Fertigo Medical is developing a device designed to increase the success rates of in vitro fertilization (IVF). The device monitors the uterus in order to predict the optimal timing for receptivity to the implanted embryo. Fertigo Medical invented a device and method to discern the endometrium dating. Special image acquisition and other parameters, combined with sophisticated image processing, has been pre-clinically proven to provide as good an estimate of the uterus status as do the traditional methods (e.g., histology, hormone level, estrus).
