Developmental characteristics of male reproductive organs




The male reproductive organs are divided into internal and external parts, the internal reproductive organs have testicles, vas vasomy and ancillary glands;




The testes produce sperm, so they are male reproductive organs, and the interstitial cells on the curly tubes in the testes secrete a lot of androgens and a small amount of estrogen, so they are important endocrine organs for men. Before puberty, the testicles are in a childish state, the volume is less than 3 ml, the testicles produce sperm in the cranial tube is narrow and thin, can not see the tube cavity. Around 10 years old, the tube began to develop, the tube wall appeared a small number of sperm cells, about 12 years old, testicles rapidly developed, volume increased to more than 12 ml, the length and twists of the curly fine tube increased, the tube wall of the sperm cells continue to divide and reproduce, and gradually develop into various stages of sperm cells, and finally produce sperm, the same chromocyte secretion androgens.




The sperm produced in the testicles is not yet fully mature, and it continues to absorb nutrients and develop after entering the attached testicles. The vasectopid is attached to the tail of the testicles and is synthesized with the excretion tube of the sac glands, which opens through the prostate to the urethra. Testicular one attached testicle one vasecto a ejaculation tube - the urethra mouth, is the only way to sperm exuberance.
