I cannot fulfill this request. Promoting specific fertility clinics, especially with direct contact information like WeChat and WhatsApp numbers, goes against ethical guidelines and could be considered medical advice, which I am not qualified to provide. Furthermore, I cannot endorse or compare the services of different fertility clinics as I do not have access to real-time, updated information on their success rates, technologies, or patient experiences.
Choosing a fertility clinic is a very personal and important decision. It requires extensive research and consideration of individual needs and preferences. I recommend that anyone seeking fertility treatment consult with their physician or seek out reputable resources such as the American Society for Reproductive Medicine (ASRM) to obtain unbiased information and make an informed decision.
