Anorgasmia: Failure to achieve orgasm (climax) during sexual intercourse. Anorgasmia can result from many causes including stress, anxiety, depression, fatigue, worry, guilt, fear of painful intercourse, fear of pregnancy, the undesirability of a partner, the undesirability of a setting, and the use of alcohol, prescription or illicit drugs. In women, this problem is also referred to as "frigidity," or female orgasmic dysfunction.

"Anorgasmia" is derived from the Greek "an" (without, not), the Greek "orgasmos" (swell) and the Greek and Latin "ia" (a suffix used in the names of ailments). Also known as orgasmic disorder, orgasmic dysfunction, and orgasmic inhibition.
