Modifying cryopreservation protocols may be seen as a way to simplify cryobanking procedure and increase satisfying outcomes. The aim of the study was to evaluate the influence of slow cooling protocol and vitrification on IVF outcomes using embryos preserved in the 5th or 6th day after oocyte retrieval. The study compared 2 groups of human embryos underwent slow cooling protocol (n=189) and vi...
BACKGROUND Successful cryopreservation of oocytes and embryos is essential not only to maximize the safety and efficacy of ovarian stimulation cycles in an IVF treatment, but also to enable fertility preservation. Two cryopreservation methods are routinely used: slow-freezing or vitrification. Slow-freezing allows for freezing to occur at a sufficiently slow rate to permit adequate cellular deh...
Despite the initial reactions of disapproval, more and more fertility clinics are now offering oocyte cryopreservation to healthy women in order to extend their reproductive options. However, so-called social freezing is not placed on an equal footing with 'regular' IVF treatments where public funding is concerned. In those countries or states where IVF patients receive a number of free cycles,...
Semen cryopreservation and sperm freezing has a long history of over 65 years. However, embryo freezing and oocyte cryopreservation in human infertility has a shorter history up to 40 years. Embryo and oocyte freezing had a tremendous progress and development in past four decades so it improved from slow freezing procedure with less than 10% survival rate at beginning to vitrification procedure...
