OUR STORY Extend Fertility was founded on the premise that democratizing egg freezing could ultimately change the fertility industry and deliver better results. Our co-founder, Dr. Joshua Klein, was a reproductive endocrinologist and fertility specialist at one of the nation’s leading fertility practices. However, he observed that IVF’s low success rate for women over 40 and its high cost was disappointing for doctors and patients alike. Dr. Klein saw the opportunity to help women think more proactively about their fertility. He believed that if more women could access their younger eggs during the IVF process, more women would see successful outcomes.

Once you pay them, you will NOT see a doctor again until your operation day. To be clear, you may only see any doctor before you sign up, when they try to sell you their service. When my doctor...
