Freezing 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...

In this paper the acceptability of the posthumous reproduction in Islamic contexts is evaluated and major concerns like ...
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 کاملSocial oocyte freezing
Reproductive aging has become an important social and medical development. the trend to delay childbearing in modern societies to a much less fecund age often confronts women with difficulties to conceive. the aging of the ovary resulting in a decline in the total number of oocytes and in their quality cannot be undone. However, it often engenders unrealistic expectations of what modern fertili...
