Anatomy of the Male Reproductive System Testes. The 2 testes, also known as testicles, are the male gonads responsible for the production of sperm and testosterone. The testes are ellipsoid glandular organs around 1.5 to 2 inches long and an inch in diameter.

The Lymphatic and Immune Systems The male and female gonads (testes and ovaries) produce sex cells (ova and sperm) and the hormones necessary for the proper development, maintenance, and functioning of the organs of reproduction and other organs and tissues. The reproductive system comprises the reproductive organs. In the male, the organs include the testes, accessory ducts, accessory glands, and penis. In the female, the organs include the uterus, uterine tubes, ovaries, vagina, and vulva.

- The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete hormones and are considered to be endocrine glands.

- 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.perm produced in the testes moves into the epididymis to mature before being passed on through the male reproductive organs. The length of the epididymis delays the release of the sperm and allows them time to mature.

- This process, known as spermatogenesis, takes place within the tubules inside the lobules of the testes. The sperm will remain in the tubules of the testes until they are expelled through the epididymis during ejaculation. Like the ovaries, the testes also function as glands. They release the male hormone testosterone, which causes development of male sex characteristics, like a deep voice, broad shoulders, and body hair. So, if you like a deep voice, you now know what's responsible for making that happen. The gonads hard at work!

Male Reproductive System continued... The internal organs of the male reproductive system, also called accessory organs, include the following: Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes.It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.pididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes.

Conception and Development. In the male fetus, an enzyme, 5 alpha reductase, converts testosterone to dihydrotestosterone. The genital tubule instead becomes a penis, while the urogenital membrane fuses to become the scrotum. See also Epigenesis and The Maternal Effect in the last section.

The Male Body The basic function of the male sexual and reproductive system is to produce reproductive cells called sperm. Sperm leaves the body through a mixture of body fluids called semen. When males are sexually excited (aroused), the penis becomes larger and stiffer and it usually stands out from the body. This is called an erection.

The Male Reproductive System Testicles (testes) — The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm.

Human Reproductive System 1 The male reproductive system consists of sexual organs, accessory glands, and a series of duct systems that provide a pathway for fertile sperm cells to exit the body. 2  Male reproductive structures include the penis, testes, epididymis, seminal vesicles, and prostate gland.

Which organs are responsible for producing fluid to give sperm nourishment and motility? bulbourethral glands. The male reproductive system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. It consists of:1. Testes- produces sperm and the hormone testosterone2. Scrotum- pouch enclosing the testes keeping the sperm at an optimum temperature.3. Vas deferens- tube that carries sperm away from the testes.4. Prostate gland- adds lubricating and other fluids to the sperm.5.

Urology The organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate and penis). The urinary and reproductive tracts are closely linked, and disorders of one often affect the other.

Fertilization Two mechanisms can operate to ensure that only one sperm fertilizes the egg. In many cases, a rapid depolarization of the egg plasma membrane, which is caused by the fusion of the first sperm, prevents further sperm from fusing and thereby acts as a fast primary block to polyspermy.he acrosome reaction that occurs when a mammalian sperm fertilizes an egg. In mice, a single glycoprotein in the zona pellucida, ZP3, is thought to be responsible for both binding the sperm and inducing the acrosome reaction. Note that a mammalian sperm (more...). The acrosome reaction is required for fertilization.

- These organs also work together to deliver semen out of the body and into the vagina where it can fertilize egg cells to produce offspring.... Click to read more below. 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.

- Seminal gland. The seminal gland, more commonly referred to as the seminal vesicle, holds the liquid that mixes with sperm to form semen. Semen combines fluid elements from the epididymis, seminal vesicles, prostate gland, and vas deferens.Each body part plays a key role in semen production.The fluids help the sperm swim towards the egg and keep the sperm nourished during the transit process.he fluid also has clotting properties that make the semen sticky. This ensures that the semen clings inside the vagina long enough for the sperm to travel to the egg. Pain in the lower left section of the abdomen is an indicator that the seminal vesicle is inflamed.

Human Reproductive System Both male and female reproductive organs have internal and external structures. Reproductive organs are considered to be either primary or secondary organs. The primary reproductive organs are the gonads (ovaries and testes), which are responsible for gamete (sperm and egg cell) and hormone production.

Human Reproductive System 1 Testes-Male primary reproductive structures that produce male gametes (sperm) and sex hormones. 2  Scrotum-External pouch of skin that contains the testes. 3  Because the scrotum is located outside of the abdomen, it can reach temperatures that are lower than that of internal body structures.

The testis is a firm, mobile organ lying within the scrotum; the left testis lies slightly lower than the right. The testes are the primary reproductive organs (gonads) in the male, and are responsible for the production of sperm.
