Angiogenesis plays a vital role in the process of embryo implantation, as it improves endometrial receptivity and guides embryo implantation, thus creating a favorable environment for subsequent development of the embryo. Hence, a theory of achieving contraception by inhibiting angiogenesis was put forward. Here, we screened the drugs inhibiting angiogenesis using cell scratch wound assay and a 3D biomimetic vascular microfluidic chip, then observed the effect of them on contraception by injecting these drugs into fertilized mice and observing if the embryos were implanted. We preliminarily verify the feasibility of contraception by inhibiting angiogenesis and gives a new direction in the development of contraceptive pills.
