The target of any cryopreservation procedure should be to ensure high survival rates of
living cells after thawing. Two important parameters determine the success of any …

Objective To evaluate whether is possible to vitrify oocytes in an aseptic (hermetically
closed) fashion and maintain clinical results comparable with those of fresh oocytes. Design …

Background Oocyte cryopreservation is a technique with considerable potential in
reproductive medicine, including fertility preservation, as a way of delaying childbearing and …

Enthusiasm for oocyte cryopreservation has been limited by poor pregnancy rates per

reproduction treatment that leads to an increased cumulative outcome while decreasing …

OBJECTIVE: To evaluate obstetric outcomes with oocyte vitrification after ovarian stimulation
(OS) and in vitro maturation (IVM) of immature oocytes. DESIGN: A prospective trial from …

INTRODUCTION Since the first live birth from oocyte cryopreservation three decades ago,
oocyte cryopreservation has become an important component of ART. Cryopreservation …
