Can doctors know if you lost your virginity?

In general, doctors cannot tell if a person has lost their virginity through a physical examination or any medical tests. The presence of the hymen, a thin membrane that partially covers the opening of the vagina, is not a reliable indicator of virginity as its presence or absence can vary due to factors such as genetics, physical activities, or trauma. Additionally, sexual activity does not necessarily lead to visible changes in the hymen or the reproductive system. Therefore, doctors cannot definitively determine if someone has lost their virginity based on physical examinations alone.
