How old do you have to be for in vitro?

In vitro fertilization (IVF) can be pursued by individuals or couples of various ages, but most clinics typically require the female partner to be at least 18 years old to undergo the procedure. There is no upper age limit for IVF, but success rates generally decline with age, particularly for women over 35. Many clinics also have specific guidelines related to age, health, and fertility factors to assess eligibility. It's best to consult with a fertility specialist for personalized advice.
