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 ferti... read more

How was your experience with Joshua Klein at Extend Fertility? Dr. Klein is a great communicator. As I mentioned before, it’s necessary to provide the patient with statistics; however, he never left me without hope. I had my frozen eggs fertilized and it resulted in 5 embryos. I sent it out for PGS testing with 4 coming back abnormal and 1 inconclusive. He was willing to transfer the inconclusive as that is what I wanted- which did not lead to pregnancy. I then went through an IVF cycle and he was able to retrieve 10 eggs. A... read more

How was your experience with Bat-Sheva Maslow at Extend Fertility? Dr. Maslow was extremely helpful in explaining the complicated elements of a pleasing to me.

There’s a lot of basic information that nee... read more

How was your experience with Joshua Klein at Extend Fertility? Joshua Klein did a wonderful job of making me feel like a human, instead of a number. I live in Chicago, but after our initial consultation, it was a no-brainer that I needed to fly to New York to have him do the procedure. I am so happy I did. He participated in every office visit. He took the time to educate me on each decision (timing, medication, etc.) and each step. One day, a nurse forgot to call me with dosage instructions. Dr. Klein called me, himself, to... read more
How was your experience with Bat-Sheva Maslow at Extend Fertility? When you go to Extend Fertility, it feels more like you are a patient of the clinic then any patient of a specific doctor. I only met her once during a consultation and was once seen by a different doctor during the routine visits. She did not do my retrieval. She was really nice and knowledgeable and patiently answered my questions. During treatment, were you treated like a number or a human with Bat-Sheva Maslow at Extend Fertility? It's a smaller office, b... read more
How was your experience with Joshua Klein at Extend Fertility? I did not see Dr. Klein very much through the process, once at consultation and then again at the retrieval, but I did not really feel like I needed to see him that often, given that I was only doing an egg retrieval. He was very pleasant and kind when I did see him though. One thing I feel kind of unsure about is that when I told him that I knew that the success rate of freezing and thawing eggs was not as high as freezing and thawing embryos, he disagreed with ... read more
How was your experience with Joshua Klein at Extend Fertility? He was very knowledgeable and intelligent, and inspired confidence in his decisions. While this approach may not be comforting to everyone, I appreciated his analytical perspective and focus on the data and statistics. I like information and expertise, and I never felt as if I was lacking in either of those during the course of my treatment. What's one piece of advice would you give a prospective patient of Joshua Klein at Extend Fertility? Expect to see a wide v... read more
How was your experience with Joshua Klein at Extend Fertility? I loved working with Josh Klein. He gave me very honest feedback and set my expectations. Other doctors wanted to run so many tests (many were invasive) to try to diagnose the problem or put me on meds (like Lupron, which I refused) to try to correct something that hadn't even been diagnosed. Dr. Klein listened to my story and focused in on the one problem that had been identified a year earlier - scarring - that we thought had been solved (two visits to Dr. Isaa... read more
