FERTILIZATION OF MOUSE OVA IN VITRO

—Mini Review— The early history of the TYH medium for in vitro fertilization of mouse ova

The TYH medium was first reported as a medium for in vitro fertilization (IVF) of mouse eggs with epididymal spermatozoa, by Toyoda, Yokoyama and Hosi, in 1971. It was a modified Krebs-Ringer bicarbonate solution, supplemented with glucose, Na-pyruvate, antibiotics and bovine serum albumin. In TYH medium, almost all eggs are fertilized within 1 h, if the spermatozoa are pre-incubated for 2 h be...

P-87: High Fat Diet Affects In Vitro Maturation and In Vitro Fertilization of Mouse Oocytes

Background: Physiological effects of obesity are increasingly common in women of reproductive age and are associated with infertility. Obese women have dysfunction in hypothalamic-pituitary-ovarian axis, menstrual cycle and are up to three times more likely to have decreased oligo-/anovulation. The purpose of present study was to evaluate the high fat diet on IVM and IVF outcomes in mouse. Mate...

P-67: Quantitative Expression of Pluripotency Specific-Genes in Mouse Blastocysts Produced by In Vitro Fertilization

Background: The efficiency of in vitro fertilization (IVF) is still low to be developed to blastocyst stage probably because of environmental conditions. It is likely that in vitro environment can not exactly mimic in vivo environment due to differences in media, metabolic content, atmospheric composition, temperature and pH. Therefore it may affect embryo quality by changing in embryo gene exp...
