A more thorough explanation:

Definition: ART stands for Alternative Reproductive Technology, which is a way for people who are unable to have children naturally to have a baby. It includes different methods such as in vitro fertilization, sperm donation, ovum donation, and using a surrogate carrier.

Examples:

• In vitro fertilization (IVF): This is when an egg is fertilized by sperm outside of the body and then implanted into the uterus.
• Sperm donation: This is when a man donates his sperm to be used by a woman to become pregnant.
• Ovum donation: This is when a woman donates her eggs to be used by another woman to become pregnant.
• Surrogate carrier: This is when a woman carries a baby for another person or couple who cannot carry a pregnancy themselves.

These examples illustrate how ART can help people who are infertile to have a child. It allows them to use different methods to conceive a baby and start a family.
