Or anorgasmia. Failure of a male or female to achieve an orgasm (climax) during sexual intercourse. Anorgasmia is characterized by psychologists as a "psychosexual dysfunction," a sexual maladjustment that is psychological or emotional in origin. Anorgasmia can result from a variety of problems, 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 use of alcohol or 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).
