What does spermicidal mean?
Spermicidal is an adjective meaning destructive to sperm. It is used to describe substances, products, or actions that kill sperm or interfere with their ability to fertilize an egg, most often in connection with contraceptive products and laboratory testing. The most familiar application is the phrase “spermicidal lubricant,” describing a lubricant with sperm-killing properties. The word is more technical than the everyday noun spermicide: spermicide names the substance itself, while spermicidal describes its destructive effect. In medical and product-testing contexts, the term is precise and carries no implication of humor or exaggeration. Although it may occur in both British and American English, it is less common in general speech than the related noun.

- Of or relating to a substance or agent that destroys sperm or impairs its ability to fertilize an egg.
"The laboratory tested the spermicidal effect of the lubricant on samples of semen."
"The formulation was rejected after tests showed that it had a strong spermicidal effect."
"Spermicidal lubricants are advertised as reducing the risk of pregnancy during intercourse."
Spermicidal means “sperm-killing”: the word links the biological noun sperm with the same killing suffix found in words such as pesticide and herbicide.
