Explain the difference between surrogacy and adoption.
What will be an ideal response?
Surrogacyis an alternative form of reproduction known in which a woman (the surrogate) is impregnated and carries a fetus to term and agrees to turn the baby over to a woman, man, or couple who will raise it. Single parent, same-sex couples, and couples in which one or both members are infertile choose surrogacy. Sometimes the surrogate carries a zygote composed of one or both of the couple's gametes. Other times the ova, sperm, or zygote are donated. Adoption involves bringing a nonbiological child into a family, and it does not involve any medical procedures. Single parent, same-sex couples, and couples in which one or both members are infertile can choose adoption.
