surrogate mother

...Artificial insemination, which was once used primarily as a treatment for cases where the husband is infertile, has expanded to cases where the wife is also infertile due to the popularity of DIY methods. In other words, the husband artificially inseminates another woman with the husband's sperm to create a child for the husband and wife, creating a "borrowed womb" or "surrogate mother."
