objective: basal fsh levels reflect ovarian response and more formed embryos. we investigated a reliable fsh range to retrieve more oocytes and embryos. materials and methods: two hundred patients in art cycles underwent this study from apr 2007 to sep 2008. patients were divided in three groups based on value of fsh: group a≤8 iu/ml, 8 iu/ml < group b≤10 iu/ml, group c>10 iu/ml and results of ...

INTRODUCTION Today, oocyte donation has become well established, giving rise to thousands of children born worldwide annually. The introduction of oocyte cryopreservation through vitrification allows the introduction of egg banking, improving the efficiency and comfort of oocyte donation. Moreover, the vitrification technique can now enable autologous donation of oocytes to prevent future infer...

STUDY QUESTION What is the nature of the relational status, reproductive choices and possible regret of a pioneer cohort of women that either considered or actually performed oocyte banking for anticipated gamete exhaustion (AGE)? SUMMARY ANSWER Only half of the women who banked oocytes anticipate using them in the future but the experience with oocyte banking is overwhelmingly positive, with...

BACKGROUND Assisted Reproductive Technology (ART) reports generated by the Centers for Disease Control and Prevention (CDC) exclude embryo banking cycles from outcome calculations. METHODS We examined data reported to the CDC in 2013 for the impact of embryo banking exclusion on national ART outcomes by recalculating autologous oocyte ART live birth rates. Inflation of reported fresh ART cycl...

Interest in oocyte cryopreservation has recently increased with the growing importance of in vitro embryo production, nuclear transfer, and gene banking (Gordon, 1997; Andrus et al., 2000). A relatively recent approach to achieve rapid freezing without the use of expensive freezing devices is called vitrification. Vitrification is defined as the physical process by which a highly concentrated s...

Is there a really need to validate oocyte vitrification technique in an ART laboratory before establishing it in daily practice? Validation of micromanipulationbased technique, in this case oocyte vitrification, is essential prior to enlarging its use to routine practice. Oocyte vitrification is a new worldwide used technique and legal recently in France. This micromanipulation needs to be perf...
