**Question:** Beaded feel of fallopian tube on hsg is seen in.

**Core Concept:** Hysterosalpingography (HSG) is an imaging test that involves the injection of a contrast medium into the uterus and fallopian tubes to assess their patency, anatomy, and function. The beaded feel of the fallopian tube on HSG indicates a specific condition.

**Why the Correct Answer is Right:** The correct answer is **Option C: Tubal Factor Infertility (TFI)**. In TFI, the fallopian tubes become narrowed and sometimes obstructed, causing abnormalities in the menstrual cycle and subsequent impaired fertilization. This results in irregular uterine bleeding, pain during sexual intercourse, and difficulty conceiving.

**Why Each Wrong Option is Incorrect:**

A. **Option A: Adenomyosis (AMY):** Adenomyosis is characterized by the ectopic presence of endometrial glands and stroma within the myometrium, leading to symptoms like dysmenorrhea, pelvic pain, and abnormal uterine bleeding. The beaded feel of fallopian tubes is not a feature of adenomyosis.

B. **Option B: Endometriosis (EMT):** Endometriosis refers to the presence of endometrial tissue outside the uterus, typically causing pelvic pain, dysmenorrhea, and infertility. The beaded feel of fallopian tubes is not a feature of endometriosis.

C. **Option C: Tubal Factor Infertility (TFI):** As explained above, TFI results in narrowed and obstructed fallopian tubes, leading to impaired fertilization and infertility. The beaded feel of fallopian tubes is a characteristic feature of TFI.

D. **Option D: Leiomyosarcoma (LMS):** Leiomyosarcoma is a rare malignant tumor of the uterine smooth muscle, causing abnormal uterine bleeding, pelvic pain, and potentially threatening life. The beaded feel of fallopian tubes is not a feature of leiomyosarcoma.

**Clinical Pearl:** Beaded feel of fallopian tubes on HSG is a characteristic feature of Tubal Factor Infertility (TFI). Understanding this finding aids in diagnosing infertility and guiding subsequent management, including fertility treatments and referral to a reproductive endocrinologist or gynecologist for further evaluation.
