Historical information

Part of the collection of Dr Frank Forster. The philosophy of this object was to keep the uterus dilated. It was commonly believed at this time that the cervix was the cause of dysmenorrhoea.

The stem pessary was an object used to rectify uterine displacements - either anteversion or retroversion. The device consisted of a stem which is introduced into the uterus, the stem was then attached to an ovoid flange or ball, on which the cervix uteri then rested. Connected to this flange was an external part or wire frame, which in turn was attached at one extremity to a flat tubular portion, passing into the vagina. This was then fixed to the intrauterine portion. The wire frame was then made to press on to the pubis, so that the pessary could be kept in position in utero.
