INTRODUCTION
Oogenisis is creation of an ovum.It is the female process of gametogenesis. The mitotic phase of human germ cells in females terminates at birth and by 5th month of fetal life. All oogenia have entered their first mitotic division to become primery oocyte. At puberty about 200,000 germ cells are available for reproductive life
Ooocyte deliver half of chromosomal complement to an embryo. However maternal and paternal genomic contribution is not the same. Ooocyte transmit not only genomic maternal but also mitochondrial DNA to the embryo which is majorly affected in aged oocytes
