Diagnosing Testicular Failure
Making a diagnosis of testicular failure can be done through a testicular exam as well as through blood tests. Blood testing is done to evaluate the levels of testosterone and gonadotropins (FSH and LH) in a man’s system. Abnormal levels of these hormones will suggest testicular failure.
During a physical exam, your doctor will look for signs of testicular atrophy (shrinkage) and tumors (which can indicate testicular cancer). In men where the condition is present at birth, a lack of clearly defined genitals, resulting in a sexually ambiguous child, is indication of congenital testicular failure.
Sperm Production Issues
Testicular failure can cause the following problems with producing sperm:
Sertoli Cell-Only Syndrome: This condition refers to men whose seminiferous tubules are lined with sertoli cells but lack the cells that help sperm cells divide. As a result, a man is thought to have azoospermia.
Maturation Arrest: While sperm production starts off normally, at some point during its development, maturation completely stops. This causes sperm in the ejaculate to not be fully developed.
Hypospermatogeneses: This occurs when too few sperm are produced effectively causing little to no sperm being present in a man’s ejaculate.
Treating Testicular Failure
Men whose fertility problems stem from hormonal imbalances can be treated through testosterone replacement therapy. However, if the hormonal imbalance is found to be caused by recreational or prescribed drug use, it is likely that testicular function can be recovered if these medications are cut out or altered.
Likewise, if a particular action, such as motorbike riding, is found to be impairing testicular function, you may be required to stop this particular activity.
Unfortunately, though, many times testicular failure cannot be adequately treated in order to restore function. Men who are found to have sertoli cell-only syndrome, maturation arrest or hypospermatogeneses will likely require the use of surgical sperm retrieval methods to recover viable sperm. These sperm can then be used with ICSI and IVF to produce a pregnancy.
