## **Core Concept**
The question assesses the interpretation of semen analysis results in the context of male infertility. Semen analysis is a critical diagnostic tool for evaluating male fertility, involving parameters such as sperm count, pH, volume, agglutination, morphology, and motility. Abnormal results can indicate specific issues related to sperm production, transport, or ejaculation.

## **Why the Correct Answer is Right**
The correct answer, **Asthenozoospermia**, is characterized by reduced sperm motility. Given that the semen analysis shows 60% motile sperms, this seems initially within normal limits. However, considering other parameters: sperm count of 15 million/ml (which is slightly low but can be considered borderline), pH of 7.5 (slightly low but within normal range), volume of 2 ml (low, as normal is typically >1.5 ml but often around 3-5 ml), and normal morphology and no agglutination, the focus shifts to the motility in relation to other factors. The provided motility and morphology seem within or near normal limits, but issues like low volume might hint at an obstruction or issue with seminal vesicle contribution.

## **Why Each Wrong Option is Incorrect**
- **Option A: Oligozoospermia** refers to low sperm count ( 40% abnormal forms). Here, 60% of sperms have normal morphology, making this option incorrect.
- **Option C: Azoospermia** refers to the absence of sperm in the ejaculate, which does not match the given sperm count of 15 million/ml.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that normal semen analysis parameters according to WHO (2010) include: sperm count ≥ 15 million/ml, total motility ≥ 40%, progressive motility ≥ 32%, normal morphology ≥ 4% (strict criteria), pH 7.2-8.0, and volume ≥ 1.5 ml. Semen analysis results guide further management, including potential treatments for infertility.

## **Correct Answer:** D. Asthenozoospermia.
