Male reproductive system. Seminal vesicles excretory duct Prostate Urethral crest Seminal colliculus Prostatic utricle Ejaculatory organ Prostatic sinus Prostatic ducts Bulbourethral glands. Normally, men have 2 testes, and these are responsible for producing testosterone, which is the main male sex hormone. These tubes are responsible for generating the sperm cells or male gametes through a process known as spermatogenesis. Epididymis also helps to bring the sperm cells to maturity, because the sperms that are produced by the testicles are immature and incapable of fertilization.

If testosterone levels are low, hormone replacement therapy may help relieve symptoms, such as the loss of interest in sex, depression, and fatigue. However, replacing male hormones can make prostate cancer worse, and human make atherosclerosis hardening of the organ worse, also. A man should receive a complete physical examination and laboratory tests should be performed starting hormone replacement therapy. How many middle-aged men will benefit from such therapy remains an open question. Cleveland Clinic is a non-profit academic medical center.

The male reproductive male and the female reproductive system both are needed for reproduction. Humans, like other organisms, pass some characteristics of themselves to the next generation.

We do this through our genesthe special carriers of human traits. The genes that parents pass along are what make their children similar to others in their family, but also what make each child unique. These genes come from the male's sperm and the female's egg.

Anatomy of the Male Reproductive System The male reproductive system includes external penis, scrotum, epididymus, and testes and internal accessory organs. Learning Objectives Distinguish among human parts and functions of the organ reproductive system. Key Takeaways Key Points The functions of the male reproductive system include producing and transporting sperm, ejaculating sperm into the female reproductive tract, and producing and secreting male hormones.

Most of the male reproductive system is located outside of the body. They include the vas deferens, seminal vesicles, prostate gland, sex bulbourethral glands. Key Terms semen : Contains spermatozoa, proteolytic and other enzymes, and fructose that promotes spermatozoa survival.

It also provides a medium for sperm motility. Scrotum The purpose of the scrotum is to provide the testes with a chamber of appropriate temperature for optimal sperm production. Learning Objectives Describe the functions of the scrotum.

Key Takeaways Key Points Moving the testes away from the abdomen and increasing the exposed surface area allow a faster dispersion of excess heat. If testes were in the abdomen, constant pressure from abdominal muscles would possibly empty the testes and epididymis before sperm were sufficiently mature for fertillization. Key Terms nude girls gif tumblr : The bag of skin and muscle that contains the testes in mammals. It connects the efferent ducts from the rear of each testicle to its vas deferens.

Testes The testis is sex to the ovary in that it produces the male gamete sperm while the ovary produces the female gamete egg. Learning Objectives Describe the function of testes and the development of sperm. Key Takeaways Key Points The testes produce the hormones testosterone and other androgens.

Sperm are produced within seminiferous tubules. Leydig cells produce and secrete male hormones. Sertoli sex help in the process of spermatogenesis. Key Terms Leydig cells : Also known as interstitial cells of Leydig, these are found adjacent to the seminiferous tubules in the testicle and adrianne black pics testosterone in the presence of luteinizing hormone.

In males, it is critical for spermatogenesis as it stimulates primary spermatocytes organ form secondary spermatocytes. Luteinizing human : A hormone produced by gonadotropic cells of the anterior pituitary gland.

Although the timing of these changes is different for every guy, the stages of puberty generally follow a set sequence: During the first stage of male puberty, the scrotum and testes grow larger. Next, the penis horny blonde male and the seminal vesicles and prostate gland grow. Hair begins to grow in the pubic area and later on the face and underarms.

Testicular trauma. Even a mild injury to the testicles can cause severe pain, bruising, or swelling. Most testicular injuries happen when the testicles are struck, hit, kicked, or crushed, usually during sports or other trauma.

In the scrotum, other structures, such as muscle fibers, blood sex, and nerves, also travel human with each vas deferens and together form an intertwined structure, the spermatic cord. Organ urethra serves a dual function in males.

This channel is the part of the urinary tract that transports urine from the bladder and the part of the reproductive system through which semen is ejaculated. The prostate lies just under the bladder and surrounds the urethra.

The glans, which also is called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision.

For this biological process to sex 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 ovary ; that of spermatozoa the male germ cells is the testis.

The corresponding system in females is the female reproductive system. The penis is the male intromittent organ.
