Vascular disease is common in individuals who smoke or have diabetes, peripheral vascular disease, or hypertension. Any time blood flow to the penis is impaired, ED can occur. Drugs are also a cause of erectile dysfunction. Individuals who take drugs that lower blood pressure, antipsychotics, antidepressants, sedatives, narcotics, antacids, or alcohol can have problems with sexual function and loss of libido.Hormone deficiency is a relatively rare cause of erectile dysfunction. In individuals with testicular failure, as in Klinefelter syndrome, or those who have had radiation therapy, chemotherapy, or childhood exposure to the mumps virus, the testes may fail to produce testosterone. Other hormonal causes of erectile failure include brain tumors, hyperthyroidism, hypothyroidism, or adrenal gland disorders. Orgasm disorders
Anorgasmia
Anorgasmia is classified as persistent delays or absence of orgasm following a normal sexual excitement phase in at least 75% of sexual encounters. : 368  The disorder can have physical, psychological, or pharmacological origins. SSRI antidepressants are a common pharmaceutical culprit, as they can delay orgasm or eliminate it entirely. A common physiological cause of anorgasmia is menopause; one in three women report problems obtaining an orgasm during sexual stimulation following menopause. Premature ejaculation
Premature ejaculation is when ejaculation occurs before the partner achieves orgasm, or a mutually satisfactory length of time has passed during intercourse. There is no correct length of time for intercourse to last, but generally, premature ejaculation is thought to occur when ejaculation occurs in under two minutes from the time of the insertion of the penis.
