Hi, I used LEB so just want to add my experience. Overall, it was very good and I recommend them highly. Much better and with better patient care than a previous private clinic I used.
I purchased 10 eggs, got 11, and ended up with 4 embryos. The first three transfers failed, and I'm 20 weeks pregnant with the last (and "worst") embryo.
I had been hoping 10 eggs would give the chance of a sibling as they suggest on the website. However, my donor has just donated again, so it is a positive sign that LEB has returning donors.
I felt very supported throughout the process, and they went above and beyond to address concerns.
My only disappointment was that they don't recommend additional investigations into implantation until you have two failures, because there isn't a reason, statistically. There was no clinical reason for me to have those investigations because my own eggs implanted, and I personally wasn't worried. In future, I would always do the implantation clinic before transferring any precious embryos. Once I went through their implantation clinic, I had one more failure before my pregnancy. Of course, the three failures may have just been bad luck!
