In our study, the yolk at pre-ovulatory stage and zona pellucida after post-ovulation degenerated, which were engulfed by hypertrophied follicular cells as has also been reported for other several species (Tyler and Sumpter, 1996; Thome et al., 2009; Ucuncu and Cakici, 2009).
Membrane structure was continuous and coherent and the zona pellucida (ZP) of control MII oocytes composed of electron dense fibrillar material and completely surrounds the oocyte.

At this stage, biopsy can be performed in two ways: zona pellucida is opened at 3 (rd) cultivation day, and during the next two days TE cells progress towards the hole considering their hatching tendency, so biopsy of TE cells is simplified.

In the laboratory, follicles (3-6 mm) are were aspirated with the aid of a vacuum pump and oocytes with intact zona pellucida were frozen (-18[degrees]C) for later use.
It has been reported that in vitro, sperm with single stranded or denatured DNA bind less or do not bind at all to the Zona Pellucida (ZP) (18) In pigs, spermatozoa with stable chromatin are more likely both to bind to the oviduct and to traverse the reproductive tract in vivo (41), ultimately reaching the oocytes and penetrating the zona pellucida.

Mammalian zona pellucida glycoprotein (ZP) is made up of three sulfated glycoproteins (ZP1, ZP2, ZP3 or ZPA, ZPB, ZPC) that surround the oocyte (7).
Mammalian oocyte are surrounded by a non-cellular layer called the zona pellucida at the time of ovulation.
