BACKGROUND It has been recommended by the American Society of Clinical Oncology and the American Society of Reproductive Medicine that options to preserve fertility be presented at the outset of treatment for cancer. This recommendation may have arisen, in part, to the increasing survival of patients with cancer and the realization that certain forms of cancer treatment can lead to infertility....

Oocyte cryopreservation in carnivores can significantly improve assisted reproductive technologies in animal breeding and preservation programs for endangered species. However, the cooling process severely affects the integrity and the survival of the oocyte after thawing and may irreversibly compromise its subsequent developmental capability. In the present study, two different methods of oocy...

OBJECTIVE To determine the efficiency of our vitrification technique when applied in young fertile women. DESIGN Clinical research and application. SETTING In vitro fertilization center. PATIENT(S) Twenty-one women were recruited from the navy community with 19 patients finishing the study. INTERVENTION(S) Vitrified oocytes with use of the electron microscopic grid method were warmed 6 ...

OBJECTIVE To document outcomes of oocyte cryopreservation performed as a routine procedure in an IVF program. DESIGN Describing the rate of oocyte survival, embryo transfer (ET), implantation, and live births of IVF-intracytoplasmic sperm injection performed on thawed oocytes. SETTING Reproductive medicine center in Italy. PATIENT(S) Women (n = 696) who failed to conceive after IVF-intrac...

current protocols for cancer treatment could lead to the failure of ovarian function and subsequent infertility in women. therefore, utilizing ways to preserve fertility in these individuals seem to be essential. in this review, the full-text of articles which were accessible and had been published during 1976 to 2009 about different methods of female fertility preservation were collected and s...

Oocyte cryopreservation is a promising technology that could benefit women undergoing assisted reproduction. Most studies examining the effects of cryopreservation on fertilization and developmental competence have been done using metaphase II-stage oocytes, while fewer studies have focused on freezing oocytes at the germinal vesicle (GV) stage, followed by in vitro maturation. Herein, we exami...
