Hymenaeus () or Hymen () was the god of weddings, marriage, and the bridal hymen. It is most commonly caused by an imperforate hymen or a transverse vaginal septum. Other vaginal anomalies can have similar symptoms to an imperforate hymen. For these reasons, virginity cannot be definitively determined by examining the hymen. The outer vaginal opening is normally partly covered by a membrane called the hymen. However, virgins were significantly more likely to have injuries to the hymen than non-virgins. Hymenotomy is the surgical perforation of an imperforate hymen. Use of a tampon could stretch or break the hymen. The introitus is sometimes partly covered by a membrane called the hymen. Mucometrocolpos is the accumulation of mucous secretions behind an imperforate hymen. Correction of an imperforate hymen may be delayed until puberty. A torn hymen may be surgically restored in a procedure called hymenorrhaphy. The effects of intercourse and childbirth on the hymen are variable. During puberty, estrogen causes the hymen to become very elastic and fimbriated. She was examined by ten matrons and two midwives who found her hymen intact.
