Explanation:
Detailed explanation-1: -When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male’s body through his urethra-this process is called ejaculation. Each time a guy ejaculates, it can contain up to 500 million sperm.
Detailed explanation-2: -Increased testosterone production is what causes boys to develop deeper voices, bigger muscles, and body and facial hair. It also helps the testes produce sperm, and it plays a role in speeding a boy’s growth in height during puberty.
