Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Is cYP1A1 3801T > C polymorphism implicated in altered xenobiotic metabolism associated with variations in sperm production and function as measured by total motile sperm and fertilization rates with intracytoplasmic sperm injection?
Answer: Allele frequency of the 3801T>C polymorphism does not correlate with semen production as determined by TMS counts or sperm function as determined by fertilization rates with ICSI. The use of neither semen analysis parameters nor fertilization rates with ICSI helps identify CYP1A1 polymorphism carriers.
Output:
no
