Yeh that's a bit different I think. I think if the doc had suggested an invasive test that wouldn't really change the outcome my hubby wouldn't have been keen. In his eyes it was just a simple blood test and another sperm analysis so it's worth it to him to know.
I certainly wouldn't wanna undergo investigative surgery that really doesn't have much point. I'm already annoyed we're at the IVF stage. I've had 9 general anesthesias in my lifetime and I'm only 30. Having to do IVF when there is nothing wrong with me was the last thing I wanted
