Can a premarital medical examination for women detect whether she has been pregnant before?
Generally, premarital medical examinations for women cannot determine if they have been pregnant before.

Most premarital examination items do not include tests that directly detect whether a woman is currently pregnant or has ever been pregnant. Routine premarital checkups mainly focus on screening for infectious diseases, assessing risks of genetic disorders, and performing basic physical examinations such as measuring blood pressure, weight, and vision. These tests cannot determine whether someone has been pregnant previously. Furthermore, medical institutions and doctors respect individual privacy and generally do not proactively disclose information regarding a person's reproductive history.
The primary purpose of the premarital examination is to ensure the physical health of both partners and to identify any conditions that might affect marriage or childbearing. Therefore, even though premarital exams cannot determine whether a woman has been pregnant, women should still undergo premarital checkups. If a woman is concerned about whether she is currently pregnant or has other gynecological issues, she should consult a qualified physician and undergo appropriate examinations.
In daily life, it is recommended to maintain a healthy lifestyle, eat a light diet, and exercise regularly to help improve overall physical condition. Before undergoing medical examinations, it is important to follow the doctor's instructions for preparation to avoid affecting the accuracy of the test results.
