Hi,
i havent had an appointment there but i can tell you what it is. its where you go w/fertility issues. Most centres also have in ivf clinic. I think its great you're going there cause you're going to the experts on fertility!! defenitely take all your notes and write down all the questions you might have as this will be when to ask,
best of luck and hope this helps
ps, I see you're in the UK so you could google it as most hospitals/nhs units have web pages about this stuff..xx
