Instructions

• Separate specimens must be submitted when multiple tests are ordered (a separate sample is needed for Semen Analysis/Fertility testing).
• If specimen is to be collected at home, instruct the patient to freeze immediately after collection.

Specimen Collection Criteria

Collect: Semen in a sterile container. (Minimum: 0.3 mL)

Critical frozen. Specimen must be frozen within two hours of collection.

Physician Office/Draw Specimen Preparation

Critical frozen. Maintain specimen frozen (-20°C/-4°F or below) prior to transport.

Preparation for Courier Transport

Transport: Semen in a sterile container, frozen (-20°C/-4°F or below). (Minimum: 0.3 mL)

Rejection Criteria

• Specimens that are not frozen.
• Specimens not collected and processed as indicated.

In-Lab Processing

Critical frozen. Specimen must be frozen within two hours of collection.

Transport: Semen in a sterile container, frozen (-20°C/-4°F or below). (Minimum: 0.3 mL)

Storage

Specimen Stability for Testing:

Room Temperature (20-26°C or 68-78.8°F): Unacceptable
Refrigerated (2-8°C or 36-46°F): Unacceptable
Frozen (-20°C/-4°F or below): 2 years

Specimen Storage in Department Prior to Disposal:

Specimen retention time is determined by the policy of the reference laboratory. Contact the Send Outs Laboratory with any questions.

Laboratory

Sent to ARUP Laboratories, Salt Lake City, UT.

Performed

Monday.
Results available in 2-9 days.

Reference Range

91-520 mg/dL.

Test Methodology

Quantitative Spectrophotometry.

Interpretation

The seminal vesicles produce fructose. Fructose is released into the semen during ejaculation. Fructose is the energy source for sperm motility. Semen specimens containing no sperm (azoospermia) and no fructose may indicate the absence of seminal vesicles, absence of the vas deferens in the area of the seminal vesicles, or an obstruction of the seminal vesicles.

Clinical Utility

Semen fructose assay may be useful for patients with azoospermia and low volume ejaculates to establish the origin of the azoospermia.
