(A) Optical dipping probes of pH (right) and CO2 (left). (B) Insertion of disposable post-cervical AI catheter. (C) Ex-vivo genital tract simulating the estimated location of the AI catheter in the cervix. (D) Detail of “C” showing how the inner cannula of the AI catheter reaches the body of the uterus. (E) Detail in ex-vivo reproductive tract simulating how the pH probe is inserted within the uterus. After having passed through the AI catheter, the probe was pushed up to reaching the body and horns of the uterus. (F) Data recording from the uterus once the stabilization period is over.
