WebEnter Prophase of Meiosis 1 (Leptotene, Zygotene, Pachytene, Diplotene, Arrests!) Why does the Primary Oocyte arrest after Meiosis 1? Fails to leave the diplotene stage. Doesn't enter diakinesis for completion of Prophase 1. Enter a "resting stage" which renames the diplotene stage to the dictyate stage. WebEvery fifth section was marked for direct counts of oocytes at pre-diplotene and diplotene stages and four to five ovaries were analyzed at each age. A total of 10 –12 sec-tions per ovary were used for counting. To avoid bias, all ovaries were analyzed without knowledge of age. To avoid double counting of oocytes, only oocytes having a visible
