Human reproductive system , organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are 1 liberation of an ovum , or egg , at a specific time in the reproductive cycle, 2 internal fertilization of the ovum by spermatozoa, or sperm cells, 3 transport of the fertilized ovum to the uterus , or womb, 4 implantation of the blastocyst, the early embryo developed from the fertilized ovum, in the wall of the uterus, 5 formation of a placenta and maintenance of the unborn child during the entire period of gestation , 6 birth of the child and expulsion of the placenta, and 7 suckling and care of the child, with an eventual return of the maternal organs to virtually their original state.

The testes are the primary reproductive organs and generate sperm cells through a process called spermatogenesis. The glands of the male reproductive system produce sperm and seminal fluid. The prostate gland, the seminal vesicles, and the bulbourethral glands contribute seminal fluid to semen, which carries and protects the sperm. During sexual intercourse, semen moves through a series of ducts to deliver the semen directly into the female reproductive system. The testes or testicles are the male gonads and sit below the penis within a sac called the scrotum.

The reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic. Due to its vital role in the survival of the species, many scientists argue that the reproductive system is among the most important systems in the entire body. The male reproductive system consists of two major parts: the testes, where sperm are produced, and the penis, according to Merck Manuals. The penis and urethra belong to both the urinary and reproductive systems in males. The testes are carried in an external pouch known as the scrotum, where they normally remain slightly cooler than body temperature to facilitate sperm production. The external structures of the female reproductive system include the clitoris, labia minora, labia majora and Bartholin's glands, according to the Cleveland Clinic. The major internal organs of the female reproductive system include the vagina and uterus — which act as the receptacle for semen — and the ovaries, which produce the female's ova.

Producing and Delivering Sperm: The Male Reproductive System

The male reproductive system includes the penis, scrotum, testes, epididymis, vas deferens, prostate, and seminal vesicles. The penis and the urethra are part of the urinary and reproductive systems. The scrotum, testes testicles , epididymis, vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system. The penis consists of the root which is attached to the lower abdominal structures and pelvic bones , the visible part of the shaft, and the glans penis the cone-shaped end. The opening of the urethra the channel that transports semen and urine is located at the tip of the glans penis. The base of the glans penis is called the corona. In uncircumcised males, the foreskin prepuce extends from the corona to cover the glans penis.

The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen. These reproductive organs also work together to deliver semen out of the body and into the vagina where it can fertilize egg cells to produce offspring. The scrotum is a sac-like organ made of skin and muscles that houses the testes. It is located inferior to the penis in the pubic region. The scrotum is made up of 2 side-by-side pouches with a testis located in each pouch.


Therefore, the two main functions of the testicles are: producing sperm. (​approximately 1 million per hour) and male sex hormones (e.g. testosterone).

Male Reproductive Function and Semen

These organs do the following jobs within your body:. The male reproductive system is made up of internal inside your body and external outside your body parts. Together, these organs help you urinate rid your body of liquid waste materials , have sexual intercourse and make children. Most of the male reproductive system is located outside of your abdominal cavity or pelvis. The external parts of the male reproductive system include the penis, the scrotum and the testicles.

Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm or spermatozoon , combine with the chromosomes in one female gamete, called an oocyte. The paired testes are a crucial component in this process, as they produce both sperm and androgens, the hormones that support male reproductive physiology. In humans, the most important male androgen is testosterone.
