The fertility test i just ordered checks both men and women on a very basic level.
So the guy gets his sperm count checked.
The womens test isn't the same as an OPK.
OPKs test for LH which surges to cause a mature egg to be released.
The fertility test checks for FSH which is the hormone that makes the egg follicle mature in the first place.
A women can have an LH surge, but if there is no mature egg there, then no egg will be released even if your OPKs tests positive.
