Mexico IVF and Surrogacy is a valid option for US couples.
I have been looking into the cost of IVF and Surrogacy Worldwide. There are two websites that have some breakdowns available. They are ivfcost.net and at ivf cost worldwide.
The real value depends on what your needs are and what part of the world you live in. Travel expenses such as Hotels and airfare really add up fast.
From the USA, Mexico IVF appears to be a value price leader. The full fees for IVF and ICSI are only $4,000. Medication are in the $1,500 - $2,500 range. And there are round trip flights from almost all major US cities for around $300 round trip per person.
Many of the doctors are trained in the US and many clinics will let you bring your USA surrogate down to Mexico to transfer. With a surrogate from the US you only need to leave the country once for the transfer. The baby would be born in a US hospital with your normal doctor.
You can get the full treatment (IVF, ICSI, Meds, and Surrogate) start to finish for $20,000 - $30,000 and you only need to visit Mexico once. This is really a valid option that many people should explore.
