in vitro maturation of germinal vesicle oocytes in stimulated intracytoplasmic sperm injection cycles

objective: this study evaluated in vitro maturation (ivm) of oocytes in the germinal vesicle (gv) stage in stimulated intracytoplasmic sperm injection (icsi) cycles. materials and methods: a total of 26 women, aged 18 -37 years, who were candidates for icsi at the fatemeh zahra infertility and health reproductive research center in 2007 were recruited for this study. we used the standard long p...

P-217: The Effect of Progesterone on The In Vitro Maturation of Mouse Germinal Vesicle Oocytes Derived from Polycystic Ovary

Background: Polycystic ovary syndrome (PCOS) is characterized by chronic anovulation and hyperandro genism and affects approximately 5-10% of women of reproductive age. In vitro maturation (IVM) of mammalian oocytes has become an efficient method to produce mature oocytes in order to use in assisted reproductive techniques such as in vitro fertilization (IVF), intra cytoplasmic sperm injection ...

Germinal vesicle transfer between fresh and cryopreserved immature mouse oocytes.

BACKGROUND We assessed the maturational competence and the chromosomal pattern of mouse oocytes reconstructed by germinal vesicle (GV) transfer technique using nuclear and/or cytoplasmic components from cryopreserved GV stage oocytes. METHODS From 657 GV oocytes (326 fresh and 331 frozen/thawed), four groups of reconstructed oocytes were obtained by micromanipulation and electrofusion: fresh ...
