Low sperm count is one of the main causes of fertility issues in couples experiencing difficulty when trying to get pregnant. Azoospermia is the complete absence of sperm in a semen sample, due to a failure in sperm production or a physical obstruction. If an obstruction is causing the sperm problem, it may be treated in some cases with surgical procedures. If a spermanalysis or a sperm test indicates azoospermia, your doctor will likely pursue follow up tests to determine the cause.
It occurs in 5% of infertile men. If this is the case, then one or both of two conditions may be present:
Conditions That Cause Azoospermia
The value of finding even a small number of sperm in the pellet analysis is very significant because:
In cases of azoospermia that is not due to blockage, termed nonobstructive azoospermia, medical treatment can help some men develop ejaculated sperm (i.e.those with reversible conditions such as Kallman syndrome,hyperprolactinemia;varicocele); in most instances however, the only hope for building a biological family is to use sperm retrieved from the testis with assisted reproduction. One of the most difficult aspects of nonobstructive azoospermia is that only 50%-60% of men will have usable testicular sperm.
