The Science of the Test Described in Ketubbot 10b

To: Ovum Committee

Subject: About Ketubot 10 b and medicine

Dear Mordechai Halperin

I read about the virginity test in ketubot 10b and wanted to know the emperic scientific plausibility of this working in reality

Firsty some women dont have a hymen when born therefore can get wrongly convicted – is this not so ?

Also hymen can break due to injuries prior to test therefore false positive result (if test works in a scientific sence rather that some sort of miracle providence)

Also cannot alcohol penetrate the inside vulva/delicate permeable internal walls of vagina and produce increased blood levels ?

What are your insights and views on this subject from a scientific perspective ?

Thanks for your help and insights on the subject in advance
