Abstract: The present invention provides devices having an elongated member, a slidable indicator slidably engaged with the member and preferably a measuring scale to determine dimensions of female reproductive organs. Preferably, the device is adapted to determine the length of the cervix in the fornix vaginae, which is used in the disclosed methods to predict the risk of preterm labor, the risk of miscarriage, ease or difficulty of inducing labor, and fertility of an individual. Additional embodiments of the device determine dimensions of the fornix vaginae and dilation of the cervix uteri.
