Post coital test showing non motile sperms in the cervical smear and Motile sperms from the posterior fornix suggests:
**Core Concept**
The post coital test (PCT) assesses the interaction between sperm and cervical mucus, evaluating fertility. It involves examining a cervical mucus sample for sperm motility after intercourse. **Sperm motility** and **cervical mucus interaction** are crucial for successful fertilization.
**Why the Correct Answer is Right**
Given that non-motile sperms are found in the cervical smear but motile sperms are present in the posterior fornix, this suggests a problem with sperm migration through the cervical mucus, not with sperm motility itself. This pattern is indicative of **cervical factor infertility**, where the cervical mucus may be too thick or have anti-sperm antibodies, preventing sperm from penetrating and migrating upwards.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it doesn't specify the nature of the issue.
**Option B:** Incorrect as it might imply a problem with the sperm themselves, not their interaction with cervical mucus.
**Option C:** Incorrect because it doesn't relate to the specific findings of the post coital test.
**Option D:** Incorrect as it is the correct answer choice that is missing.
**Clinical Pearl / High-Yield Fact**
The post coital test can help differentiate between male and female factors in infertility, with specific patterns suggesting **cervical factor infertility** or **male factor infertility**. Understanding the implications of sperm motility in different parts of the female reproductive tract is crucial for diagnosing and managing infertility.
**Correct Answer:** D. Cervical factor infertility.
