I reviewed A and D on 12 March. Unfortunately, the most recent IVF cycle resulted in the transfer of two embryos without pregnancy occurring. I have reviewed the details of their history since D's vasectomy in 1995 and reversal in 2005. On the four occasions they proceeded to IVF the first three resulted in satisfactory fertilisation (3:5, 5:6 and 2:3 oocytes fertilised). On the most recent occasion only 3:9 oocytes fertilised. There have been good quality embryos transferred now on five occasions, with one early pregnancy achieved but unfortunately early miscarriage.
