Claim Text:
1. A system for recovering one or more blastocysts from the uterus of a human, comprising: a uterine lavage device which is configured to be trans-vaginally inserted into the cervical canal; a controller programmed to cyclically deliver fluid through the lavage device to the uterus in at least two cycles, wherein the controller is programmed to deliver, in a first cycle of the at least two cycles, a first amount of fluid to form a first puddle encompassing one or more blastocysts and to apply a vacuum to the device to aspirate fluid and entrained blastocysts within the first puddle from the uterus, and, in a second cycle of the at least two cycles, to deliver a larger amount of fluid into the uterus to form a second, larger puddle and to apply a vacuum to the device to aspirate fluid from the uterus; and further comprising a pharmaceutically acceptable container comprising a GnRH antagonist in an amount sufficient to cause desynchronization of the endometrium to reduce a chance that any embryos remaining in the uterus will form a viable pregnancy.
