Explanation

To analyze the assertion and reason provided in the question, we will break down each statement and evaluate their validity.

### Step 1: Analyze the Assertion (A)

- Fructose is a sugar that is primarily found in semen, which is produced by the male reproductive system.
- The presence of fructose in the female genital tract typically indicates that sperm has been deposited there, which usually occurs during sexual intercourse.
- Therefore, the assertion is incorrect because the presence of fructose does not specifically indicate pregnancy; it indicates prior sexual intercourse.
