This document discusses the controversy surrounding surrogate motherhood. Surrogate motherhood involves a woman carrying and giving birth to a baby for another woman who cannot conceive. While surrogacy has helped many infertile couples have children, it remains illegal in some countries and U.S. states due to ethical concerns. There are two types of surrogacy - traditional where the surrogate uses her own egg, and gestational where another woman's egg is implanted. Around 22,000 babies have been born via surrogates in the U.S. since the 1970s, though views on its legal status still vary greatly.
