Differential Diagnosis for Blood from Penis during Sex
Single Most Likely Diagnosis
- Peyronie's disease: This condition is characterized by the formation of fibrous scar tissue inside the penis, leading to curved, painful erections. It can cause bleeding during sex due to the rupture of small blood vessels in the scar tissue.
Other Likely Diagnoses
- Urethritis: Inflammation of the urethra, often caused by infection, can lead to bleeding during sex.
- Prostatitis: Inflammation of the prostate gland can cause bleeding during ejaculation or sex.
- Penile trauma: Injury to the penis, such as a cut or bruise, can cause bleeding during sex.
- Balanitis: Inflammation of the glans penis, often caused by infection or poor hygiene, can lead to bleeding during sex.
Do Not Miss Diagnoses
- Penile cancer: Although rare, penile cancer can cause bleeding during sex and is a potentially life-threatening condition if left untreated.
- Urethral stricture: A narrowing of the urethra, often caused by injury or infection, can lead to bleeding during sex and is a serious condition that requires prompt treatment.
- Bleeding disorder: Conditions such as hemophilia or bleeding disorders can cause excessive bleeding during sex, and it is crucial to identify and manage these conditions to prevent serious complications.
Rare Diagnoses
- Amyloidosis: A rare condition characterized by the deposition of abnormal proteins in various tissues, including the penis, can cause bleeding during sex.
- Sickle cell disease: A genetic disorder that affects hemoglobin production can cause bleeding during sex due to the rupture of small blood vessels in the penis.
- Henoch-Schönlein purpura: A rare condition characterized by inflammation of small blood vessels can cause bleeding during sex, although it is more commonly associated with other symptoms such as rash and joint pain.
