First report on fertility after allogeneic uterus transplantation
Uterus transplantation may become the first available treatment for uterine factor infertility, which is due to the absence or malfunction of the uterus. Here we describe for the first time pregnancy after allogeneic uterus transplantation, as a proof of concept of uterine function in a transplanted uterus in a standardized animal model (rat) under immunosuppression.
Viability and function of the cryopreserved whole rat ovary: comparison between slow-freezing and vitrification
Objective To investigate four different protocols for cryopreservation of the whole rat ovary with intact vasculature to evaluate whether differences exist in post-thawing viability of the ovary after either vitrification or slow freezing. Design Experimental study. Setting Obstetrics and gynecology department. Animal(s) Immature Sprague-Dawley female rats. Intervention(s) Ovaries were isolated with the vascular tree intact up to the bifurcation of the abdominal aorta and were subsequently cannulated. The ovaries were flushed with increasing concentrations of the cryoprotectant dimethyl sulfoxide (DMSO) to either 1.5 or 7 M. The ovaries underwent cryopreservation by vitrification or passive…
