For normal fertility

Options

A. Human male ejaculates about 200 to 300 million sperm during a coitus
B. At least 40 percent sperms must have normal shape and size
C. At least 30 percent sperms must show vigorous motility
D. All of the above

Answer

To determine the requirements for normal fertility in human males, we can break down the information provided in the video transcript into a step-by-step analysis.

### Step-by-Step Solution:

1. **Understanding Sperm Count**:
- For normal fertility, a human male should ejaculate approximately **200 to 300 million sperm** during sexual intercourse. This is a crucial factor in determining fertility.

2. **Sperm Morphology**:
- It is important that at least **40% of the sperm** have a normal shape and size. This means that a significant proportion of the sperm must be healthy and capable of fertilizing an egg.

3. **Sperm Motility**:
- Additionally, at least **30% of the sperm** must show vigorous motility. This means that these sperm are not only alive but also capable of swimming effectively to reach and fertilize the egg.

4. **Consequences of Abnormalities**:
- If the percentage of sperm with normal morphology or motility falls below these thresholds, the chances of successful fertilization decrease significantly, which can lead to fertility issues.

5. **Conclusion**:
- Based on the criteria mentioned, the correct option for normal fertility is the one that states the male should ejaculate **200 to 300 million sperm**, with at least **40% having normal morphology** and **30% showing vigorous motility**.

### Final Answer:
The correct option for normal fertility is that a human male should ejaculate **200 to 300 million sperm** during coitus, with at least **40% having normal shape and size** and **30% showing vigorous motility**.
