OBJECTIVE: To use new medical imaging technology to predict the motility pattern of Trichomonas vaginalis within the vagina. DESIGN: Use of IPAN Tracker IP97, a noniterative, competitive linking algorithm. SETTING: University laboratory. PATIENT(S): None. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Visualization of movement pattern of protozoon within the vagina. RESULT(S): The motility pattern of T vaginalis within the vagina is a vertical zigzag configuration that results in a circular whirling. During movement of spermatozoa, its counteraction by T vaginalis could be visualized. CONCLUSION(S): T vaginalis has flagella and is mobile within the vagina; its whirling movement can disrupt normal sperm movement and potentially result in difficulty in fertilization.
