Question

Usually at which pH, the human sperms become motile?

• A. 4.5 to 5.0
• B. 6.0 to 6.5
• C. 7.5 to 8.5
• D. 4.0 to 4.5

Hint:

Human sperm are most motile at a slightly alkaline pH of around 6.0 to 6.5.

Answer 1

The Correct Option is B

Step 1: Understanding sperm motility.
Human sperm become motile in an alkaline environment, typically around a pH of 6.0 to 6.5, which is the ideal pH for sperm motility.
Step 2: Analyzing the options.
(A) 4.5 to 5.0: Incorrect. This pH range is too acidic for sperm motility.
(B) 6.0 to 6.5: Correct. This is the optimal pH for sperm motility in humans.
(C) 7.5 to 8.5: Incorrect. This pH range is too alkaline for sperm motility.
(D) 4.0 to 4.5: Incorrect. This is too acidic and would hinder sperm motility.
Step 3: Conclusion.
The correct answer is (B) 6.0 to 6.5, as this is the optimal pH for sperm motility in humans.
