what effects penis health ??

Various factors can affect penis health — some modifiable and some not. For example:

• Unprotected sex. You can contract a sexually transmitted infection if you have unprotected sex.
• Heart disease and diabetes. Restricted blood flow caused by diabetes and atherosclerosis — hardening of the arteries — can cause erectile dysfunction.
• Certain medications and treatments. Certain medications and treatments can affect your penis health. For example, surgical removal of the prostate gland (radical prostatectomy) and surrounding tissue as treatment for prostate cancer might cause urinary incontinence and erectile dysfunction.
• Smoking. Smoking doubles your risk of erectile dysfunction.
• Hormone levels. Hormone imbalances, such as testosterone deficiency or too much of the hormone prolactin, have been linked to erectile dysfunction.
• Psychological problems. Depression can cause a loss of libido. Likewise, if you experience an erection problem, you might be concerned that it'll happen again — causing anxiety or depression. This can compound the problem and lead to impotence. Trauma — such as child abuse — can lead to pain associated with sex.
• Neurological conditions. Stroke, spinal cord and back injuries, multiple sclerosis and dementia can affect the transfer of nerve impulses from the brain to the penis, causing erectile dysfunction.
• Getting older. Testosterone levels decline normally as you age. This might lead to a decrease in sexual interest, a need for more stimulation to achieve and maintain an erection, a less forceful ejaculation and a need for more time before you can achieve another erection.
• Piercings. A penis piercing can cause skin infections.
• Aggressive or acrobatic sex or masturbation. If your penis is bent suddenly or forcefully while erect, the trauma might cause a penis fracture. Penis fractures are rare.
