KY jelly is a water based, stable, odorless, non-greasy and non-staining lubricant. It spreads evenly and is used by doctors and nurses to lubricate rubber products, rectal thermometers, rectal and vaginal nozzles for infants and adults. It is also a personal lubricant used during intimacy. KY jelly is a topical emollient, and has no added color or perfume.

KY jelly vs Lidocaine Jelly
Both lidocaine jelly and K-Y jelly are used to lubricate tracheal tubes during tracheal intubation for general anesthesia. In a study, it was found that adverse effects such as postoperative sore throat, hoarseness, and cough after this procedure may be lesser with KY jelly than lidocaine jelly.
Both of them are used in standard urogynecologic exam. The use depends on the preference of the operator. The water based lubricant or 2% lidocaine gel is used to ease the passage of the device into the urethra to minimize discomfort, and pain.
There are conflicting reports as regards to the advantage of lidocaine jelly over KY gel in reducing pain during urethral catheterization for bladder dysfunction.
