2. The development of the hymen
According to modern medical research, women's hymen has been formed during fetal development. Generally, when the embryo develops to 3 or 4 months, it will be fully developed and mature at puberty, and its shape is different.

3. Questions about the hymen
In the traditional concept, it is believed that only virgins have hymen, and if there is no hymen, then it is not a virgin (intercourse has already occurred). Obviously not. There are many possible factors for hymen rupture, not only intercourse, and even some women are born without a hymen, so whether the hymen ruptures is not necessarily related to whether it is a virgin.
