I did a few google searches by typing these criteria in:
infertility and antibodies
how to test for anti bodies+infertility
blood test for antibodies+infertility
treatment for antibodies+infertility
Also google antisperm antibodies (asa)
So many sites to choose from, the top most looking rather technical.
In the last search I did, the treatment for included low-dose aspirin (baby aspirin) and heparin. Interesting.
I used to have all these things bookmarked but this was way back when ttc my DS and the year was 1998 when I was just learning what the heck FSH stood for. Took my 4yrs of combing through what the internet offered and bringing printouts to my RE who would take the papers and say, oooookay, we can test you for these and no, won't do it. and never once allowed me to try injectables. That still burns me; somehow she always dissuaded me.
I'd expect an RE to test for these if, like in your case, you keep getting negatives. I'd just want to rule out antibodies.
I think Drs usually test only if it's recurring m/c. but in our IF world, we see too many IF women trying and trying and it just makes me wonder that what if the problem is antibodies and they are doing what they are doing in the very early stages so there's not even time to be called a chemical pg. The Drs would totally miss it. As far as I know, it's tested with a blood test.
I've also heard of a woman being allergic to her partner/husband's sperm which would cause IF and that using a condom for 2-3mos will reset things because there wouldn't be repeated exposure to the "allergen". But one of the symptoms to this is clear, you'd feel like you have a slight fever right after BD. Have you heard of this?? The human body can be so odd: allergic to sperm. my word.
and once again, I am thinking how great it would be if people going through IF had advocates who would go with them to see their REs and get the best treatment plan going for them asap, none of this "let's try this and come back in 3mos or your next cycle" business. all the waiting drive me nuts, such precious time slipping away when I wanted that baby yesterday, thank-you-very-much. (oops, am I ranting??) An Advocate who would know oodles of info and would say to the RE, ok, yes BUT what if blah blah blah instead of patient limping home to nurse the battered self and then muster the courage to once again go online for another tidbit to help things along.
ok, done with my rant.
