About this business

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 Michael Guarnaccia at Extend Fertility? Dr. G was alway honest and realistic during my treatment. There were many times where my body was not responding to the course of treatment and instead of pressing me to go forward he would always give me the choice of wether I wanted to continue going forward knowing that the chances of an optimal result were low or to stop for this cycle and then try again next cycle. It made me feel good knowing he was more concerned with the result as opposed to just co... read more

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
