Gametogenesis in Humans (3)

Oogenesis(1)

It takes place in the ovaries

Oogenesis (2)

Oogonium (diploid) only produces one functional secondary oocyte (haploid) and three non-functioning polar bodies after me

Oogenesis (3)

Secondary oocytes are large and spherical in shape

Oogenesis (4)

After meiosis I, one secondary oocyte and one polar body is produced

Oogenesis (5)

Meiosis II is only completed when a sperm fertilises the secondary oocyte

Oogenesis (6)

Secondary oocyte does not undergo differentiatio

Oogenesis (7)

The production of the secondary oocyte is not continuous

Oogenesis (8)

The production of the secondary oocyte starts in the female foetus and remains dormant when the baby is born

Oogenesis (9)

The production of the secondary oocyte continues once the female reaches puberty and stops during menopause

Oogenesis (10)

Only one secondary oocyte is released from the ovaries at every menstrual cycle
