Extend Fertility is a New York-based fertility services provider focused on egg freezing and IVF within a small, data-driven practice. The company was founded to broaden access to egg freezing and to improve outcomes by enabling patients to take a more proactive approach to their fertility rather than letting time determine results.

Founded by Dr. Joshua Klein, a reproductive endocrinologist, Extend Fertility began with egg freezing and later expanded to offer a full range of infertility services. By 2017 it had become the largest egg freezing practice in the country, while maintaining a personal, high-quality clinical environment driven by data. In late 2023, Extend Fertility formed a partnership with Gameto to advance women's reproductive health.
