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.
Sperm Production | How is Sperm Produced? | Spermatogenesis
The machinery that makes sperm is a marvel of biology. This article explores the micro world of sperm production and the key factors that affect proper sperm development. Every second, the average man produces 1, sperm adding up to over billion over the course of his life. The machinery that makes sperm is a marvel of biology with a single goal in mind — creating life. A wonder in its own right, the sperm cells is the single densest cell in the male body.
Semen , also known as seminal fluid , is an organic fluid that may contain spermatozoa. It is secreted by the gonads sexual glands and other sexual organs of male or hermaphroditic animals and can fertilize female ova. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". Semen is produced and originates from the seminal vesicle , which is located in the pelvis. The process that results in the discharge of semen is called ejaculation.
Unlike the female genitalia , the male reproductive organs are on both the interior and the exterior of the pelvic cavity. They include:. Sperm production occurs in the testicles.
