The reproductive system of an organism, also known as the genital system , is the biological system made up of all the anatomical organs involved in sexual reproduction.

Male Reproductive Function and Semen

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.

Error: This is required. Error: Not a valid value. The male reproductive system contains the external genitals the penis, testes and the scrotum and internal parts, including the prostate gland, vas deferens and urethra. A man's fertility and sexual traits depend on the normal functioning of the male reproductive system, as well as hormones released from the brain. The brain also has an important role in reproductive function, as it controls the release of sex hormones. As with any other part of the human body, things can sometimes go wrong with the male reproductive system, including:.

Name the key hormones secreted by Leydig cells and Sertoli cells of the testes. Know the general structure of testosterone, and describe its biosynthesis, transport, metabolism, and actions. The role for a functional, secreting testis in the formation of male genitalia, the action of male hormones on the brain in early development, and development of the male reproductive system through adolescence and into adulthood were discussed in the previous chapter.

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.

Беккер проехал уже половину пути, когда услышал сзади металлический скрежет, прижался к рулю и до отказа открыл дроссель. Раздался приглушенный звук выстрела.

Фреоновые вентиляторы с урчанием наполняли подсобку красным туманом. Прислушавшись к пронзительному звуку генераторов, Сьюзан поняла, что включилось аварийное питание. Сквозь туман она увидела Стратмора, который стоял внизу, на платформе. Прислонившись к перилам, он вглядывался в грохочущее нутро шахты ТРАНСТЕКСТА. - Коммандер! - позвала Сьюзан. Ответа не последовало. Сьюзан спустилась по лестнице на несколько ступенек.
