According to the 2010 WHO criteria what are the characteristics of normal semen analysis?
💡 Explanation
**Core Concept**
The 2010 WHO criteria provide a standardized framework for evaluating semen quality, encompassing parameters such as semen volume, sperm concentration, total sperm count, progressive motility, and normal morphology. These criteria aim to distinguish between normal and abnormal semen parameters, facilitating the diagnosis and management of male infertility.
**Why the Correct Answer is Right**
According to the 2010 WHO criteria, normal semen analysis is characterized by a semen volume of at least 1.5 mL, a sperm concentration of at least 15 million per mL, a total sperm count of at least 39 million per ejaculate, progressive motility of at least 32%, and normal morphology of at least 4%. The correct answer, option B, meets these criteria, with a semen volume of 1.5 mL, a sperm concentration of 15 million per mL, and a progressive motility of 32%.
**Why Each Wrong Option is Incorrect**
**Option A:** This option exceeds the maximum allowed sperm concentration of 20 million per mL, making it an incorrect choice according to the 2010 WHO criteria.
**Option C:** This option exceeds the maximum allowed normal morphology of 4%, making it an incorrect choice according to the 2010 WHO criteria.
**Option D:** This option has a semen volume that is below the minimum required by the 2010 WHO criteria, making it an incorrect choice.
**Clinical Pearl / High-Yield Fact**
It is essential to note that the 2010 WHO criteria provide a more stringent definition of normal semen parameters compared to previous guidelines. This change aims to improve the accuracy of semen analysis and reduce the risk of misdiagnosis in cases of male infertility.
