Debrief: What This Result Set Supports

This case's numbers all meet the WHO 2021 lower reference limits, and the collection history supports treating those numbers as a valid description of this specimen: abstinence, complete collection, and timing were all within the ranges described. What the case does not support is a fertility conclusion. WHO's reference values are the 5th percentile of a population of male partners who conceived within 12 months, not a fertile/infertile cutoff, and a single result above every limit does not by itself establish fertility any more than a single low result establishes infertility. The same biological variability that can push one specimen's progressive motility close to its limit can produce a materially different result from the same person on a different day.

Method matters on the report as much as the numbers do. Whether concentration and motility were measured manually on a hemocytometer or by an automated computer-assisted semen analysis system changes which validated range and reportable limits apply, and CLIA test complexity for semen analysis is assigned to the specific test system used, not to the specimen type alone; a laboratory-developed or manufacturer-modified method defaults to high complexity, while some FDA-cleared analyzers are categorized as moderate complexity. None of that changes what the sperm are doing under the microscope, but it changes what your laboratory has to validate and document before releasing the number.

Local procedure decides several specifics: the exact standard temperature range for analysis (20 to 27 degrees C for transport is this laboratory's own validated example), the precise vitality-testing trigger percentage, the acceptability criteria for inter-observer morphology agreement, and whether and how a concentrating technique is applied to an azoospermic specimen. Those are laboratory-director decisions documented in a written procedure, not universal numbers to memorize. Release a semen analysis result with its method, its timing, and its collection history attached, because the numbers alone are not a complete result.
