Types of azoospermia

There are two types of azoospermia, considering where the problem takes place. Therefore, we distinguish between secretory azoospermia (a.k.a. non-obstructive azoospermia) and obstructive azoospermia.

Secretory azoospermia

The secretory azoospermia or non-obstructive is the most serious type, as the testis do not produce spermatozoa. The causes can be either hormonal or testicular.

Obstructive azoospermia

The other type, obstructive azoospermia, refers to an effective production (the testicles of the patient do produce sperm), that is not ejaculated because of a problem with delivery; the ducts that transport sperm to the urethra are not working properly.

    Dear Doctor,

    I am 30 years old man, got married two years before, since then we were trying to have a baby, but later on my Semen report it was said “Azoospermia”.

    My Question is, how can I identify if my azoospermia is a Secretory or Obstructive one.

    Which test should I perform to know the type of Azoospermia?

    Please suggest.

      Dear Balasurbamanian

      First, with a testicular palpation, the doctor can detect if there is sperm production in the testicles. Then, an analysis of the hormones values can help to determine if there’s a problem in the sperm production.

      Finally, if these 2 tests reveal that you can produce sperm, you can perform a testicular biopsy or a sperm aspiration to look for sperm and then, use them in an assisted reproduction technique to have a baby.

      For more information about how to diagnose azoospermia, you can read this page: http://www.azoospermia.info/diagnosis-of-azoospermia/

      I hope I could help you,

      Dear Mahesh,

      When sperm is found morphologically abnormal, the condition is known as “teratospermia” or “teratozoospermia”. You can find detailed info about this sperm pathology here: teratozoospermia.net

      I hope this helps,
