Human Embryonic Stem Cell Research – Reimbursement Debate

Should Patients be Reimbursed for Donating Their Embryos for Human Embryonic Stem Cell Research?


By Dr. Craig R. Sweet

Introduction:

There are a handful of academic and private research facilities in the U.S. performing human embryonic stem cell (hESC) research. The use of embryos for research is an emotionally charged issue, with prolife and prochoice proponents having opposite viewpoints. The advantages and disadvantages of the research are not the focus of this discussion. EDI feels this is a very personal choice, which only should be made with great care and thought.

Let us assume for now, and at the risk of offending some, that there is potential merit to hESC research.

Most Donors Change Their Minds

Approximately 71% of the patients who state they will donate their unused embryos routinely change their minds, with most discarding them instead (Klock SC, et al. 2001). In fact, only about 5-10% of the patients actually donated their unused embryos for hESC research (Elford K, et al. 2004 & Klock SC, et al. 2001). Why do so many change their minds?

Would the percentage of embryos donated for research increase if donors were given a minimum level of financial reimbursement?

Inappropriate Enticement?

Centers performing hESC research are under very strict guidelines. Institutional review boards for human experimentation, which oversee such studies, forbid any level of coercion in obtaining embryos. Coercion can mean many things, including offering excessive financial incentives. But in my opinion, restricting even small tokens of appreciation can be counterproductive. For example, when we worked with Harvard’s hESC lab, we wanted to offer patients a $25 gift card to encourage them to complete the paperwork within 30 days so we could transport the embryos to the study facility as quickly as possible. Soon after starting this, we were told to stop because even a $25 gift card might be interpreted as inappropriate enticement.

Does anyone really think the $25 would inappropriately convince a patient to
donate their embryos for hESC research when they would otherwise not have done so?

How Much Do Embryos Cost?

In a pilot study performed by our parent organization, Specialists In Reproductive Medicine & Surgery (SRMS), we found the average cost per embryo transferred or cryopreserved was $2,400. This study included patients with and without insurance coverage. These estimates didn’t include the costs of time away from work, pain, suffering or any other infertility treatment expenses leading up to the IVF procedure. Interestingly, the cost per embryo transferred or cryopreserved ranged from $650 to $23,000.

What if the reimbursement was always far less than the amount that was spent to create the embryos, to make certain no one ever created embryos for profit?

Will Researchers Benefit?

Is there any doubt that academic centers and private companies may benefit from hESC research? If there is a scientific breakthrough at a hESC research facility, isn’t it reasonable that they will benefit from research dollars and/or actual profits? Even the American Medical Association’s (AMA) Council on Ethical and Judicial affairs states: “Profits from the commercial use of human tissue and its products may be shared with patients, in accordance with lawful contractual agreements.” (AMA, Opinion 2.08)

Is it wrong to ask why the patients who provided the embryos shouldn’t be reimbursed for even a fraction of what it took to create them?

What Do Patients Think?

In Netwon’s 2003 paper examining attitudes towards embryo donation procedures, 16% of those interviewed rejected embryo donation without some reimbursement with another 32% uncertain. (Newton CR, et al. 2003). This is compelling evidence that some patients felt the embryos had worth and that a level of reimbursement was not only desired, but required.

What Did You Think?

We conducted a poll on Facebook asking: “Should patients be compensated for donating their embryos for human embryonic stem cell research? Why or why not?” The following were the results:

  • No: 11 people (69%)
  • Uncertain: 2 (12%)
  • Yes: 3 (19%)

While not a very large poll, the overriding opinion was no. I certainly respect their view. Clearly, reimbursement is not appropriate for all. I can’t help but wonder, however, if it would be appropriate for some.

Why Not Reimburse?

I suggest that reimbursement for research studies is commonplace but seems to be forbidden in hESC research. What makes it so different? Facilities conducting this research are under a magnifying glass and most likely are afraid of criticism regarding human embryos. Are they afraid of a public relations backlash? Perhaps they truly feel it is ethically inappropriate, even though participants in other forms of clinical research; sperm, egg, and blood plasma donation; and surrogacy and adoption are reimbursed or compensatedfor reasonable and customary expenses and time and effort. But any suggestions about reimbursing for human embryos seem to be taboo.

Will Reimbursement Reduce the Number of Embryos Discarded?

So will adding a small financial incentive change human behavior and reduce the number of embryos discarded? Would a study exploring this clear institutional review board perusal for human experimentation oversight? Simply posing the question won’t work as people change their minds about embryo disposition. A randomized, multi-center longitudinal study might answer the question. In this study, some patients would be reimbursed and others not, with the number of embryos donated to patients in need or research would be compared to the number that were ultimately discarded.

Will anyone be brave enough to initiate such a study?

In Summary

What if a small amount of money was provided for embryos destined for hESC research? If reimbursement was provided, the research facility would need to require documentation of the money spent to create the embryos. It would be absolutely necessary that the facility always pay far less than it ever took to create the embryos. We must make certain that no one would ever create the embryos for profit, something I feel is overwhelmingly inappropriate.

Those who do not feel comfortable with reimbursement could simply refuse or request a donation be made to charity. Since we currently are forbidden to reimburse patients for embryos donated to patients in need at EDI, we instead donate to charity in either the donor’s name or anonymously. It is the best compromise we could find.

Perhaps fewer embryos would be discarded, abandoned or perpetually cryopreserved if we motivated patients with direct reimbursement or donation to charity. If we did so, might the greater good be served?

How Long do Embryos Last?

By Corey Burke, B.S., C.L.S.
Embryologist & Andrologist
Laboratory Supervisor

I am often asked: “How long do frozen embryos last?” The answer to this question is a little more complicated than simply replying with a specific number of years because several factors influence the answer.

The first successful pregnancy from a cryopreserved (frozen) embryo occurred in 1983 (Trounson A, Mohr L. 1983). Shortly thereafter, embryo cryopreservation became commonplace, with millions of embryos cryopreserved over the past few decades. Recently, a live birth was reported from an embryo cryopreserved for 20 years (Dowling-Lacy D, et al. 2011). There is, however, uncertainty regarding the health of frozen embryos over time. Since embryologists have only been cryopreserving embryos for slightly less than 30 years, it is impossible to know right now if extended storage times much beyond two decades will influence embryo survival and pregnancy rates.

A study that is the largest of its kind was recently published in March 2011. It examined approximately 12,000 cryopreserved embryos, and determined that the length of storage time did not influence post thaw survival rates or the actual pregnancy outcomes (Riggs R, et al. 2010). The embryos in this study had been frozen up to nine years.

The technique for freezing embryos in liquid nitrogen has changed over time. The original method was known as a “slow freeze” technique, where the temperature of the embryos slowly dropped over a couple of hours. Vitrification, a newer method, freezes the embryos in a minute fraction of a second. While survival rates for embryos frozen through vitrification seem higher, it is uncertain if vitrified embryos will result in more pregnancies (Khoury C, et al. 2010). My guess is there will actually be little difference between the two freezing methods since the embryos end up in the same suspended animation of liquid nitrogen at -196°C (-321° F). If the embryo survives the thaw, pregnancy rates may not depend on the duration of time it was frozen or the technique used to freeze it.

While there clearly are many variables that influence the health and implantation rate of an embryo, the length of storage is probably not one of them. Data still needs to be collected but the information we have so far is encouraging.

As time marches forward, I expect additional cases to be reported that will lengthen the 20-year cryopreservation “ceiling” to decades longer. Amazingly, it is estimated that mammalian cells will last for hundreds or even thousands of years when frozen in liquid nitrogen (Mazur P. 1980). If this is true, these frozen embryos will certainly outlast all of us.

The Frozen Embryo Dilemma

Are Disposal Ceremonies or Compassionate Transfers the Answer to the Frozen Embryo Dilemma?

By Dr. Craig R. Sweet
Medical & Practice Director
Founder, Embryo Donation International

In recent years, researchers led by Dr. Anne D. Lyerly of Duke University have conducted several studies about infertility patients’ attitudes toward disposition of excess frozen embryos. Their research has shed some light on the difficulties facing patients about this important decision and patient reaction to the different options clinics offer.

As a quick review, options for excess frozen embryos are:

  • Personal reproductive use
  • Donation to research
  • Donation to patients in need
  • Thaw and discard

Timing has a significant impact on patient decision-making. Clearly, the in vitro fertilization (IVF) process can overwhelm patients. First, they’re worried about whether they will create embryos and, then, about how many of them will be high quality. Then after the transfer, they endure the long wait while hoping and dreaming for a positive pregnancy test and an encouraging ultrasound weeks later. The last thought on their mind involves the eventual disposition of excess frozen embryos. It is probably unreasonable to expect patients to make this type of decision, but most fertility clinics ask them to select an option before they even start of the IVF process. Many patients stated that from the start the IVF clinics didn’t do a good job in explaining their choices (Lyerly AD, et al 2008). While this may be true in some instances, clinics may have explained the alternatives well, but patients simply couldn’t absorb all the information. When forced to decide what to do with the cryopreserved embryos before they have successfully delivered a child through IVF and/or have made the decision to stop treatment, many patients will inevitably change their minds.

It would appear that almost half of all the estimated hundreds of thousands of cryopreserved embryos are not used for reproduction. We found this to be true in our own 2006 internal review and others have published similar statistics. As I have written before, the decision regarding what to do with excess cryopreserved embryos is very difficult such that 15% of the patients choose to not decide and keep their embryos frozen indefinitely (Lyerly AD, et al. 2011).

Many patients don’t like any of the existing alternatives for frozen embryos. A disposal ceremony at the time of thaw and/or a compassionate transfer may be better options. A compassionate transfer occurs when the embryos are placed into a women’s uterus or vagina at a time when she can’t conceive. Some patients prefer this process, letting the embryos be absorbed naturally and allowing closure while honoring what has been described as the physical and emotional attachments between them and their embryos (Lyerly AD, et al. 2006 & 2011). One of the rare studies to examine if patients would choose compassionate transfer found that about 20% would consider this alternative (Lyerly AD, et al. 2010). In a separate but associated article written by the same author in 2011, she stated:

“Given the morally difficult nature of the disposition decision, informed consent is unlikely to be the full solution: ensuring options that patients find responsible and respectful, such as compassionate transfer or a disposal ceremony may benefit those who assign high moral status or value to the embryos but are disinclined to donate them to another couple.”

There are, unfortunately, three problems with these two options. The first is that very few facilities offer these disposal techniques (Gurmankin AD et al. 2004). Second, I can’t help but wonder who is receiving the compassion, the patients (probably) or the embryos? Third, no matter how you phrase it, the embryos are still being thawed and discarded.

Let me be clear that the parent organization of Embryo Donation International (EDI), Specialists In Reproductive Medicine & Surgery, P.A. (SRMS), removed the destruction option for excess frozen embryos years ago, believing that better alternatives existed. I feel the embryos deserve an intermediate level of respect and that donating them to research (human embryonic stem cell or other valuable studies) or donating them to patients in need serve a greater good for the embryos and society as a whole. We try to make this as clear as we can to the patients undergoing IVF at SRMS, emphasizing our non-destruct policy in our consent. Interestingly, over the years, not one patient or couple has disagreed with the policy. Our desire is that other facilities consider what we call our “non-destruct” policy.

EDI/SRMS’ views are currently in the minority, with the majority of IVF programs still allowing patients to thaw and discard their embryos (Gurmankin AD et al. 2004). While I would far prefer that patients consider donation to research or patients in need, as a clinician, I have to be aware that my personal and professional views may differ significantly from others.

Perhaps the facilities that continue to offer the thaw and discard option would consider offering alternatives that some patients really want. It would seem a disposal ceremony consistent with the patient’s religious or spiritual beliefs or a compassionate transfer are two options patients prefer but rarely seem to be able find.

I still implore patients with excess cryopreserved embryos to consider embryo donation and to pay it forward to other infertile patients traveling the difficult infertility road without success. From my perspective, the best option is to take a deep breath and make the difficult decisions that will not result in the discarding of their cryopreserved embryos. If, however, a disposal ceremony or compassionate transfer will result in embryos not being abandoned or frozen forever, then perhaps this is a marginally better option to consider. Marginally better, but still in my mind, not the best of the options readily available.

Understanding that the reimbursement would probably be limited, should patients be reimbursed for donating their embryos for human embryonic stem cell research?

Safe Travels on Your Infertility Journey

By Dr. Craig R. Sweet, Medical Director & Founder

I sit here wondering what I can write about that others will not already be commenting on during this very busy and important National Infertility Awareness Week for those traveling the infertility journey. But after over 20 years of taking care of tens of thousands of patients, I have developed a few philosophical perspectives and “rules of the road” and I want to share with you.

Don’t Wait Until All Your Ducks Are in a Row
First, a woman’s ability to conquer the world does not necessarily transfer to conquering the biologic clock that endlessly ticks forward. My IVF patients already are arriving at my doorstep at an average age of close to 37, which puts them at a significant disadvantage. If I could encourage young women to do anything, it would be to try to start their families earlier. If they wait to have all their “ducks in a row,” they may never see their little ducklings.

Hollywood is rife with women conceiving late in life, but they rarely tell anyone that they used donated eggs, not that it is our business. Please, I implore women around the world to have their children sooner and not depend on our modestly advanced technologies to prevail when nature argues differently.

Seek Knowledge Sooner Rather Than Later
Second, if you are having problems conceiving, see a knowledgeable local reproductive endocrinologist sooner rather than later. Don’t be pressured to start a more intensive evaluation or procedures one day earlier than you are ready but seek knowledge sooner. Obtain an opinion from someone you trust to see where you stand and to get a glimpse into your reproductive future. At the risk if alienating some referring physicians, do not be satisfied with seeing general OB/GYN physicians or Urologists to seek solid information should problems be found. Knowledge is power; obtain it quickly with experts who live and breath your issues each and every day.

Don’t Be Afraid of the Unknown
Third, don’t be afraid of what you might find. Take a deep breath and learn the truth. I see far too many patients that fear for too long, only to find out their fears were incorrect, or that their delay significantly impaired their overall chances for success while inadvertently increasing their costs to succeed. Be brave, find support and gain knowledge quickly. Do not be afraid. This is absolutely directed at both the male and female patients.

In Closing
I will leave it up to RESOLVE and many other organizations to do what they do best: organizing patients to speak with one united voice during this very important week. During this week of attention, a philosophical perspective may really be of some benefit hopefully heard among the din of all the other conversations.

Infertility is a journey and what journey should start without a few rules of the road?

  • Lisa:

    Great advice Dr. Sweet.I wish I had known a lot of things sooner.When talking to others about infertility I always tell them not to wait.I did and regret it everyday.Not only do I wish I had started sooner,but wish I had found you sooner.I hope to be seeing you again soon.

    • Thanks, Lisa, for your support and for visiting our blog. Pass the word/link to the blog. It would be great if women in their early 30’s could read it before too much time passes.

      I hope to see you again soon as well. Take care. CRS

The Disposition of Cryopreserved Embryos

By Dr. Craig R. Sweet, Medical Director & Founder

During in vitro fertilization (IVF), numerous eggs are removed from the woman, and fertilized with sperm to create embryos that are grown in the laboratory for several days. Almost always the final number of embryos available for transfer is less than the number of eggs (oocytes) originally retrieved from the woman.

For example:

  • 12-14 oocytes retrieved
  • 10-12 mature ooctyes (available for fertilization)
  • 8-10 oocytes successfully fertilize with sperm
  • 3-6 embryos survive and are available for transfer or storage in liquid nitrogen for future useembryo in liquid nitrogen

From the few embryos left on day five of fertilization, we try to transfer the smallest number needed to achieve a pregnancy. Approximately, one-third of the patients will have enough extra embryos to freeze for future use.

These embryos may last for decades frozen in liquid nitrogen (Mazur P, 1980). For many, deciding what to do with the embryos is a very difficult decision. In general, the following options exist:

  • Thaw and transfer for personal use
  • Donate to science
  • — Human embryonic stem cell research
  • — Other valuable studies
  • Discard
  • — Thaw and dispose
  • — “Compassionate Transfer” into a uterus at a time when implantation cannot occur
  • Donate to patients in need (i.e., embryo donation)

Many, but not all facilities, offer the “discard” option. We believe that better choices exist than destruction and no longer include it in our patient consents. The actual options available to a given patient may be more limited than the list above.

There are many reasons patients do not use the embryos for personal use (Kirkman M, 2003):

  • They have completed their family
  • Past pregnancy complications
  • Age
  • Emotional exhaustion
  • Cannot afford further treatment
  • Divorced

Many find deciding the next steps for their cryopreserved embryos to be exquisitely difficult. I feel that all reproductive facilities could perform far better at counseling patients and assisting them in making these decisions. Patients have complained that we haven’t done an adequate job (Nachtigall RD, et al., 2005). I suspect they are right. I believe it is the responsibility of the cryopreservation or reproductive endocrine facility to educate patients adequately and offer assistance and information when requested. EDI designed a brief brochure to address these very issues.

If one is really uncertain and the personal use of the embryos is still a possibility, then I agree that the embryos should be stored longer, but not indefinitely. If, however, additional family building has been ruled out, then I advise the patient to take a deep breath and make the difficult decision that ultimately must be made.

My patients put so much, emotionally and financially, into the creation of their embryos. Our goal is to support them through the difficult decision, no matter what they decide. I can only hope they will consider either human embryonic stem cell research or embryo donation. I personally believe embryos deserve a heightened level of respect. These two possible destinations serve a common and greater good for everyone involved. While human embryonic stem cell research holds some future promise, the immediacy of growing a family though embryo donation seems to be the best choice for those wonderful and precious gifts, a donors’ embryos.

Welcome to Embryo Donation International

Hello and welcome to the Embryo Donation International blog! We will be discussing all things related to embryo donation – the process, guidelines, regulations and the tough decisions that go into the final decision.

Who is Embryo Donation International (EDI)?

Embryo Donation International (EDI) is a subdivision of Specialists In Reproductive Medicine & Surgery, P.A., which has been providing embryo donation for 10 years making us one of the most experienced embryo donation facilities in the country.

Our mission is to reduce the number of cryopreserved embryos abandoned or discarded by assisting in the matching embryos to patients in need regardless of race, religion, ancestry, sexual preference or marital status. We turned this philosophy into Embryo Donation International.

I started creating our embryo donation program in 2000 and had our first delivery in 2001. I have always enjoyed the field of reproductive ethics, which helped to form many of my philosophies regarding embryo donation. In speaking out against embryo abandonment and the discarding of embryos while speaking out in favor of human embryonic stem cell research, my reproductive endocrine practice began to form the core values we now hold so dearly here at EDI.

A Human Embryo

At EDI, we believe that the embryos deserve a heightened level of respect; placing them between common cells and the patients we treat. We feel this is a type of gentle embryo advocacy. We believe that they should be used for a common good and have the opportunity to build a family.

For more information, please view the About Us section of the blog or visit our website www.EmbryoDonation.com.

What sets EDI Apart from other Embryo Donation Organizations?

EDI is non-discriminatory. We welcome healthy recipients including single women, homosexual couples, cancer survivors and people of any race or ethnicity. While we believe all healthy embryos deserve a chance at life and that healthy individual deserves a chance at parenthood, we are not a faith-based facility.

We are dedicated to making the process of embryo donation affordable. Our fees are roughly 50-60% less than many alternatives. We also accept embryos from around the world.

Additionally, we have a growing database of embryos (which is available for reviewing at no cost) and we offer them through a variety of means – approved, anonymous and open embryo donation procedures– based on the donors’ wishes and the recipients’ willingness to participate.

We look forward to offering tools for donating or receiving, or simply helping you learn more about the options available along your infertility journey, which we all hope will end with parenthood.
