Towards whole sheep ovary cryopreservation q
Cryopreservation of ovarian tissue aims to assist young women who require treatments that may lead to sterility or infertility. Cryopreservation procedures should therefore be as simple and efficient as possible. This study investigates rapid cooling outcomes for whole sheep ovaries. Ovaries were perfused with VS4 via the ovarian artery, and cooled by quenching in liquid nitrogen in less than a...
متن کاملFreezing within 2 h from oocyte retrieval increases the efficiency of human oocyte cryopreservation when using a slow freezing/rapid thawing protocol with high sucrose concentration.
BACKGROUND A number of factors influence the success of oocyte cryopreservation and subsequent ICSI. The aim of the present study is to establish the ideal time, after oocyte retrieval, for human oocyte cryopreservation via slow freezing/rapid thawing protocol with 0.3 M sucrose concentration in cryoprotectant solution (SF/RT 0.3 M). METHODS Retrospective study with 75 patients on the clinica...
متن کاملHuman oocyte cryopreservation: 5-year experience with a sodium-depleted slow freezing method.
A slow freezing/rapid thawing method for the cryopreservation of human oocytes has been employed using a sodium-depleted culture media. In 53 frozen egg-embryo transfer (FEET) cycles, a 60.4% survival rate post-thaw was obtained and a 62.0% fertilization rate following intracytoplasmic sperm injection. Overall pregnancy rates were 26.4% per thaw attempt, 30.4% per patient, and 32.6% per embryo ...
متن کاملTechniques for Ovarian Tissue, Whole Ovary, Oocyte and Embryo Cryopreservation
In recent years, preservation of fertility in women has been of great importance, especially in patients exposed to deleterious conditions on fertility. Thus, cryopreservation of human gametes, embryos and ovarian tissue has become an essential part of assisted reproduction. This approach limits the number of embryos transferred, while supernumerary oocytes and/ or embryos can be used in subseq...
متن کاملProspective randomized comparison of human oocyte cryopreservation with slow-rate freezing or vitrification.
OBJECTIVE To compare cryopreservation of mature human oocytes with slow-rate freezing and vitrification and determine which is most efficient at establishing a pregnancy. DESIGN Prospective randomized. SETTING Academically affiliated, private fertility center. PATIENT(S) Consenting patients with concerns about embryo cryopreservation and more than nine mature oocytes at retrieval were ran...
