Abstract
Although efficient nonsurgical transfer of embryos in mice would provide many advantages over a surgical method, the low success rate of nonsurgical transfer has hampered its acceptance and use. Here, a plastic catheter was used to mimic embryo transfer process and then the transfer efficiency was evaluated by intrauterine trypan blue dye dispersion. Also 3.5-day blastocysts from natural pregnant mice were transferred through cervix into uterine horns. The results show that 70.9% of CD-1 mouse 3.5-day blastocysts transferred into unilateral uterine horns of pseudopregnant 2.5-day recipients can be developed to live newborns, and an efficient mouse nonsurgical embryo transfer technique was established. The technique was simple, rapid, inexpensive, unlikely to get contaminated, ethical and do not need specialized apparatus, and can completely replace surgical embryo transfer techniques. Moreover, the mouse nonsurgical embryo transfer technique provides a research model for human and other large animal embryo transfer.
