Doctor's answer:

1. Cervical mucus examination: It is necessary to check the amount of mucus secretion, viscosity, extensibility, and so on. This examination item is preferably conducted continuously during the menstrual cycle, combined with basal body temperature, to achieve higher accuracy in the results.
2. Post-coital test (PCT): It is mainly used to determine whether sperm is compatible with cervical mucus. Currently, it is one of the main diagnostic methods for cervical infertility.
