A1. Theoretically, the chances are the same for the first 3 attempts. However, in practice, we learn a little more about the patient each time we perform IVF. With the added information from each failure, we are able to tweak the subsequent cycle to try to improve the chances of success. So I'd say that the second attempt has a marginally better chance of success than the first.
A2. Its pretty routine to transfer frozen-thawed embryos before they divide again. However, I agree that waiting would provide additional information about the embryo's developmental capacity prior to transfer. In our program, we only transfer and/or freeze blastocyst stage embryos, so we know a lot more about there developmental capacity (compared to Day 3 transfer and/or freezing).
A3. If there is a suspicion of endometriosis, it should be diagnosed and treated before a subsequent IVF attempt. Endometriosis can and does affect the viability of transferred embryos and the implantation process. Endometriosis can be diagnosed by laparoscopy and treated by laser and/or medication. However, the endometriosis does eventually come back, so IVF should be attempted within 3 months of laparoscopy.
