Half a year after a mid-pregnancy miscarriage, thawing transfer is possible after regular menstruation. Thawing transfer is a method of in vitro fertilization-embryo transfer technique, and a suitable endometrial environment is needed before thawing transfer of frozen embryos. It takes some time for the endometrium to recover after a mid-pregnancy abortion, so the frozen embryo can be thawed and transferred half a year after the abortion, with regular menstruation and ultrasound examination of the endometrium recovering well and suitable for embryo transfer. When the frozen embryos are thawed and transferred, it is necessary to pay attention to appropriate rest, not to carry out strenuous exercise and heavy physical labor, appropriate increase in diet and nutrition, and continue to give luteal support therapy as prescribed by the doctor. The pregnancy is usually confirmed by blood or pregnancy test at about 2 weeks after the transfer. Ultrasonography is performed 4 to 5 weeks after transplantation to confirm normal intrauterine pregnancy.
