Could he be the problem?

Hi all, for those who have gone to the Dr for ttc, what kind of Dr did your spouse/so go to see?

We haven't gone to the Dr yet because my pcp has told me to wait after a year of trying to see a Dr about it. I know it could very well be me, but I don't really think it is. I've been pregnant twice before with my ex husband. With my husband, we have been married almost 2 years and have been actively trying for the past 6 months, at least I have. He's rarely in the mood. All the stars need to line up in the sky correctly just for him to be in the mood. I honestly think he's suffering from low T. Are there any other couples here that have this problem? And what did you/your Dr do about it?
