International Yearbook of Nephrology 1992s still low. The quality of oocytes after IVM appears to be suboptimal because embryos resulting from IVM show more frequent developmental block and transfer of such embryos results in low implantation and clinical pregnancy rates. Recent research advances, especially in the patient preparation, sma

Assays for Vertebrate Sperm Chemotaxis,cially that of herring, was shown to release proteins that initiate sperm motility close to the egg micropyle (.,.), thus serving a role functionally similar to that of a sperm chemoattractant. Recently, allurin, a 21-kDa protein demonstrated to be a sperm chemoattractant, was isolated from . egg je

Detection of Centrosome Structure in Fertilized and Artificially Activated Sea Urchin Eggs Using Imsea urchin eggs, Boveri showed elegantly that dominant centrosome material is contributed by sperm. He showed that sperm centrosomes reorganize after pronuclear fusion and separate to the mitotic poles to form the mitotic apparatus during cell division. Moreover, he showed that sea urchin eggs ferti

In Vitro Maturation and Fertilization of Pig Oocytes,e atypical with regard to regulating mechanisms of oocyte maturation and fertilization. The mechanisms for fertilization in domestic animals such as pig and cattle may be more similar to low vertebrates and human than the mouse (.). Therefore, porcine oocytes have now become an important model for s
