The poster had a good point. It’s expensive and people want the highest % of success. I can understand that . If you don’t have a choice though prices will come down or people will pay the fees, if it’s what they really want.
When you're looking at proposed therapies on a case-by-case basis, this is the question to ask: does this heal the physical causes of marital fertility and restore natural sexual procreation? OR does it give up on healing and instead substitute some non-marital, non-sexual process for the marital relation?
In many cases of infertility, the would-be mother and father are both technically fertile (they produce normal ova and sperm and could conceive via intercourse) but have not been able to get pregnant or to maintain a pregnancy.
A true therapy would have found a way to optimize natural fertility (often by addressing nutritional and hormonal preconditions, or by fine-tuning the pattern of sexual behavior) so as to preserve true marital procreation --- instead of substituting another man as the genetic father or intruding laboratory procedures into the relationship.
Actually treating the couple's marital fertility problem is preferable to cutting out the genetic contribution of one marriage partner, or taking lovemaking out of the equation.
Renee Mirkes, the director of the Center for NaPro Ethics, reports that "in the long run, NPT is 1.5 to 3.5 times more effective in achieving conception than conventional IVF treatment."
And it restores the fertility that the married partners jointly have, without the enormous expense of ART and wit5hout the emotional, social, and psychological costs.
Here's a second highly informative link on NaProTechnology for healing of natural fertility.
