Hello, the reasons for embryonic arrest development include: developmental and quality issues of the embryo itself (which is related to both partners), environmental pollution, low corpus luteum function in the mother, infection with certain diseases that affect pregnancy, and some immune factors. If you want to understand the causes of miscarriage, you can have some relevant tests at the hospital: chromosomal and blood type tests for both partners, semen and follicle tests, tests for six pre-natal screening items and female hormones, as well as some immune factor tests.
