    The ability to generate mature oocytes in the laboratory is an invaluable tool for reproductive research, and may find potential in clinical application for improving fertility treatment. Laboratory matured oocytes can also be produced from cryo-preserved ovarian tissue from young female cancer patients in support of fertility : Natalia Bonner. He has authored 3 books, scientific papers (54 book chapters, peer-reviewed publications and abstracts). Among his many contributions to the field: a) He pioneered the technique of in vitro maturation of oocytes (IVM) for women with ovarian resistance to FSH; b) Reported the role of ZO-1 in trophoblastic cells differentiation in.   Cryopreservation The very first successful mouse embryo cryopreservation (CP) was reported individually from one another by two research groups in the year Twelve months later, the birth of the first calf through frozen embryo was posted. The 1st human pregnancy from a frozen embryo was achieved with the same procedure applied successfully for CP of mouse and cow embryos; .

Both oviducts and a small portion of the uterus are carefully removed and placed in a petri dish containing pre-warmed (37° C) Hepes-buffered Tyrode's lactate (TL. Fertility preservation has become one of the most important and fast growing fields of reproductive medicine.

Although there are several strategies for fertility preservation in female, most of them are still considered experimental. It is important to perfect the existing technologies, but also developing new strategies should be actively sought.

The number of retrieved oocytes was somewhat lower (average ); however, the high maturation rate has resulted in vitrification of one to three oocytes per patient.

The recent literature supports the shift toward vitrification of human oocy It should be stressed that the efficacy of this approach is low as only oocytes are Cited by:   This book can be found in: Science, Technology & Medicine > Medicine > Pre-clinical medicine > Human reproduction, growth & development zoom Preservation of Human Oocytes: From Cryobiology Science to Clinical Applications - Reproductive Medicine and Assisted Reproductive Techniques Series (Hardback)Pages: have been conducted with vitrified metaphase-II human oocytes.

Keywords: clinical outcome, human, oocyte, survival, vitrification, Introduction The cryopreservation of oocytes constitutes a major step forward in assisted reproductive technologies after representing a serious challenge for many years. The use of IVM in assisted reproductive technology continues to increase around the world.

The major benefit of IVM is that significant numbers of oocytes can be collected from ovaries without recourse to ovarian stimulation.

This reduces the costs, time, and risks associated with conventional IVF. tion, human embryo freezing has become a requirement demanded by the human fertility therapy procedure. Initially, because of low embryo implant rates procedures that stimu-lated many follicles were used to obtain many oocytes and consequently generate many embryos to make up for their lack of vitality.

This strategy increased not only pregnancy. In Vitro Maturation of Human Oocytes - CRC Press Book The use of IVM in assisted reproductive technology continues to increase around the world.

The preservation of the female portion of livestock genetics has become an international priority; however, in situ conservation strategies are extremely expensive. Therefore, efforts are increasingly focusing on the development of a reliable cryopreservation method for oocytes, in order to establish ova banks.
