Gamete Preservation

Sperm, oocytes, testicular and ovarian tissue cryopreservation studies

Research unit of Gamete preservation

Project leader

 Assoc.Prof.Dr. Kaywalee Chatdarong (DVM, MS.c., Ph.D.)

                The research study related to gamete preservation will mainly focus on the cryobiology of gamete cells and reproductive tissue i.e. sperm, oocytes, testicular and ovarian tissues in companion animals, live and post-mortem endangered wildlife species. The purpose is to improve scientific understanding in this field and to apply this knowledge to the benefit of reproductive management and establishment of genome resource bank. Together with cryobiology research, the other assisted reproductive techniques i.e. in vitro embryo production, culture and laparoscopic embryo transfer will be integrated with the ultimate goal to produce the new offspring especially in endangered wildlife conservation research area.

Mission

To understand and investigate effect of low temperature to gamete cell and reproductive tissue function and survival

To develop high potential short and long term gamete cell and gonadal tissue preservation procedures which are practical under the field condition and in the remote area

To integrate cryobiology research with other assisted reproductive techniques aims to produce the new offspring both in companion and wildlife species

To establish genome resource bank emphasized on  live and post-mortem endangered wildlife species under the collaboration with Thai government agencies such as The Zoological Park Organization and The Royal Forest Department, The Department of National Parks, Wildlife and Plant Conservation, Ministry of Natural Resources and Environment
