The human reproduction system produces EGG Ovum and sperm to produce the new generation. The female gamete named as ovum egg is produced by ovary. The release of ovum named as ovulation. In female. The sperm is the gamete produced by testis.

Sperm and eggs can be unbelievably tiny, far smaller than those made by people, or they can be unexpectedly enormous. The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable.

The egg cell , or ovum plural ova , is the female reproductive cell gamete in oogamous organisms. The egg cell is typically not capable of active movement, and it is much larger visible to the naked eye than the motile sperm cells. When egg and sperm fuse, a diploid cell the zygote is formed, which rapidly grows into a new organism. While the non-mammalian animal egg was obvious, the doctrine ex ovo omne vivum "every living [animal comes from] an egg" , associated with William Harvey — , was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reproduced via eggs. Karl Ernst von Baer discovered the mammalian ovum in
