Example Sentences

The perforate condition recorded in Table 1 may represent any of several stages in oestrus or pregnancy, but is regarded as a crude index of rate of breeding, since voles in the anoestrus stage lack the vaginal orifice.

From Project Gutenberg

Anoestrus females are imperforate, and a vaginal orifice is present only during an active oestral cycle or in pregnancy.
