Position of the reproductive organs

  • penis
  • testicle

Internal reproductive organs

  • testicle - It produces sperm and testosterone (male sex hormone), which promotes sperm maturation, and the development of a masculine figure and body hair.
  • epididymis - It stores the sperm produced in the testicles.
  • sperm duct (vas deferens) - A tube with a muscular wall. Its peristaltic contractions propel semen forwards during ejaculation.
  • seminal vesicle - It plays an important role in the formation of semen.
  • prostate - It plays an important role in the formation of semen.
  • urinary bladder
  • urethra

Cross section of a testicle

  • testicle - It produces sperm and testosterone (male sex hormone), which promotes sperm maturation, and the development of a masculine figure and body hair.
  • epididymis - It stores the sperm produced in the testicles.
  • sperm duct (vas deferens) - A tube with a muscular wall. Its peristaltic contractions propel semen forwards during ejaculation.
  • seminiferous tubules - Sperm cells develop here.

Penis

  • foreskin - A double-layered fold covering the glans when the penis is not erect. During the erection, it is retracted.
  • vein - During the erection, the outflow of blood is restricted, thus it collects in the cavernous bodies.
  • corpus cavernosum cavernous body - During the erection it gets filled with blood.
  • corpus spongiosum
  • urethra
  • nerve - Its stimulation ensures sexual arousal, erection and ejaculation.
  • artery

Secondary sex characteristics

  • larynx - In men it is larger than in women, thus the male voice is deeper.
  • shoulder
  • breasts - Their primary function is the nourishing of an infant child. It consists of fatty tissue and the mammary gland.
  • hips - Men: Shoulders are generally wider than the hips. Women: Hips are usually wider than the shoulders.
  • pubic hair - Men: Diamond-shaped and covers part of the abdomen. Women: Nearly triangular.
  • body hair

External reproductive organs

  • penis - It is composed of 3 cylindrical bodies of spongy tissue. In addition to its sexual function, the penis acts as a conduit for urine.
  • glans penis - A bulbous structure at the distal end of the human penis.
  • foreskin - Also known as prepuce; a double-layered fold that covers and protects the glans penis. When the penis is erected, the foreskin is usually retracted.
  • scrotum - A suspended sack of skin and smooth muscle tissue that contains the testicles and epididymides. It serves to maintain the optimal temperature for testicles.
