Surrogate pregnancies recently gained more popularity, mostly among the celebrities. Surrogate is a woman who gets artificially inseminated with the father’s sperm. She then carries the baby and delivers it for you and your partner to raise it. The average cost of surrogacy can range from $90,000 to $130,000 depending on the individual arrangements. In States like California, where surrogates are in high demand, the cost may be much higher.
