What is the cost of IVF in Mexico?

I know a couple who recently got IVF in Mexico and they were claiming to have saved around 60% in costs quoted by their local doctor.

Obviously, the costs vary by clinic standards but even the best clinics offer IVF (including medications) for around $7,000 - $8,000.

I've mostly heard good things but also some concerns, but as I understand low-cost IVF in Mexico is possible because of the lower rents, lower wages of doctors and staff, cheaper medications, affordable food, lodging, and everything else that is priced moderately.
