Vaginal fornix

The fornices of the vagina (sing. fornix of the vagina or fornix vaginae) are the superior portions of the vagina, extending into the recesses created by the vaginal portion of cervix. The word "fornix" is Latin for "arch".

Anatomical terminology


There are two named fornices:

  • The posterior fornix is the larger recess, behind the cervix. It is close to the recto-uterine pouch.
  • There are three smaller recesses in front and at the sides:

Sexual stimulation

During sexual intercourse in the missionary position, the tip of the penis reaches the anterior fornix, while in the rear-entry position it reaches the posterior fornix.[1]

The fornices appear to be close to one reported erogenous zone, the cul-de-sac, which is near the posterior fornix.
