The maximum age for undergoing in vitro fertilization (IVF) in the United States is typically determined based on the individual’s overall health and fertility status rather than a strict age limit. Generally, the optimal childbearing age for humans is between 25 and 35 years old, and IVF procedures are often recommended within this age range for optimal outcomes in terms of both successful conception and maternal health recovery. However, if the optimal childbearing window has been missed due to various reasons, it’s not necessarily a cause for undue concern, as age alone is not the sole determining factor.

The eligibility for IVF in the United States primarily depends on the physical condition of both partners, including factors such as ovarian function, hormonal levels, immune system status, uterine and reproductive tract health for females, and sperm quality for males. IVF in the United States falls under advanced assisted reproductive technology and has specific indications and contraindications. However, as long as the ovarian follicles develop well and the egg quality is good, age may not be a limiting factor.
