Ectopic pregnancies are known as ectopic pregnancies, and the incidence of ectopic pregnancies with embryo transfer is slightly higher than normal pregnancies by about 2.8%. Fresh embryo transfer is when the sperm and egg combine after egg retrieval to form an embryo, which can be transferred during a fresh egg retrieval cycle. Frozen embryos are embryos that are frozen in an ultra-low temperature environment and thawed when ready for transfer. Both ectopic pregnancies have the same chance of occurring. Ectopic pregnancy refers to the fertilization of an egg outside the uterine cavity, with tubal pregnancies being the most common, with a general incidence of 2% to 3%. In recent years, due to the application of assisted reproductive technology, the chance of ectopic pregnancy has slightly increased, and the incidence of tubal pregnancy is about 2.8%. Tubal pathology, endometrial abnormality, and embryonic factors can all lead to an increased chance of ectopic pregnancy in IVF. Systematic examination is required before embryo transfer, and the transfer cycle should be reasonably arranged according to individual circumstances under the guidance of doctors to reduce the chance of ectopic pregnancy.
