Azoospermia is the absence of spermatozoa in the ejaculate. This seminal condition can be caused by an alteration in spermatogenesis (sperm production process) or by an obstruction in the vas deferens that prevents the exit of spermatozoa in the ejaculate. Depending on the cause, azoospermia can be secretory or obstructive, respectively.
There are different reasons why a male may have azoospermia. One of the possible causes is pretesticular factors, which would cause secretory azoospermia. Some of these factors are hypogonadotropic hypogonadism, hyperprolactinemia and androgen desensitization syndrome.
