Implications of oocyte cryostorage for the practice of oocyte donation.
As the efficiency of oocyte cryopreservation has increased rapidly in recent years, oocytes are currently being stored either in the course of IVF treatments or as a fertility preservation measure. These practices may have an impact on the number of available donor oocytes due to two different dynamics: first, a certain percentage of women for whom oocytes were cryopreserved will eventually not...

متن کاملThe Effects of Progesterone on Oocyte Maturation and Embryo Development
Oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. Progesterone (P4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...
متن کاملWildlife Contraception: Targeting the Oocyte
The USDA’s National Wildlife Research Center (NWRC) has successfully researched and developed a number of chemical and immunologically-based wildlife contraceptives. DiazaconTM interferes with cholesterol metabolism and disrupts steroidogenesis, while nicarbazin (registered as OvoControl-P and OvoControl-G) disrupts the structure of the vitelline membrane of bird eggs. Immunologically-based age...
متن کاملThe oocyte-to-embryo transition.
The oocyte-to-embryo transition refers to the process whereby a fully grown, relatively quiescent oocyte undergoes maturation, fertilization, and is converted into a developmentally active, mitotically dividing embryo, arguably one of the most dramatic transitions in biology. This transition occurs very rapidly in Caenorhabditis elegans, with fertilization of a new oocyte occurring every 23 min...
