And inside the ovaries, an important process known as Ogenesis takes place. Now, Ogenesis is the process by which these special stem cells down inside female individuals known as Ogonium or Ogonia, if we're talking about many cells, basically differentiate and eventually develop into the female gamma meets the female sex cells known as X cells or ovum. Now, an ovum is a single excel, but an OVA means many excels. So the major difference between male individuals and female individuals is that in female individuals, all the primary oocytes are formed before that individual is actually born. They are formed during fetal development. So all these stem cells we call ogonia inside our developing fetus basically differentiate into the primary oocyte.
