Happy, I aso have endometrosis and had 1 ovary removed. But that didn't stop my chances with my 1st IVF attempt. So don't lose hope yet.
As for your hubby, you will need his support and cooperation during this period, esp when it comes to him supplying his little soldiers for ER. Perhaps you need to speak to him further to understand what are his real concerns? Though IVF is not natural, but if your cycle is successful, the baby belongs to both of you.
When I first told my MIL that we were going to try IVF, she was against it, but that's coz she tot that the kid may not be our own (either me + someone's else sperm or the opposite). So, we spent some time to explain to her that the kid will be a part of me and my hubby, but we jus need the extra help (IVF) to deliver a grandchild to her as we have tried naturally on our own for some times without much success....
