Erectile dysfunction  or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis. There are various underlying causes , such as damage to the nervi erigentes which prevents or delays erection, or diabetes as well as cardiovascular disease, which simply decreases blood flow to the tissue in the penis, many of which are medically treatable. The causes of erectile dysfunction may be psychological or physical. Psychological erectile dysfunction can often be helped by almost anything that the patient believes in; there is a very strong placebo effect. Physical damage can be more difficult to treat. One leading physical cause of ED is continual or severe damage taken to the nervi erigentes  . These nerves course beside the prostate arising from the sacral plexus and can be damaged in prostatic and colorectal surgeries. Diseases are also common causes of erectile dysfunctional ; especially in men . Diseases such as cardiovascular disease, multiple sclerosis, kidney failure, vascular disease and spinal cord injury can cause erectile dysfunction.Nolen-Hoeksema, S. (2013). Sexual Dysfunctions. In Abnormal Psychology. McGraw Hill Education.  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.Waldinger M.D., Berenden H.H., Blok B.F., et al. Premature Ejaculation and Serotengeric Anti-depressants - Induced Delayed Ejaculation: The Involvement of the Serotonergic System. Behavioural Brain Res. 1998;92(2): 111-118 For a diagnosis, the patient must have a chronic history of premature ejaculation, poor ejaculatory control, and the problem must cause feelings of dissatisfaction as well as distress  the patient, the partner or both. In men, postorgasmic illness syndrome (POIS) causes severe muscle pain throughout the body and other symptoms immediately following ejaculation. The symptoms last for up to a week. Some doctors speculate that the frequency of POIS "in the population may be greater than has been reported in the academic literature", and that many POIS sufferers are undiagnosed. Dhat syndrome is another condition which occurs in men. It is a culture-bound syndrome which causes anxious and dysphoric mood after sex, but is distinct from the low-mood and concentration problems (acute aphasia) seen in postorgasm illness syndrome .
