When thusshaped its anterior end lies behind the upper part of thepubic arch; during effort the anterior end is pressed againstthe pubic bones, and thusthe pessary is preventedfrom coming out. Whetherit is thus retained or not,depends upon the near-ness of the perineum tothe pubic arch (Fig. 39).The perineum may be closeto the pubic arch (), or more than twoinches behind it (Fig. 41). If it be close to the pubic arch, then a vaginal pessaryshaped as described will be well retained. If the peri-neum be far from the pubic arch, the pessary will be. Fig. 37.—Hodges pessary.
