Preferred Sample Type
Sample Processing in Laboratory
Patient brings specimen in to BHH. Send to ref lab immediately after collection.Sample Preparation
Centrifuge and aspirate supernatant and freeze at -20 ºCTurnaround Time
Not statedSample Stability
-20 ºCFructose (semen)
General Information
The presence of high levels of fructose is normal in the semen and this sugar comes almost entirely from the seminal vesicles. Obstruction of this accessory gland due to infection or tumour will result in low semen volumes since the seminal vesicles normally produce 70% of the seminal fluid. Normal contributions of the seminal vesicle can be easily tested in a semen sample with a biochemical determination of fructose.
This test would be indicated in cases of hypospermia (low semen volume) or symptomatic infection of the seminal vesicle. If hypospermia presents with azoospermia (lack of sperm in the ejaculate), the patient may suffer from congenital absence of the vas deferens. The concentration of fructose in a semen sample is a quick and inexpensive way to screen for this possibility and to determine if further workup is indicated.
Patient Preparation
None
Notes
The absence of fructose in the semen may indicate that the man has congenital absence of the vas deferens, or has a blockage of the seminal vesicles.
