There are generally no IVF transfers that take more than ten days to implant, but there may be individual variations. IVF refers to in vitro fertilization-embryo transfer technique, which is an assisted reproductive technology that needs to be operated by a professional physician. Most women will implant 3 to 5 days after the embryo transfer, usually no more than 7 days. However, there may be individual differences, and a very small number of women may be able to implant their embryos more than ten days after embryo transfer. After the embryo transfer, it is necessary to pay attention to appropriate rest, not strenuous exercise and exertion, prohibit sexual intercourse, and continue to follow the doctor’s instructions to give luteal support therapy. Generally, blood or urine hCG (human chorionic gonadotropin) test is performed about 2 weeks after embryo transfer to confirm pregnancy, and ultrasound examination is performed about 4 weeks after transfer to confirm intrauterine pregnancy.
