Anorgasmia (often relate to delayed ejaculation in males) is a form of sexual dysfunction sometimes classified as a psychiatric disorder in which the patient cannot achieve orgasm, even with "adequate" stimulation. However, it can also be caused by medical problems such as diabetic neuropathy, multiple sclerosis, pelvic trauma, hormonal imbalances, total hysterectomy, spinal cord injury and cardiovascular disease. Anorgasmia is far more common in females than in males and is especially rare in younger men.
