Task: Answer Verification
Input (English): Question: Is fetal microchimerism involved in the pathogenesis of lichen sclerosus of the vulva?
Answer: Despite the limited number and size of the samples, we conclude that persistent male fetal cells are not involved in the pathogenesis of lichen sclerosus of the vulva, since we consistently could not detect Y-chromosome specific sequences by using two molecular techniques.
Output (English): no
