Such compositions can increase a rate of endometrial blood flow and improve embryonic implantation potential just by being applied to the endometrium, and thus may be helpful to patients with subfertility or infertility, especially those who have repetitive failures in embryonic implantation. Since the compositions include botulinum toxin which is a substance that has been widely applied to the human body for cosmetic purposes, studies on human toxicity may have a shortened period, and thus the disclosure is very useful in economical and industrial aspects.
