Introduction
Under normal circumstances, blastocyst transfer refers to embryo transfer. On day 9 after embryo transfer, the reference value for progesterone should be between 25 ng/mL and 103 nmol/L to be considered normal, although specific values may vary from person to person. Embryo transfer refers to transferring early embryos collected from a female animal's body, or embryos obtained through in vitro fertilization and other methods.
In general, blastocyst transfer refers to embryo transfer. On the 9th day after embryo transfer, the reference range for progesterone should normally be between 25 ng/ml and 103 nmol/L, although specific values may vary among individuals. The detailed analysis is as follows:
Embryo transfer is a technique that involves transferring early embryos from a female animal's body, or embryos obtained through in vitro fertilization or other methods, into another female of the same species with a similar physiological state, allowing the embryo to continue developing into a new individual. On the 9th day after embryo transfer, the normal reference range for progesterone should be between 25 ng/ml and 103 nmol/L. If the progesterone level on the 9th day is below 25 ng/ml, there may be an increased risk of miscarriage. In such cases, patients are advised to follow medical instructions and promptly supplement medications such as progesterone capsules or dydrogesterone tablets to avoid negatively affecting the success rate of the transfer. If the progesterone level exceeds 103 nmol/L on the 9th day, there could be an increased risk of fetal malformations. In severe cases, patients may consider surgical intervention under a doctor’s guidance.
If patients experience any discomfort, they should seek timely medical attention at a hospital to prevent delays in diagnosis and treatment.
