The post coital test was the first one Dr H did for me when I started seeing him. The results of the first test were inconclusive so he got us to repeat it.

Basically, you have sex and then the next morning, you go to the doctor who takes a speculum and removes a sample to look at under the microscope. It's pretty painless and it's good to know if your mucus and DH's sperm don't seem to agree. At least a course of treatment can then be plotted (this is the reason I'm having AI).

You're right, it does sound undignified but I think once you head down this road, you pretty much have to leave your dignity at the door. I've lost all of mine now and even I can't believe how little I care.
