In vitro fertilization (IVF) offers several benefits for couples facing infertility. It increases pregnancy chances for those with blocked tubes or male factor infertility, and helps with unexplained infertility. IVF allows genetic screening to prevent inherited disorders, supports single parents and same-sex couples, and enables embryo freezing for future use. It also permits donor egg or sperm usage and tailors treatments to specific fertility issues, providing a versatile solution.
