I don't have a preference now that I am not having any more children. As a check-up it makes no difference to me. I have 2 girls and each pregnancy was a different doctor. My first daughter I had female mid-wives who were really cool, had their own children so they knew what to expect and they were very understanding. During labor, they were very comforting and all about waiting on the child to be ready. The mid-wife who delivered her didn't want to cut me to hurry it along, she kept telling me to try to hold out on pushing a couple more contractions to try to prevent me from tearing. A little tear happened anyway, but she was very cool and professional about the whole situation. She waited for Dad to come over to cut the cord knowing it was important to him. She did what she could to make sure I was comfortable even tho she had a couple ladies in labor at the same time. She came in and out until my daughter was ready to come.
Now for the male doctor, he was professional and knew what he was doing. He was a bit impatient tho. Instead of waiting a few more contractions, he decided to cut me (I had no anesthetic in me, no pain relief and was not numb) which hurt like you don't want to know!! I can't even explain what that felt like without having any pain medicine or anesthetic in me. But I guess my daughter was taking "too long" to come and he couldn't wait a few more contractions. Then he cut the cord before Dad could have a chance to come over and do it. My honey sat back out of the way, but close enough to be there. The doctor should have waited for him to cut the cord.
It may have been my experience, but if I were to have another baby it would be a female doctor. But as I said, for a check-up I don't care male or female.
