Shrinkage of the testicles can be caused by aging, decreases in testosterone, infections, or alcohol abuse. Many of these conditions can also cause erectile dysfunction. Keep track of all your symptoms. If you are concerned about these or any other symptoms, describe all your symptoms to your doctor to determine the cause.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Low Testosterone (Low T)
Low testosterone (low-T) can be caused by conditions such as type 2 diabetes, obesity, liver or kidney disease, hormonal disorders, certain infections, and hypogonadism. Signs and symptoms that a person may have low-T include insomnia, increased body fat, weight gain, reduced muscle, infertility, decreased sex drive, depression, and worsening of congestive heart failure or sleep apnea. Low-T can be treated with testosterone therapy in the form of gels, injections, pellets, or skin patches. Side effects of testosterone treatment include acne, anxiety, hair loss, headache, and change in sex drive (libido).
Priapism (Penis Disorder)
Priapism is a penis disorder characterized by a prolonged, unwanted erection of the penis. Medical conditions, trauma, or medications can cause priapism. There are three categories of priapism: ischemic priapisim, non-ischemic priapism, and stuttering priapism. Treatment includes medical intervention, medication, and at times, surgery.
At MedicineNet, we believe it is important to take charge of your health through measures such as a living healthy lifestyle, practicing preventative medicine, following a nutrition plan, and getting regular exercise. Understanding your symptoms and signs and educating yourself about health conditions are also a part of living your healthiest life.
