Hello Azoospermia is the medical condition of a male not having any measurable level of sperm in his semen. It is associated with very low levels of fertility or even sterility, but many forms are amenable to medical treatment.  Azoospermia can be classified into three major types as listed. 1...Pretesticular azospermia is characterized by inadequate stimulation of otherwise normal testicles and genital tract. Typically, follicle-stimulating hormone (FSH) levels are low (hypogonadotropic) commensurate with inadequate stimulation of the testes to produce sperm. Examples include hypopituitarism (for various causes), hyperprolactinemia, and exogenous FSH suppression by testosterone. 2  testicular azospermia.In this situation the testes are abnormal, atrophic, or absent, and sperm production severely disturbed to absent. FSH levels tend to be elevated (hypergonadotropic) as the feedback loop is interrupted. The condition is seen in 49-93% of men with azoospermia 3...In posttesticular azoospermia sperm are produced but not ejaculated, a condition that affects 7-51% of azoospermic men. The main cause is a physical obstruction (obstructive azoospermia) of the posttesticular genital tracts. in these conditions sperm are produced but not expelled. Pre- and post-testicular azoospermia a frequently correctible, while testicular azoospermia is usually permanent. A major advancement in recent years has been the introduction of IVF with ICSI which allows successful fertilization even with immature sperm or sperm obtained directly from testicular tissue. IVF-ICSI allows for pregnancy in couples where the man has irreversible testicular azoospermia as long as it is possible to recover sperm material from the testes. Don t loose hope and consult a urologist for proper evaluation of your condition and ultimately some way can be found for you to attain fatherhood. Best of luck. Thanks
