These tubules are also sex hormone-producing cells masculinas.Los testicles are located outside the abdominal cavity and are covered by a fold of skin called the scrotum.
- The breeding ways: They are called so the tubes that carry sperm collected and abroad. These are: · Epididymis. Duct formed by the seminiferous tubules of each testicle. Sperm complete the maturation process that will make them suitable for all fecundacion.Si seminiferous tubules are placed one after another, they reach a length of 200 meters. · Vas deferens. Constituyenn the continuation of the epididymis and ascends into the abdomen. Serves as storage of sperm produced in the testicles until he leaves. · Urethra. Ductus also belongs to the urinary tract and the last part of the journey is housed inside the penis.
- The penis: copulatory organ masculino.Constituido two spongy mass of tissue cracteristico, called corpora cavernosa, are placed above the urethra. It is surrounded by another section of tissue, the corpus spongiosum, which widens at its end and forms the glans, which is covered by a fold of skin called the foreskin.
During copulation, arteries, blood pressure injected into the corpora cavernosa, which makes these grow in size causing penile rigidity and facilitating their introduction into the female vagina.
- Gland: Associated apparatus are male accessory glands, whose function secretions mix with sperm to form semen or facilitate penetration. · Seminal vesicles. Located behind of the bladder urine and empties into the vas deferens. It secretion, spermatic fluid, containing glucose, a nutrient for the sperm. · Prostata. Located underneath of the bladder and urinary secretion, prostatic fluid, is made up of substances that protect the sperm against the acidity of the vagina. · Cowper's glands. This is a pair of glands that are situated at the base of the penis. The function of these glands is to secrete a liquid lubricant.
