According to the 2010 WHO criteria the characteristics of normal semen analysis are:
💡 Explanation
**Core Concept**
Normal semen analysis is crucial for assessing male fertility and reproductive health. The 2010 World Health Organization (WHO) criteria provide standardized parameters for evaluating semen quality, which includes volume, concentration, motility, and morphology.
**Why the Correct Answer is Right**
According to the 2010 WHO criteria, normal semen analysis requires a semen volume of at least 1.5 mL. This volume is essential for ensuring the presence of a sufficient amount of sperm for fertilization. The WHO criteria also emphasize the importance of semen analysis in evaluating male fertility, particularly in cases of infertility or subfertility. The semen volume is a critical parameter, as it affects the overall quality and quantity of sperm.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect, as the 2010 WHO criteria specify a minimum semen volume of 1.5 mL, not 1 mL.
**Option B:** Incorrect, as there is no specific WHO criterion for semen volume in the range of 0.5-1 mL.
**Option C:** Incorrect, as the WHO criteria do not specify a maximum semen volume, only a minimum.
**Clinical Pearl / High-Yield Fact**
A semen volume of less than 1.5 mL can be indicative of hypogonadism, which requires further investigation and management.
