The mice were irradiated with ultrasound at the implantation site of the somatic embryos, the uterus and embryos were placed in the same ultrasound field for synchronous study, and the pregnant mice and pigs were irradiated with uterus, histologically, electrophysiologically, and cell morphology And work
