Abstract: Azoospermia is a descriptive term referring to ejaculates that lack spermatozoa without implying a specific underlying cause. The traditional definition of azoospermia is ambiguous, which has ramifications on the diagnostic criteria. This issue is further compounded by the apparent overlap between the definitions of oligospermia and azoospermia. The reliable diagnosis of the absence of spermatozoa in a semen sample is an important criterion not only for diagnosing male infertility but also for ascertaining the… Show more

“…Cryptozoospermia is defined by the presence of very small number of live sperm in pellet and distinguishes it from azoospermia. 2 The finding of live sperm may allow ICSI to be performed with ejaculated sperm, thus obviating the need of surgical sperm retrieval. Sperms usable for ICSI can be found in up to 10% of patients with an initially azoospermic semen specimen after an extended analysis of the centrifuged specimen.…”

“…5 The incidence of azoospermia without implying an underlying etiology is 1% amongst men and close to 20% in men seeking fertility treatment. 2,4 Azoospermia is classified as obstructive (reproductive tract obstruction) or non-obstructive (inadequate production of spermatozoa by testis). Mechanical blockage occurring anywhere along the reproductive tract, including the vas deferens, epididymis, and ejaculatory duct can result in obstructive azoospermia.…”

“…Распространённость азооспермии в популяции всех мужчин составляет около 1 %, а среди мужчин, страдающих бесплодием,-10-15 % [2,3]. Биопсия яичка показана всем больным с азооспермией для обнаружения сперматозоидов, так же как и для последующего гистопатоморфологического исследования биоптатов.…”
