Human Reproduction System

Reproduction is the biological process by which new individual organisms are produced. Reproduction is a fundamental feature of all know life,each individual organism exists as the result of production.
Male reproductive systems ar testicles,epididymis,corpus cavernosa,foreskin,frenulum,urethral opening,glans penis,corpus spongiosum,penis and scrotum.Female reproductive systems are pubic hair,clitoral hood,clitoris,labia majora,labia minora,perineum.
The production of gametes takes place within the gonads through a process known as gametogenesis.gametogenesis occurs when certain types of germ cells undergo meiosis to split the normal diploid number of chromosomes in humans (n=46) into haploids cells containing only 23 chromosomes. In males this process is known as spermatogenesis and takes place only after puberty in the seminferous tubules of the testes. The immature spermatozoon or sperm are then sent to the epididymis where they gain a tail and motility. Each of the origins diploid germs cells or primary spermatocytes forms four functional gametes which is each capable of fertilization. It has long been understood that in females, unlike males, all of the primary oocytes ever found in a female will be created prior to birth and that the final stages of ova production will then not resume until pubery. However, recent scientific data has challenged that hypothesis. This new data indicates that in at least some species of mammal oocytes continue to be replenished in females well after birth.
