Comments The female Keimbahn also has preferential sites for GC loss: Many oocytes in rat and mouse degenerate preferentially in pachytene and diplotene stage of the meiotic prophase. The same phenomenon was stated by Baker (’72) in the perinatal human: “Between the 5th month p.c. and the time of birth the population of oocytes declines by some 65% to 2,000,000 in the human ovary.”
