The Canterbury Tales: The Wife of Bath's Prologue The Wife of Bath Quotes

This clerk, whan he is oold and may noght do
Of Venus werkes worth his olde sho,
Thanne sit he doun, and writ in his dotage
That wommen kan nat kepe hir mariage
.
(713-716)

With this statement, the Wife implies that a clerk's slander of women may be due to jealousy or curmudgeonly-ness due to impotence in age. If the clerk isn't having sex, maybe he doesn't want anyone else to be having it either. If he discourages marriage, maybe no one will!
