Task: Answer Verification
Input (English): Question: Does early cleavage predict treatment outcome following the use of GnRH antagonists in women older than 35?
Answer: In women older than 35 years, the early-cleavage rate of zygotes is significantly lower in the GnRH antagonist group than the agonist group. Early-cleavage status of zygotes is not a reliable predictor for embryo implantation in patients receiving the GnRH antagonist protocol.
Output (English): no
