If a woman had her tubes tied could she still be surrogate mother for another couple?

No, a woman who has had her tubes tied cannot be a surrogate mother for another couple. Tubal ligation is a surgical procedure that permanently cuts, ties, or blocks the fallopian tubes, which are the pathways that eggs travel from the ovaries to the uterus. This prevents eggs from being released into the uterus, making it impossible for the woman to become pregnant.

Therefore, a woman who has had her tubes tied would not be able to carry a pregnancy for another couple, even if she were to receive an embryo through in vitro fertilization (IVF).
