Hey.

I can't really advise you on when to change - I don't know what the repercussions would be between DR Lok and you and your current FS.

What I can tell you is that we were referred to Dr. Lok especially because he deals with male infertility issues and SIVF have all the onsite facilities to deal with all the sperm stuff (as apposed to having to take samples and then trasport them off site for analysis etc.)

I may have told you before - but I rate Dr. Lok very highly. He didn't muck about - we went straight to ICSI. No trial and error trying other type of AC. We are now 10 weeks & 3 days pregnant off our first cycle of AC. We also have 3 frozen day 5 blasties.

I don't know if he will treat you better than your current FS. We only met with Dr. Lok a couple of times and the rest was organised via the nurses, but I felt very comfortable knowing that he was reviewing all my BT's and scans and in the end it has all worked as planned.

I don't know if I have helped at all with your dilema. Maybe it's worth speaking to Dr. Lok and asking him if it is normal for people to change at the stage you are at? Basically, it comes down to what YOU want and what YOU feel comfortable with. YOU are the one paying them.

Good Luck.
