In simple terms, reproduction is the process by which organisms create descendants. This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and a secondary oocyte along with first polar body and corona radiata , the male gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. It is a common misnomer to refer to a woman's gametic cell as an egg or ovum, but this is impossible.
Human Physiology/The male reproductive system
Male Reproductive System (for Parents) - KidsHealth
There are 23 chromosomes in each sperm produced by a human male. In the testicles. Millions of sperm are produced per ejaculation. They produce semen. This is the fluid containing sperm. An adult male manufactures over million sperm cells each day. Human male sperm is made in the testicles.
Male Reproductive System
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".
Sperm is the male reproductive cell. In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid , so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.
