I will tell you that I have been diagnosed with a severe case of antisperm antibodies . . . basically I produce massive amounts of antibodies that attach to sperm heads and make it impossible for me to conceive naturally. However, I've had this for a while, so I don't know why it would be particular to my husband. I do agree on getting checked out, but it may just be one of those things. For me, since I know I can't conceive naturally I just wash out everytime we have sex and it does help the odor some. What's annoying for me is that I really don't have any sort of odor on my own, which I'm glad about, but the two of us together cause a problem.
