To confirm Obstructive Ampulla
Various glands contribute to specific components of seminal plasma; Prostate – zinc; Seminal vesicle – fructose; Epididymis – neutral a-glucosidase (NAG).
Depending on semen volume, our semen chemistry test for zinc, pH and fructose will confirm Obstructive azoospermia at the ampulla.
Obstructive azoospermia below epididymis may be confirmed if the difference in neutral a- glucosidase activity in the post vasectomy ejaculate between 30- and 90-minute time points during incubation of the assay is lower than each respective value.
