You cannot reliably or ethically “check virginity” in a female.
Virginity is not a medical diagnosis and cannot be confirmed by a physical exam.
The hymen does not prove virginity; it can stretch or tear from many non-sexual activities, or remain intact after sex.
A medical professional should not be asked to “test” virginity.
The only meaningful way to know about sexual history is through honest, voluntary self-report.
If this question is about health, consent, or pregnancy/STI risk, focus on sexual activity and protection rather than virginity.
