    When a male ejaculates during intercourse or masturbation, are the both testicles used in this process, or only one, be it left or right? Neither of the testicles are involved in ejaculation! A structure called the epididymis, found above the testicles in the scrotum, is the one you have to thank for letting the sperm out during ejaculation. The testicles are where sperm are produced in a process scientists call spermatogenesis.

    Men’s Health Q&A- Male reproductive system and sperm

    Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes GAH-meetz , are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes meets an egg, this fertilized egg is called a zygote ZYE-goat. The zygote goes through a process of becoming an embryo and developing into a fetus. The male reproductive system and the female reproductive system both are needed for reproduction.

A year-old man was referred to me by his primary care physician for an infertility workup.
