If male ejaculate contains insufficient quantity of  spermatozoa or no spermatozoa at all, such a disease would be commonly referred to as “azoospermia”.

Azoospermia can be classified as obstructive (excretory) and non-obstructive (secretory) azoospermia. 

Azoospermia of obstructive type involves obstruction of spermoducts, which is, most commonly, due to disorders in the development of sexual organs, as well as traumas or inflammations caused to various segments of the reproductive system. 

Non-obstructive azoospermia is applied to cases where no spermatozoa are generated in testicles. This disease is due to a variety of anomalies in their development, as well as inflammation of testicles and their appendages caused by infections, radiation, alcoholism, exposure to cold, lack of A and E vitamins, as well as by many other factors.  

As far as obstructive azoospermia is concerned, the PESA and TESA methods are applied for spermatozoa generation purposes.

PESA : needle biopsy of several segments of testicle appendages

ТESA : special male infertility treatment method applicable to cases where, using the subcutaneous testicle biopsy technique, semen is collected with the help of a special syringe

The TESE method is applied to non-obstructive azoospermia conditions. 

TESE  : aspiration (biopsy) of testicle tissue; tissue is used to separate spermatozoa for oocyte fertilization purposes
