Attention to Detail

Attention to detail is on a 1 - 10 scale, and is scored based on the rate, and severity, of errors committed by the clinic according to the patients.

For example, a severe error might be failing to inform a patient of critical information, while a small error might be failing to call a patient with results.

CDC Success Rates

This is the most recent data from the CDC. The CDC cautions that it should not be used to compare doctors and clinics.

For more information please see our FAQs.

Where you see a “?” on the chart, a clinic has done fewer than 20 cycles in this category and age range, so the CDC says showing percentages from this small data set would be misleading and unreliable.

I am seeing Dr. Maslow for egg freezing.... Dr. Maslow was extremely helpful in explaining the complicated elements of a pleasing to me. She was easy to talk to you even when my results were not so great in the beginning stages. She was encouraging but honest throughout the process, which I really appreciated.... She also went through other hypothetical AMH blood levels with me and how that might impact my anticipated results.
Extend Fertility provides egg freezing exclusively, so I found the prices are lower than other clinics for this very specific service. They used to offer free consultations and diagnostic testing, but now they charge $250 and if you end up using them to freeze your eggs you get to apply that amount to the cost of your egg freezing cycle.... There was one time when I showed up for a blood test that the nurse told me my test wasn’t on the calendar.

What's one piece of advice would you give a prospective patient of Bat-Sheva Maslow at Extend Fertility?
I would come with a list of questions for her. There’s a lot of basic information that needs to be told every single patient but beyond that it really is up to you to do your research and make sure you ask the right questions so that you get the answers you need to feel comfortable with your personal care.
During treatment, were you treated like a number or a human with Bat-Sheva Maslow at Extend Fertility?
She sat down with me face-to-face for a full hour and thoroughly went through my test results with me. She also went through other hypothetical AMH blood levels with me and how that might impact my anticipated results.

There was one time when I showed up for a blood test that the nurse told me my test wasn’t on the calendar. But it turned out not to be an issue. They were able to get me in but I was told that my appointment did not show up for them.

He [Dr. Klein] 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.... I only have one embryo to transfer, but he said he did not like to risk losing multiple embryos in one shot, along with the risk of multiples.
Because much of this new practice is still entwined with the egg freezing practice (Extend), there is a high volume of patients, but Dr. Klein and his team ensured that there was a personal quality to visits and treatment.... It's busy, and I did feel like I had to follow up with certain aspects of treatment (e.g., making sure the pharmacy had my medication orders, etc.). I think this may have been because I began my cycle on a holiday, however.

Describe the costs associated with your care under Joshua Klein at Extend Fertility.
They are about half as much as other clinics, and they are also very clear in advance. I previously did IUI cycles at another clinic and they ended up costing about three times what I was told to expect. There were no surprises with Expect.

  • Failed to call in prescriptions to pharmacy
  • Lost paperwork
Describe the specific things that went wrong at Extend Fertility.
I started the day after New Year's Day, so the pharmacy did not have my order, and they also kept thinking that labs that I had previously submitted were missing. It is early stages for this branch of the clinic.

One thing I feel kind of unsure about is that when I told him [Dr. Joshua Klein] that I knew that the success rate of freezing and thawing eggs was not as high as freezing and thawing embryos, he disagreed with me and said otherwise. I am pretty sure that it is a known fact, but since his entire clinics business model is freezing eggs, I'm sure he feels that he has to believe this.
Extend is mainly for people who want to freeze eggs, so you will not have as many interactions with him [Dr. Klein] as you might if you were going through the full process of IVF, etc. I thought he was fine for the purposes of egg freezing, patient and answered questions throughout the process, but it was really the staff and the educational materials on Extend's website that were the standout for me.
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.

During treatment, were you treated like a number or a human with Joshua Klein at Extend Fertility?
I liked the Extend Fertility, the nurses were very sweet and kind and the clinic was never full. I never had to wait very long for my appointments, and the staff was very kind and understanding.
Describe the protocols Joshua Klein used in your cycles at Extend Fertility and their degree of success.
I have PCOS so I wasn't on the shots for very long - maybe a week and a half before they triggered with Lupron.
Describe your experience with the nursing staff at Extend Fertility.
As I said, the staff was really the standout here. They were really compassionate, always available, and very pleasant.
Describe your experience with Extend Fertility.
The clinic is really nice, and there was never a long wait. I felt like I was going to a spa every time I visited. Very new, sterile, and modern. The educational materials they have available on their website are awesome. Everyone going through the IVF process should read those materials b/c they do such a good job of explaining it in a way that you can understand.
Describe your experience with your monitoring appointments at Extend Fertility.
It was really easy to make appointments, always available before work, and never had to wait long to get seen.
Describe the costs associated with your care under Joshua Klein at Extend Fertility.
W extend, you pay around $5K. When I shopped around, it would have cost me at least $2K more to do it at a "normal" clinic.
What specific things went wrong at Extend Fertility?
  • Failed to call with results
Describe the specific things that went wrong at Extend Fertility.
The only thing I wish that they did was send me paperwork to confirm the number of eggs retrieved. But when I called and asked for it, they sent it right away.

Dr. Maslow cares about her patients and women's education around fertility. She is passionate about what she does and wants her patients to have positive outcomes. She communicates over the phone and over email.... We agreed to do 2 cycles of egg retrieval (I am 40) and we would determine if a third is necessary. After the 2nd, we agreed to a 3rd but she was confident that completing a 4th cycle was unnecessary.
Communication [Extend Fertility] was problematic and obtaining records was an issue. The steps of the process were not made transparent. Ex. How long would the eggs be stored in the clinic and then shipped to the storage facility was not readily available. Had to request that details be made in writing. For example, they called you over the phone to tell you the number of eggs that were going to be frozen but did not offer a written confirmation of the record unless I requested.

Dr Klein is very nice...But the methods they use are so aggressive and ineffective. They are very rigid with statics, and treat every patient like how a textbook would instruct. They try to pump as much medication into you as possible, hoping to get the best results. But it turned out to be very counterproductive and I am afraid its harmful to my body in the long run. And the results are so poor. I only got 50% of mature eggs the first time, and the second time half of the eggs magically disappeared ( I think they ovulated earlier because the doctor was late!)
I wish someone had shared their experiences with Extend, so I could have skipped my 2 cycles with them, and saved my ovaries Dont take me wrong, Dr Klein is very nice. The clinic is pretty well organized. (Dr G is a different story. Very rude and impatient ) But the methods they use are so aggressive and ineffective. They are very rigid with statics, and treat every patient like how a textbook would instruct. They try to pump as much medication into you as possible, hoping to get the best results.

I only got 50% of mature eggs the first time, and the second time half of the eggs magically disappeared ( I think they ovulated earlier because the doctor was late!) They use manupor unnecessarily. They ask you to inject full dose of ganerilx every shot. They don't time well the ovulation Window. They just rigidly go by the 36 hours rule. (I strongly suspect in the second cycle, the missed the ovulation window, and lost half counts of my eggs. Because the count of eggs was only half of what the unltrasound indicated. But the doctor was not willing to tell me why. They tried to hide the reasons. I even got yelled by doctor G for asking about the reason ) I only found out how these things are wrong after I went to New Hope for my third cycle this month. I was pretty skeptical about them at the beginning, and even wanted to go back to the extend. The extend sells them well for all the charts and statistic based result predication But at New Hope, they customize the medication for you. I didn't have to use manupor. They minimize both the ganerilx and trigger shots. I felt less influenced by the drug during the whole cycle. And the result was better. New hope is not the best. For example, they could have given me the wrong trigger shot medication if I didn't triple check with the nurse. just for a full disclosure But if I could have done it again, I wouldn't have gone to the extend at all. I feel really regretted, not for the money, but worried about how all the cycles might have impacted my health. But it's my fault that I didn't do a thorough research first. So I just want to share the experience here. I hope it will help someone who is going through the same situation-- egg freezing
