Embryos result when sperm fertilizes an egg. In gestational surrogacy, embryos are either created by the intended parents or by donors (egg, sperm or both).

No matter which method, embryos are created via In Vitro Fertilization (IVF). In this video, I discuss how IVF works, including the different steps and average cost (between $12,000 and $17,000 without medication).

IPs may want to consider preimplantation genetic testing on embryos – a test that involves screening cells from embryos for chromosomal imbalances.
