length of sperm is 5 microns. It is divided into three parts – head, neck and tail. Sperm survive in the body for 30 days, whereas in women they survive only for 72 hours after intercourse. The testicles are filled with a type of fluid which is called seminal fluid.
