Men's testicles, as well as women's ovaries produce sex hormones - androgens and the most important of these hormone testosterone.The testicles also produce seminal fluid.In the developing fetus, testosterone promotes the development of male sex organs.During puberty, this hormone promotes the production of sperm and the development of secondary sexual characteristics such as body hair and on her face, a change in the vocal cords and muscle growth.testicular size ranges from 2.5 - 4.5 cm in length and about half of this width.For most men the left testicle hangs lower than the right.

testes constantly produce sperm.In fact, they produce it at an incredible rate - about 1,000 sperm per second.However, men

sperm mature within 70 - 75 days.Young adult man only when one ejaculation lose about 300 - 500 million sperm.

Inside testicular spermatozoa are produced in the spiral tube called semyavyvodya-forming tubules.Depleted in these young sperm cells come in a large-sized spiral tube (epidedimis), where co

mplete their development.Mature sperm accumulate in the epi-dedimise and seminiferous tubules, which are a long tube coming out of each testicle.According to this tube from testicular sperm enter the urethra, and through it - to the outside.At the point where the seminiferous tubules are part of the urethra there are several glands.Two small glands (seminal vesicles) reach a length of 5 cm. They produce a liquid, highly enriched with fructose, which is a kind of sugar.Fructose promotes the activity of sperm and their ability to move quickly in a humid environment.Following the seminal vesicles, the prostate gland is located.In shape and size it resembles a chestnut.The secret, which it produces, similar to the alkaline emulsion.It affects the structure, taste and smell of sperm.Her alkaline neutralize some acids, such as within the male urethra and vagina in the female.

Iron Cooper is located below the prostate.During sexual arousal, it produces a few drops of clear secretions that accumulates at the entrance to the urethral orifice and a lubricant, which neutralizes the acidic environment inside the urethra and makes it easier to pass on her sperm during ejaculation.This secret is often contain viable sperm, and therefore a woman can get pregnant even if the man during ejaculation takes his penis out of a woman's vagina.
