When it is time for collecting semen, you want to make sure that the products you are using are non-spermicidal. Our Ster-L-Jelly is both non-spermicidal and sterile! Both the 1 oz and 5 oz containers have a handy flip top lid making for easy access to the lube with one hand. The 1 oz comes individually or in boxes of 24, the 5 oz is also available individually or in boxes of 12.
