Azoospermia (“No Sperm Count”) – Azoospermic Causes, Treatment and Success Stories
Description:Although a low sperm volume is more likely to be due to the incomplete collection of the ejaculate, it may also be due to obstruction of the ejaculatory duct or congenital bilateral absence of the vas deferens CBAVD 12, Nonobstructive azoospermia was defined as moderate to severe testicular atrophy with markedly elevated serum follicle-stimulating hormone greater than 3 times normal , or a testicular biopsy that revealed maturational arrest, severe hypospermatogenesis or the Sertoli-cell-only pattern. The traditional definition of azoospermia is ambiguous, which has ramifications on the diagnostic criteria. In reality, it is a test that requires skill and expertise. Centrifugation time and speed In the literature, there are different recommendations for the speed and time of centrifugation Table 1. All could be obtained commercially Centrifugal force is applied to enable the motile sperms to swim from a less dense seminal fluid into a denser solution.
