Question

Which of the following test is not suggested for ovulation?

• A. \( \text{Endometrial biopsy} \)
• B. \( \text{Spinnbarkeit} \)
• C. \( \text{Karyopyknotic index of exfoliated vaginal epithelium} \)
• D. \( \text{Cervical biopsy} \)

Hint:

\textbf{Gynecology: Ovulation Assessment.} Various methods are employed to determine if ovulation has occurred, ranging from hormonal assays to physical characteristics of cervical mucus and histological examination of the endometrium. Cervical biopsy serves a different diagnostic purpose related to cervical health.

Answer 1

The Correct Option is D

Several tests are used to assess ovulation, either directly or indirectly by evaluating hormonal changes and their effects on reproductive tissues. Let's examine each option: \begin{itemize} \item Endometrial biopsy: This procedure involves taking a small sample of the uterine lining, typically performed in the luteal phase (after ovulation). Histological examination can confirm if ovulation has occurred by assessing the secretory changes in the endometrium induced by progesterone. \item Spinnbarkeit: This is a qualitative assessment of the elasticity and thread-forming ability of cervical mucus. Around the time of ovulation, under the influence of high estrogen levels, cervical mucus becomes thin, clear, and stretchy, exhibiting spinnbarkeit. \item Karyopyknotic index of exfoliated vaginal epithelium: This index measures the percentage of superficial cells in vaginal smears that have pyknotic nuclei (small, dense nuclei). High estrogen levels, as seen around ovulation, lead to an increase in the karyopyknotic index. \item Cervical biopsy: This procedure involves taking a tissue sample from the cervix for histological examination. It is primarily used to screen for or diagnose cervical abnormalities, such as dysplasia or cancer, and is not a routine test for assessing ovulation. \end{itemize} Therefore, cervical biopsy is not a test suggested for ovulation.
