PCOS: Polycystic Ovary Syndrome; t2PB = time of appearance of 2 polar bodies; t2 P N = time of appearance of 2 pronuclei; tPNF = time by which both pronuclei had faded; t2 = time of division to 2-cell stage; t3 = time of division to 3-cell stage; t4 = time of division to 4-cell stage; t5 = time of division to 5-cell stage; t6 = time of division to 6-cell stage; t2 P N-2PB = duration of the period from appearance of 2 polar bodies to appearance of 2 pronuclei; tPNF-2 P N = duration of the period from appearance of 2 pronuclei to pronuclear fading; t2-PNF = duration of the period as 1-cell; t3-2 (CC2) = time of the second cell cycle; t4-t3 (S2) = time of synchrony of the second cell cycle.
