Not me but very interesting.

They tested me for mycoplasma and ureaplasma. I had never heard of either so I searched on the 'net. Not a lot of information out there on either. Apparently, they can be similiar to chlamidya, but it's not an STD. I think, I may be wrong, that everyone has it, but it's bad when you have too much.

There isn't much about it on line at all, you're right. I googled "mycoplasma infertility" and got this:
Of women being evaluated for infertility, 40% are infected with chlamydia, mycoplasma or ureaplasma, as are 36% of those with a previous history of uterine infection and 50% of those with tubal blockage. More than 60% had evidence of a past infection (9). The more partners you have, the more likely you are to be infected (10), although you can be infected by one contact (11). An infection can prevent pregnancy by blocking the uterine tubes (12,13,14). It can damage sperm (14A), so they can't swim toward the egg (15), and it can cause abortions, premature birth and low birth weight (16,26,27,28,29). Infected people may have burning on urination, discomfort when the bladder is full or an urgency to void. Women may have only spotting between periods (17).
***I guess I'm just surprised that Dr.'s don't test for it when couples are having difficulty conceiving???? If it's just a simple urine test, why not do it?

Never heard of it. I agree, if it's a simple urine test, why not do it and get it outta the way?
