After a woman has had a failed IVF blastocyst transfer, she can have another one in about 6 months. Having an IVF transfer can be harmful to a woman’s body, and certain hormones need to be given to promote ovulation and help the embryos to grow and develop in their beds. The ovarian function and the endometrium need some time to recover after the failed transfer. It takes 6 months for the cycle to be adjusted so that the ovaries can secrete hormones normally to the endometrium, so that the endometrium can grow and shed in a cyclical manner. The failure rate of IVF embryo transfer is around 60%. There are many reasons for the failure, which may be related to the quality of the fertilized egg, the endometrial environment and the health condition of the woman.
