Thesuccess and failure of IVF can be comprehensively judged by the following signs:
1. Sign of success
nEarly pregnancy signals
·HCG positive: Blood test 14 days after transplantation HCG≥25mIU/L, indicating embryo implantation.
· Confirmation of gestational sac: 28 days after transplantation, an intrauterine gestational sac can be seen on ultrasound, indicating a successful clinical pregnancy.
· Fetal heartbeat and embryo: At 6-7 weeks of pregnancy, a fetal heartbeat can be detected through ultrasound, confirming the survival of the embryo.
·Hormonal stability: Progesterone and estrogen levels continue to rise, supporting embryonic development.
· Hormonal stability: Levels of progesterone and estrogen continue to rise, supporting embryonic development.
· No abnormal bleeding or abdominal pain: Mild discomfort is normal, but there should be no persistent abdominal pain or excessive bleeding.
·Live birth delivery: The final success criterion is the 28-week pregnancy and the newborn is healthy.
· Live birth: The final success criterion is when the pregnancy reaches 28 weeks, and the newborn is healthy and alive.

·Menstruation: Menstruation occurs in the normal cycle after transplantation, indicating that you are not pregnant.
· Menstrual cycle: If menstruation occurs during the transplant period, it indicates that pregnancy has not occurred.
· Abdominal pain with bleeding: Sudden severe abdominal pain or continuous bleeding (not in the form of spotting) may indicate biochemical pregnancy or ectopic pregnancy.
·HCG fell instead of rising: HCG<25mIU/L or failed to double 14 days after transplantation, indicating abnormal development of the embryo.
· HCG levels fall instead of rising: After 14 days post-transplantation, if HCG levels are less than 25 mIU/L or there is no doubling of levels, it indicates abnormal embryonic development.
· Empty gestational sac: Ultrasound examination shows that there is no yolk sac or embryonic tissue present in the gestational sac. This condition is referred to as “empty gestational sac pregnancy”.
·Avoid over-interpreting symptoms: Mild abdominal distension, tiredness, etc. may be related to hormone use and are non-specific manifestations.
· Avoid over-interpreting symptoms: Mild abdominal distension, fatigue, etc., may be related to hormonal changes, and are not necessarily indicative of anything serious.
· Scientific review: Strictly follow the doctor’s instructions regarding HCG monitoring and ultrasound examinations. Do not rely solely on subjective feelings for judgment.
· Handling after failure: If there are multiple failures, it is necessary to investigate factors such as embryo quality, endometrial receptivity, and immune conditions.
