Cryopreservation of embryos, oocytes, or ovarian tissues is the main option for female fertility preservation. Oocyte cryopreservation has emerged as especially important: the dramatic increase in the number of infants born from vitrified oocytes indicates that it is becoming one of the most important intervention options. However, oocyte cryopreservation with standard controlled ovarian hypers...

Fertility preservation has gained increased acceptance, and many reproductive medicine centers have established programs for this service. A recent report, which collected data from all Nordic university hospitals that had initiated programs for fertility preservation (N = 14), found that breast cancer is the most common diagnosis among women who underwent procedures aimed at fertility preserva...

Oocyte cryopreservation has great promise for applications in oocyte donation and fertility preservation and for decreasing the number of unused cryopreserved embryos. The Practice Committee has and will continue to review the published medical literature relating to oocyte cryopreservation at regular intervals and is prepared to reconsider its position when evidence warrants.

Background Fertility preservation for female cancer patients prior to cancer therapy has emerged as an essential component of comprehensive patient care. In the US, approximately 6% of women diagnosed with invasive cancer between 2007 and 2011 that were under 45 years old. The incidence of cancers in reproductive age women signifies a need for fertility preservation options and this need is inc...

Cryopreservation has been a technique used in reproductive endocrinology and infertility medicine since the early 1980s. Embryo cryopreservation, specifically, has been widely used in many in vitro fertilization (IVF) programs worldwide. This method has been well studied and is a common strategy employed for storing supernumerary embryos after IVF cycles, among other applications. Oocyte cryopr...

OBJECTIVE To report the first case of fertility preservation in a premenarcheal female by use of controlled ovarian hyperstimulation and oocyte cryopreservation. DESIGN Case report. SETTING Reproductive endocrinology and infertility unit of a tertiary care university-based medical center. PATIENT(S) A 13-year-old premenarcheal female with Tanner stage 3 breast development and Tanner stage...

OBJECTIVE To evaluate the safety and risk of cryopreservation in female fertility preservation. DATA SOURCES The data analyzed in this review were the English articles from 1980 to 2013 from journal databases, primarily PubMed and Google scholar. The criteria used in the literature search show as following: (1) human; embryo; cryopreservation/freezing/vitrification, (2) human; oocyte/immature...
