Improvement in cancer treatments has allowed more women to plan a pregnancy once the disease is cured. The effects of chemotherapy on ovaries are well proven but those on the uterus, especially the endometrium and embryo implantation are still unknown. Usage of newer tyrosine kinase inhibitors such as nilotinib has revolutionized the management of leukemias. Although nilotinib has been reported to be safe in pregnancy, further studies are needed to evaluate its effect on the process of embryo implantation, especially in women undergoing in-vitro fertilization. We report a case where successful pregnancy outcome was achieved after stoppage of nilotinib before embryo transfer in a woman who had previous four failed attempts while on nilotinib and no other obvious cause of implantation failure. Despite optimal endometrial thickness and receptivity, the pale appearance of endometrium on hysteroscopy was attributed to be a possible effect of nilotinib and prompted us to withhold it.
