Patient's question:
Hello doctor, one of my friends recently got pregnant but ended up not keeping the child. Could you please tell me how long after a miscarriage can one try to get pregnant again?Doctor's answer:
The main reasons for embryonic arrest are several aspects: First is reproductive endocrine issues, as early embryonic development requires three important hormone levels: estrogen, progesterone, and human chorionic gonadotropin (hCG). If the mother's endogenous hormone levels are insufficient to meet the embryo's needs, it can lead to embryonic arrest. Second is immune factors; if the body has certain antibodies, they can resist embryonic development. Third is reproductive tract infections. After the mother becomes infected, pathogens can enter the placenta through the bloodstream, causing damage to the chorion and capillary endothelium, disrupting the placental barrier, and allowing pathogens to enter the fetus, leading to miscarriage, embryonic arrest, and fetal malformations. In recent years, many studies have shown that mycoplasma infection is associated with embryonic arrest. Women with embryonic arrest have a significantly higher positive rate of mycoplasma infection in cervical secretions compared to normal women, with a highly significant difference. Fourth is uterine issues; both the internal environment of the uterus and the overall uterine environment can affect the embryo. The internal environment refers to the endometrium; if it is too thin or too thick, it can affect implantation. Alternatively, uterine malformations can also prevent development. Fifth is chromosomal issues. Sixth are environmental factors, such as the mother being exposed to harmful substances, radiation, or excessive electromagnetic radiation, taking certain medications, smoking or excessive alcohol consumption, viral infections, or having certain chronic diseases.
