So we know, also, that human eggs contain lots of mitochondria, which anyone who paid attention in 8th grade biology should recognize as the powerhouse of the cell—they convert oxygen and nutrients into chemical energy.

Once released—a process known as ovulation, which usually occurs around 2 weeks after the first day of your period—an egg cell has a pretty short life span. In the case of unprotected sex around the time of ovulation, the fallopian tube becomes the venue for fertilization, and the fertilized egg will implant in the uterus.

The female reproductive system provides several functions. The ovaries produce the egg cells, called the ova or oocytes.

Human eggs: 9 fascinating facts

Fertile women release one or more eggs every month, but until now, only fuzzy images had been recorded. The new images were taken by accident by gynaecologist Jacques Donnez while carrying out a partial hysterectomy on a year-old woman. The release of an egg was thought to be a sudden event, but the pictures published in New Scientist magazine show it takes over 15 minutes for the translucent yellow sphere to emerge. Shortly before the egg is released, enzymes break down the tissue in a fluid-filled sac on the surface of the ovary that contains the egg. A reddish protrusion forms and then a hole appears from which the egg emerges. The egg is surrounded by supporting cells, which protect it as it enters the Fallopian tube on its way to the uterus.

The egg cell , or ovum plural ova , is the female reproductive cell, or gamete , in most anisogamous organisms organisms that reproduce sexually with a larger, "female" gamete and a smaller, "male" one. The term is used when the female gamete is not capable of movement non- motile. If the male gamete sperm is capable of movement, the type of sexual reproduction is also classified as oogamous. When egg and sperm fuse during fertilisation , a diploid cell the zygote is formed, which rapidly grows into a new organism.
