Absence of sperm motility is

Options

A. Azoospermia
B. Asthenozoospermia
C. Teratoaspermia
D. Oligozospermia

Answer

**Step-by-Step Solution:**

1. **Understanding Sperm Motility**: Sperm motility refers to the ability of sperm to move efficiently. It is crucial for sperm to swim through the female reproductive tract to reach and fertilize the ovum.

2. **Identifying the Terms**: The question presents several terms related to sperm health:
- **Azoospermia**: This condition is characterized by the absence of sperm in the semen, leading to infertility.
- **Asthenozoospermia**: This condition involves reduced sperm motility, meaning the sperm have decreased movement capability, which affects their ability to fertilize an egg.
- **Teratozoospermia**: This refers to abnormal sperm morphology, where the shape of the sperm is not normal, potentially leading to infertility.
- **Oligozoospermia**: This condition is defined by a low sperm count in the semen, which can also contribute to infertility.

3. **Analyzing the Options**: The question asks for the condition where sperm motility is absent. Among the options:
- Azoospermia has no sperm at all.
- Asthenozoospermia has reduced motility.
- Teratozoospermia focuses on abnormal shapes, not motility.
- Oligozoospermia has low sperm count, but does not specify motility.

4. **Conclusion**: The condition that specifically indicates the absence of sperm motility is **Asthenozoospermia**, as it directly relates to the reduced movement of sperm.

5. **Final Answer**: The correct answer is **Asthenozoospermia**.
