Sorry to hear this. After a few failed cycles clinics want you to leave as it affects their statistics. Make sure you check the sperm and have dna fragmentation done to see if there is an issue there. He might need additional vitamins minerals, life style changes and that could improve your chaces. It takes 3months to make a sperm. Maybe he might need to have antibotics before collection incase there is an underlying issue. Have you checked the timing of the transfer? The moment you loose faith move on. You will find the right clinic.We have just done a cycle of own sperm / donor eggs, we got 3 blasts and all have been transferred with no successes. The clinic l was happy enough for the 1st transfer, thought we might have got more than 3 blasts though. For the 2nd transfer they seemed very apathetic about it all. There were only changes because l requested some changes e.g. increase progesterone and add Prednisolone.
It is fairly obvious we won't succeed naturally so we are weighing up another round. Im inclined to try another clinic who are more motivated and driven, the current clinic seemed to get quite checked out. They have been increasingly disorganised as well. They are aware the last transfer failed, l have asked to discuss changes for next time to assist us weight up our options. They haven't replied and l am not willing to chase them.
