Strict criteria
According to Kruger, normal forms ≥4% are already good: the criteria are especially strict, because it is the “ideal” forms that fertilize. Values <3–4% for conception failures favor ICSI (sperm injection into the egg), where the morphologist manually selects the best cell. The test complements the basic spermogram and does not replace it.
When is it appointed?
- pregnancy planning - basic check of a man;
- infertility of a couple - the first and mandatory analysis;
- control after varicocelectomy and treatment;
- preparation for IVF/ICSI and cryopreservation;
- suspicion of inflammation - culture and Androflor.
Why start with a man
The male factor is involved in half of the cases of infertility, and it is checked in the easiest way: one test instead of months of examining the partner. The WHO 2021 standard defines references; deviations in one sample are not a death sentence (spermatogenesis is cyclical, 72 days), the diagnosis is based on two tests. The clinic provides the correct preanalytical stage - delivery room, immediate analysis, standardized assessment - on which reliability depends more than on the “coolness” of the laboratory.
