The organs and structures of the male reproductive system give men the ability to fertilise a woman's egg (ovum) to provide a child. The scrotum changes size to keep up the correct temperature. The spermatozoa are released into the epididymis where they full their maturation and become able to transfer on their own. When the male ejaculates throughout intercourse, semen is deposited into the female's vagina. This fluid enters the urethra during sexual arousal prior to ejaculation to organize the urethra for the circulation of semen.

Below are some examples of disorders that affect the male reproductive system: The primary hormones involved within the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.

The production of testosterone brings about many bodily adjustments. The sperm released throughout ejaculation must first swim via the vagina and uterus and into the fallopian tubes the place they could discover an oocyte. How Does the Male Reproductive System Perform? The sperm use their tails to push themselves into the epididymis, where they complete their development.

The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a supply of vitality to help them move. The pores and skin of the penis is loose and elastic to accommodate adjustments in penis size throughout an erection. Urethra: The urethra is the tube that carries urine from the bladder to outdoors of the physique.
