Organic personality disorder (OPD) or secondary personality change, is a condition described in the ICD-10 and ICD-11 respectively. It is characterized by a significant personality change featuring abnormal behavior due to an underlying traumatic brain injury or another pathophysiological medical condition affecting the brain. Abnormal behavior can include but is not limited to apathy, paranoia and disinhibition.In the ICD-10, it is described as a mental disorder and not included in the classification group of personality disorders. In the ICD-11, it is described as a syndrome. The condition has not been described in any edition of the Diagnostic and Statistical Manual of Mental Disorders. Signs and symptoms
OPD is associated with a large variety of symptoms, such as deficits in cognitive function, dysfunctional/abnormal behaviour, psychosis, neurosis, higher irritability and altered emotional expression. Those with OPD can experience emotional lability, meaning that their emotional expressions are unstable and fluctuating. In addition, patients may show a reduction in ability of perseverance with goals and they disinhibition, often characterised by inappropriate sexual and antisocial behavior. Those affected can experience cognitive disturbances, suspiciousness and paranoia. Altered language processing in the brain can also occur. Furthermore, patients may show changes in their sexual preference and hyposexuality symptoms. Causes
OPD is associated with "personality change due to general medical condition".
Webbed penis also known as buried or concealed penis is an acquired or congenital condition in which the scrotal skin extends onto the ventral penile shaft. The penile shaft is buried in the scrotum or tethered to the scrotal midline by a fold or web of skin. The urethra and erectile bodies are usually normal. Webbed penis is usually asymptomatic, but the cosmetic appearance is often unacceptable. This condition may be corrected by surgical techniques.In the congenital form, the deformity represents an abnormality of the attachment between the penis and the scrotum; the penis, the urethra, and the remainder of the scrotum typically are normal. Webbed penis may also be acquired (iatrogenic) after circumcision or other penile surgery, resulting from excessive removal of ventral penile skin; the penis can retract into the scrotum, resulting in secondary phimosis (trapped penis). Signs and symptoms
Since the penis does not protrude when a man has this disorder, his ability to pass urine when he is standing or to participate in sexual intercourse will be impaired. Visible signs may include but are not limited to:

Excessive skin and fat around the penis. Tight, scarred preputial orifice. Straining to urinate. Cause
Webbed penis can be caused by various things such as:
Morbid obesity: which is known as excess fat around the genital area and abdomen, which makes the penis appear as though it is hidden. Abnormalities that are there during birth – ligaments that attach the penis to underlying structures may be weaker than it is supposed to be.
