Abstract: (318 Views)
Introduction: To assist save endangered species from extinction and to aid in their care, it is crucial to sustaining their reproductive capacity. The fetus's life and growth processes begin at conception and proceed in accordance with a biological clock's timing. With today's understanding through cryobiology, observing scientific ethics problems and interfering with the clock's operation by stopping its biological time is possible. Practically, it is accomplished by storing the cell at -196 °C, or the temperature of liquid nitrogen, where all metabolic activity ceases. Since 200 years ago, germ cell preservation has been a common practice. Since then, there have been many improvements, particularly for at-risk women. Since then, significant progress has been achieved, and several freezing techniques are being used to preserve ovarian tissue, follicles, and oocytes in women who are at risk of infertility. Different approaches have different levels of success. Among preservation techniques, vitrification performs better and is used more frequently. The cellular configuration of the mammalian oocyte is intricate. This cell's constituent parts are particularly sensitive to osmosis and variations in temperature. For instance, the alterations to the cell membrane that occur during maturation, in vitro fertilization, and the differential between the permeability of water and cryoprotectants can all be mentioned. Oocyte freezing results in a variety of impairments, including a reduction in the quality and viability of cells after thawing.
Conclusion:Recent studies are looking for ways to enhance freezing procedures and raise the caliber of frozen oocytes. The favorable or negative effects of freezing on the oocyte and its potential, or embryo development, are the subject of this review article.
