Male reproductive system diagram

The purpose of the organs of the • To produce, maintain, and transport • To discharge sperm within the female reproductive tract during sex • To produce and secrete male Unlike the • Penis : This is the male organ used in sexual intercourse. It has three parts: the root, which attaches to the wall of the The body of the penis is cylindrical in shape and consists of three circular shaped chambers. These chambers are made up of special, sponge-like tissue. This tissue contains thousands of large spaces that fill with Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm). When the penis is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm. • Scrotum: This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a "climate control system" for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth or farther away from the body to cool the temperature. • Testicles (testes): These are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have...

• Glans: Also known as the head of the penis, this bulbous, sensitive structure is covered with a loose layer of skin called the foreskin ( prepuce). The foreskin is sometimes removed in a surgical procedure known as • Urethra: This is the tube that runs the length of the penis through which semen and urine exit the body. The opening at the head itself is called the meatus. • Shaft: Also known as the corpus, this section of the penis is made of three columns of spongy tissue, two of which fill with blood to enable erections (called the corpus cavernosa) and the other of which ( corpus spongiosum) supports the urethra and keeps it open during erections. • Root: Also known as the radix penis, this is the base of the penis that is attached to the pelvis and stabilized by connective tissues known as The scrotum is a loose, pouch-like sack of skin situated below the penis that houses the testes ("balls"). The scrotum maintains the ideal temperature for sperm to survive. It does so through nerves within the skin that cause the scrotum to shrink and become wrinkly when it is cold (increasing the temperature) or relax and loosen when it is warm (reducing the temperature). The vas deferens, also known as the sperm duct, is a long, thin tube that starts at the epididymis and connects to a passageway known as the ejaculatory duct. During orgasm, powerful muscular contractions will propel sperm from the vas deferens, where it will combine with various fluids to form semen. • Seminal v...

For men, the external reproductive organs include: • Penis: This tubular, muscular organ fills with blood during arousal, thus making sexual intercourse possible. • Scrotum: This pouch-like sac hangs below the penis and encases the testes, or testicles. • Testicles: These two oval shaped organs produce sperm cells and testosterone. While all men are born with all of their sexual organs, they don’t begin to function fully until puberty. The average age of puberty for males is around 12. During this time, hormone changes affect a boy’s gonads and create lasting changes that have typically been viewed through history as “when a boy becomes a man.” This process has many effects, such as growth in stature, muscular development, and hair growth on the genitals and face. In terms of reproduction, puberty signals the time when a man has fully-functioning sexual organs and is capable of fathering an offspring. The male testes produce spermatozoa (more commonly referred to as sperm), which are released at sexual climax, or orgasm. This is known as ejaculation. The sperm leaves the penis in a mixture of secretions designed to nourish and transport the cells into the female reproductive system for procreation. There are up to 750 million sperm cells contained in a single ejaculation, but it only takes one sperm cell to fertilize a woman’s egg. The testes also produce the hormone testosterone, which is directly absorbed into the bloodstream. Along with regulating sperm production and m...

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 scrotum is the thick-skinned sac that surrounds and protects the testes. The scrotum also acts as a climate-control system for the testes because they need to be slightly cooler than body temperature for normal sperm development. The cremaster muscles in the wall of the scrotum relax to allow the testes to hang farther from the body to cool or contract to pull the testes closer to the body for warmth or protection. The epididymis consists of a ...

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. Anatomy of the Male Reproductive System Scrotum 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. The smooth muscles that make up the scrotum allow it to regulate the distance between the testes and the rest of the body. When the testes become too warm to support spermatogenesis, the scrotum relaxes to move the testes away from the body’s heat. Conversely, the scrotum contracts to move the testes closer to the body’s core heat when temperatures drop below the ideal range for spermatogenesis. Testes The 2 Epididymis The Spermatic Cords and Ductus Deferens Within the scrotum, a pair of spermatic cords connects the testes to the abdominal cavity. The spermatic cords contain the ductus deferens along with nerves, veins, arteries, and lymphatic vessels that support the function of the testes. The Seminal Vesicles The Ejaculatory Duct The ductus deferens passes through the prostate and joins with the urethra at a structure known as the ejaculatory duct. The Urethra ...

For this biological process to be carried out, certain organs and structures are required in both the male and the female. The source of the ova (the female germ cells) is the female At copulation, or This articles describes the organs, both male and female, that are involved in human reproduction. The reproductive process itself is covered in other articles. For a detailed discussion of the series of changes that occur in a woman’s body as her fetus develops, see see see see

Overview The male reproductive system consists of internal and external organs. These organs help you have sexual intercourse and pee. What is the male reproductive system? The male reproductive system includes a group of organs that make up the reproductive system and The male reproductive system contains internal and external parts. Internal parts are inside your body, and external parts are outside your body. Together, these organs help you urinate (pee), have sexual intercourse and make biological children. Function What does the male reproductive system do? The organs that make up the male reproductive system perform the following: • Produce, maintain and transport sperm cells and semen. Sperm cells are male reproductive cells. Semen is the protective fluid around sperm. • Discharge sperm. • Produce and secrete male sex hormones. How does the male reproductive system function? The entire male reproductive system depends on • Follicle-stimulating hormone (FSH). Your • Luteinizing hormone (LH). Your pituitary gland also makes LH. LH is necessary to continue the process of spermatogenesis. • Testosterone. Testosterone is the main sex hormone in people AMAB. It helps you develop certain characteristics, including muscle mass and strength, fat distribution, bone mass and sex drive (libido). Anatomy What are the external parts of the male reproductive system? Most of the male reproductive system is on the outside of your abdominal cavity or pelvis. The external body parts o...
