Article : THE FEMALE REPRODUCTIVE SYSTEM

WHAT IS A "TRUE EGG"?

“Eggs” are produced in the ovaries, BUT these are not "true eggs" yet, and will never complete meiosis (a special type of cell division) and become "true eggs" unless OR until they are first fertilized by a sperm. Within the ovary, a follicle consists of one potential egg cell surrounded by special cells to nourish and protect it. HOW MANY EGGS DOES A WOMAN ACTUALLY HAVE? A human female typically has about 400,000 follicles/potential eggs, all formed before birth. Only several hundred (about 480) of these “eggs” will actually ever be released during her reproductive years. Normally, in humans, after the onset of puberty, due to the stimulation of follicular-stimulating-hormone (FSH) one “egg” per cycle matures and is released from its ovary. One month the left ovary will release a potential egg and the next month the right ovary will release a potential egg.
