The effect of ultrasound coupling gels on sperm motility in vitro

Several of the most commonly used ultrasound coupling gels were found to adversely affect sperm motility. These gels should not be used in patients undergoing insemination immediately after a transvaginal pelvic ultrasonographic examination. Instead, we recommend the use of Proception Sperm Nutrient Douche, Nutrient Mixture F-10 (HAM), or nonlubrication of the condom-covered transducer.
