Primary hypogonadism - male
Testicular failure occurs when the testicles cannot produce sperm or male hormones.
Testicular failure is uncommon. Causes include:
The following can increase the risk of testicular failure:
Symptoms may include:
Men may also notice they do not need to shave as often.
A physical exam may show:
Other tests may show low bone mineral density and fractures. Blood tests may show a low level of testosterone and high levels of prolactin, FSH, and LH.
Your doctor may also order a semen analysis to examine the number of healthy sperm you are producing.
Sometimes, an ultrasound of the testes will be ordered.
Testicular failure and low testosterone level may be hard to diagnose in older men because testosterone levels normally decrease slowly with age.
Male hormone supplements may treat some forms of testicular failure. Men who take testosterone replacement therapy need to be carefully monitored by a doctor. Testosterone may cause the following:
Avoiding the medicine or activity that is causing the problem may bring testicle function back to normal.
Many forms of testicular failure cannot be reversed. Hormone replacement therapy can help reverse symptoms, although it may not restore fertility.
Testicular failure that begins before puberty will stop normal body growth. It can prevent adult male characteristics (such as deep voice and beard) from developing. This can be treated with testosterone therapy.
Call for an appointment with your health care provider if you have symptoms of testicular failure.
Avoid higher-risk activities if possible.
