Patient: I had a semen test at a tertiary care hospital in Beijing and a secondary care hospital. The density was above 25 million, the viability was basically between 35 and 50%, the viability was between 24 and 36%, and the pH was normal except for once at 7.0. The semen volume was also normal and liquefied. But the main difference is in the deformation rate, the deformation rate of the second-tier hospital is about 25%, but the deformation rate of the third-tier is 99.5. But I carefully read the report card, they tested different sperm count, dimethyl Ben test 20-30, the third-tier test about 300, may I ask if this is related to such a big difference in deformation rate? Is there a problem with the level of testing? Answer: The current state of the malformation rate test is rather complicated, with some using the WHO4 version of the standard and some using the WHO5 version of the standard. In addition, some hospitals check the malformation rate in the dynamic state, so the result is very different from the actual situation. The clinical significance is not significant. The correct one should dye the film and assay the spermatozoa over 200 under static condition, and the result will be more consistent with the actual one.
