University Reproductive Associates is conducting a pilot study to study the technique of egg freezing. Your participation in this study will provide us with important information to allow us to offer this technology for women wishing to freeze their eggs before cancer treatments. Your participation will include a standard IVF cycle with your eggs being frozen for a brief period of time and then transferred back to you as usual. You will receive a significant reduction in your IVF cycle cost.
Control: Historical Control, Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

In the space of a few decades, oocyte cryopreservation has become established in the world of reproductive biology with the authorization of oocyte vitrification. This ultra-fast manual fr...
Oocyte cryopreservation has been studied for many years without much success in refining a method that has consistent, reliable results in producing viable embryos and clinical pregnancies...
For an efficient "egg banking" system, an equally efficient cryopreservation strategy that ensures the viability of the oocytes is required. Very recently, improved and new methods are yie...
Human oocyte cryopreservation is routinely used for fertility preservation of women who will be exposed to gonadotoxic effect of cancer treatment. After ovarian stimulation, matured oocyte...
Human embryos can be preserved for later transfers by freezing. Traditionally the slow cooling method has been used. About 70% of the embryos remain fully intact after thawing. However, th...
The objective of this study was determination of the changes in the reactive oxygen species (ROS) level, mitochondrial DNA (mtDNA) copy number and enzyme activity and transcription factor A (TFAM) gen...
Previous studies have found low rates of blastocyst development (0-11%) after vitrification of germinal vesicle (GV)-stage equine oocytes. In this study, we systematically evaluated a short (non-equil...
Vitrification of ovarian tissue containing immature oocytes provides an important tool for protecting the endangered species and genetic diversity in aquatic species. Therefore, the main objective was...
Currently, open systems are mainly used for cryopreservation of ovarian tissue, oocytes, and embryos, but there is a potential risk of contamination. This study was performed to assess ovarian tissue ...
SummaryCumulus cells (CCs) play an important role in the regulation of female gamete development, meiotic maturation, oocyte-sperm interaction, capacitation and acrosome reaction. However, their role ...
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
Minute cells produced during development of an OOCYTE as it undergoes MEIOSIS. A polar body contains one of the nuclei derived from the first or second meiotic CELL DIVISION. Polar bodies have practically no CYTOPLASM. They are eventually discarded by the oocyte. (from King & Stansfield, A Dictionary of Genetics, 4th ed)
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
The transformation of a liquid to a glassy solid i.e., without the formation of crystals during the cooling process.
An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.
