A method operable to more accurately monitor the state and function of the cervix is provided. Embodiments of the present invention relate generally to detection of fluorescence from the female mammalian cervix. More particularly, embodiments of the present invention relate to predicting true term and preterm labor and delivery, characterizing the function and state of the cervix, and for assessing and monitoring the efficacy of treatments for the cervix. Embodiments of the present disclosure use light induced fluorescence (LIF) via a non-invasive optical probe to accurately and quantitatively measure changes in the cervical tissue during pregnancy and labor. As gestational age increases, the LIF decreases. Ideally, cervical collagen should be at a minimum just prior to delivery. The present invention can be used to monitor the state and function of the cervix during pregnancy, as well as efficacy of cervical treatments during pregnancy.
