In Vitro Development of Porcine Oocytes Following Intracytoplasmic Injection of Freeze-Dried Spermatozoa with Trehalose
The objectives of this study were to investigate the effects of trehalose as a cryoprotectant for porcine freeze-dried spermatozoa, to find the optimal freeze-drying time and storage periods of freeze-dried spermatozoa, and to find out pronuclear formation rates, cleaved rates, and embryo developmen...

| Summary: | The objectives of this study were to investigate the effects of trehalose as a cryoprotectant for porcine freeze-dried spermatozoa, to find the optimal freeze-drying time and storage periods of freeze-dried spermatozoa, and to find out pronuclear formation rates, cleaved rates, and embryo development through intracytoplasmic injection of freeze-dried spermatozoa on porcine oocytes. The survival rates of spermatozoa after freeze-drying with trehalose treatment were significantly higher than those of them without trehalose treatment (p<0.05). The highest survival rates were found at 75 mM trehalose treatment. The longer storage periods after freeze-drying seemed to have a lower survival rates. Development in culture of pig by ICSI with trehalose treatment were significantly higher than those of them without trehalose treatment (p<0.05). Shorter freeze-drying time of spermatozoa was resulted in the highest cleaved rates and embryo development. |
