Measurement of intrauterine pressure. Two internal probes connected to pressure transducers were positioned into the lumen cavity near the fundus (for signal acquisition and analysis) and past the internal os (for determination and analysis of sphincter-like action of the internal os).

(A), In vitro culture of viable predecidual cells collected from the cul-de-sac of patients with endometriosis. (B), Epithelial cells collected from the cul-de-sac of patients with endometriosis and cultured in a plated with matrigel. Cell-to-cell adhesion and presence on top of the matrigel bed are visible, indicating viable cells.
