The Use of Vaginal Lubricants and Ultrasound Gels Can have Deleterious Effects on Sperm Function.

Context: Some vaginal lubricants and ultrasound gels are known to be detrimental to sperm function and therefore could negatively affect fertility.

Aims: The aim of the current study was to develop a sperm motility index (SMI) to test the sperm toxicity of ultrasound gels and vaginal lubricants used in reproductive medicine.

Settings And Design: Two ultrasound gels (Aquasonic and Kefus) and five vaginal lubricants (Vaginesil™, Velastisa, K-Y Jelly, Control, and Durex) were studied.
