The male reproductive organs are testes, vas deferens, accessory glands, scrotum and penis. 1. Testes: The testes are located in the scrotum, one on each side of the body. The main function of the testes is to secrete androgens and produce sperm. PEAK VASCULATORY DUCTS: The vas deferens includes the epididymis, vas deferens, ejaculatory ducts and urethra. The epididymis is at the posterior margin and upper end of the testis, and its function is to provide nutrients for the growth and maturation of spermatozoa and storage of spermatozoa. The vas deferens is about 40cm long and its function is to transport sperm. The ejaculatory duct is about 2cm long and is the tube that carries sperm in men. The urethra is the tube that leads from the bladder to the outside of the body. 3. Accessory glands: The accessory glands include the seminal vesicle glands, prostate glands, and urethral bulbous glands. The seminal vesicle glands are located at the base of the bladder, on the outside of the vas deferens, and their main function is to secrete seminal vesicle fluid. The prostate gland is located at the base of the bladder and mainly secretes prostatic fluid, its main function is to ensure sperm activity and fertilization ability. The urethral bulbourethral glands are buried in the urogenital diaphragm, and their function is to secrete egg-white alkaline fluid, which is involved in the composition of semen. 4. Scrotum: The scrotum consists of skin and serves to store the testes. 5. Penis: The penis consists mainly of a urethral corpus cavernosum and two penile corpus cavernosums, and it has the function of sexual intercourse, as well as urination and ejaculation. To summarize, if there are male reproductive system diseases, you should seek medical treatment in time.
