Why the Catholic Debate Over the Morality of Saving Frozen Embryos Misses Some Important Points

I have welcomed and watched for some time the debate within the Catholic Church about the appropriateness of Catholics “saving” frozen embryos, which is a discussion  that has seen a recent resurgence. I admire both sides of the debate: those who are interpreting steadfastly the teachings of the Church regarding in vitro fertilization, as well as those good people who want to give frozen embryos a chance of life.

Didn’t the Vatican’s Dignatias Personae settle the moral issue?

The 2008 Vatican document Dignatias Personae (The Dignity of a Person), which was intended to provide updated directives on biomedical ethical controversies, may not have settled this moral issue to the satisfaction of all. Because the Catholic Church believes in unconditional respect for all human life from the moment of conception, to some, these teachings seem to be at odds with Catholics who want to save frozen embryos. Both sides, however, are missing an important point.

catholic IVF in vitro fertilization debateWhy some believe embryo donation/adoption is morally wrong.

Let’s start with the perspective from those who feel it is morally wrong for Catholics to participate in IVF, embryo donation or embryo adoption. While not an expert in any aspects of Catholic theology, I will try to list what I believe are the important talking points:

  • The Catholic Church feels IVF separates conception from the immediate act of sexual union between spouses while also improperly treating life as a commodity. IVF, therefore, is morally wrong and using fresh or frozen embryos created from such an act cannot be condoned or justified.
  • A husband has a spousal right within the marital bond to his wife’s body and no one but the husband should impregnate his wife. In mutual respect, their bodies belong to each other and no other.
  • Gestational surrogacy with donated/adopted embryos violates the covenant of marriage, as these pregnancies are not conceived through a natural act of conjugal love.

Some believe that IVF is morally wrong so using frozen embryos created via IVF cannot be justified.

Why some believe receiving a donated/adopted embryo is morally correct.

Next, let me next provide some of the arguments from those who feel that receiving donated embryos or gestating adopted embryos is morally correct:

  • Keeping the embryos frozen indefinitely is an ongoing injustice and affront to the embryo’s dignity.
  • Accepting donated/adopted embryos is similar to the adoption of a child, which is certainly encouraged by the church. Think of it as a “prenatal adoption”.
  • A women who adopts and is able to breast feed a child, which is allowed by the Church, is providing nourishment. One can then surmise that carrying a donated/adopted embryo in the womb, thereby providing nourishment is no different.
  • Surrogacy, under extreme circumstances, may be morally correct when a woman or the child would be severely harmed if the woman tried to carry and deliver a pregnancy.
  • Pregnancy occurs without having sex with another, so the marital bond remains intact.
  • Rescuing and receiving embryos ultimately protects the sanctity of life.

Others believe that life is sacred and that Catholics should be allowed to save frozen embryos.

Simply stated, those that believe it is immoral to receive donated/adopted embryos do not feel the ends justify the means when the means used, i.e., in vitro fertilization, is considered immoral. Those who believe gestating a donated/adopted embryo is moral ultimately feel the ends justify the means when the ends result in “saving” frozen embryos and building a happy family. This dilemma has divided a number of devout Catholics onto different sides of the debate.

What points are being missed in the debate?

Those against embryo donation/adoption also fear that the IVF industry will boom trying to resupply embryos. Nothing could be further from the truth. Frozen embryos are donated reluctantly with fewer than 10% donated to patients in need. Patients create embryos to build families of their own, not with the intent to donate or adopt.  A boom will never materialize and is not a realistic concern.

Some also are concerned that embryos would be created and sold to the highest bidder. Embryos must always be created with patients in mind. If not, we could potentially have banks of unclaimed embryos, created from both donor eggs and donor sperm waiting to be chosen. Potential human life is never to be bought or sold or should be left unclaimed waiting somewhere in a liquid nitrogen tank. The creation and sale of embryos is clearly, no matter what your religion, ethically inappropriate and utterly unacceptable.

One could also argue that fertile Catholics, with potentially large families, shouldn’t have priority to the donated embryos over infertile couples who have never had a family. I can tell you this is an important point to hopeful embryo recipients who are desperately searching for the limited number of donated embryos and a chance to even have a single child.

What is the most important point I feel is being missed in the Catholic debate?

While it is wonderful to watch the Catholic Church discuss these issues in ways it has not done before, the truth is that they don’t need to have such angst. The unfortunate reality is that the number of potential (non-Catholic) recipients far outstrips the number of embryos available. Frozen embryos, which are not used by those that created them, don’t need to be saved; they simply need to be donated. There are literally thousands of recipients that will gladly take them without reservation. Nearly all donated embryos will find a home without good Catholics having to wrestle with this difficult moral decision.

I truly appreciate the conversation that wonderful Catholics have had within their Church regarding this issue. I have nothing but respect for those that are discussing their concerns. The sad truth is, however, that it is a moot point.  From a practical perspective, we simply don’t have enough donated embryos to meet the current needs of the recipients who do not feel morally conflicted about the issue and who are not at risk from repercussions from a Church that maintains strong convictions. Perhaps if we significantly increase the number of embryos donated by decreasing the number abandoned or discarded, there would be a surplus of donated embryos and we would indeed need Catholics to rekindle the discussion.

To the good Catholics who are wrestling with this issue, feel free to keep the conversation going but be aware your participation, however welcome, thoughtful and well intended, is truly not needed to save the embryos you hold so dear. They are already spoken for.

Are Open Embryo Donation Procedures Better Than Anonymous?

open embryo donationGamete donation of sperm, eggs or embryos has been occurring for quite some time. Sperm donation probably occurred as far back as 1884 in the US (Wikipedia, 2011). Embryo donation was first reported in Australia in 1983 using both fresh and frozen embryos. (Trounson  A, Mohr L, 1983). Egg donation probably first took place in the U.S. in 1984 around the same time as the first embryo donation procedure (Blakeslee S, 1984).

Certainly in the early years of sperm/egg/embryo donation, the procedures were almost always done anonymously. Designated donations also took place using family and friends but they were the exception rather than the rule. Having donors and recipients meet was not really an option in the past.

Is non-anonymous sperm/egg/embryo donation becoming more common?

Over the years, there has been movement towards non-anonymous or known donations. Countries such as Sweden, Norway, Netherlands, Great Britain, Switzerland, Australia and New Zealand only allow non-anonymous sperm donations. In a future blog, we will cover some of the consequences that occur when countries completely move from anonymous to non-anonymous donation procedures. At least in the U.S., there is a choice, though Washington State recently passed legislation that makes it more difficult for anonymous sperm and egg donation to take place. I will discuss this legislation and topic in a future blog since this is an important and concerning development. An increasing number of donor sperm and donor egg banks offer non-anonymous donation, although, with rare exceptions, this remains a minority of the procedures performed in the U.S. (personal communication).

Does EDI offer non-anonymous embryo donation?

At Embryo Donation International, we offer Open Embryo Donation where the donors and recipients have the ability to communicate, meet and establish a relationship. Other facilities tend to call it “embryo adoption”, a term we are at odds with (click here for more information), where there is an attempt to foster relationships. Interestingly, at EDI, this is rarely requested although we feel it appropriate to offer such an alternative.

If embryo donors & recipients meet, what is the outcome?

If families do connect, there are a number of relationships that need to be considered. The first involves the donor(s) and the recipient(s). No one knows if these relationships will last. Romanticizing the idea of everyone being one happy family may be misguided. There are certainly examples where friendships have developed, such as the families profiled this Good Housekeeping article, but the number of relationships that don’t flourish are simply unknown. We all have to go through so many acquaintances to eventually find our true friends, so it remains uncertain if these initially awkward relationships will last beyond the transfer process. Long-term studies are lacking.

The second relationship to be considered would be with the resulting donor offspring and the donor(s). In an Open Embryo Donation procedure, the child will not only know the genetic and family history in detail but they will most likely know the names of the donor(s). The likelihood of this child trying to eventually connect with the donors is great. While there is a genetic bond, it remains uncertain if the relationship will always be welcome or beneficial. Certainly in the adoption world, adoptees that eventually find their family are not always rewarded with utter acceptance and may experience rejection, as they see it, a second time. Once again, long-term studies are lacking about the effects of an open embryo donation process with regards to the potential relationships between the donors and the donor offspring.

Lastly, there are the potential relationships between the siblings created when the donor has children of their own or donates to other recipients with offspring created. These children share a solid genetic bond and may feel rewarded in forming a relationship with their genetic brothers and sisters. Only careful, long-term and unbiased research will be able to identify the outcomes of such relationships. My best estimate is that these relationships may be sustainable but what will happen if the donor offspring are not fully accepted by the donors or the donors and recipients are no longer close?

Will my doctor be able to help me with my decision to have an open embryo donation?

So, would you want to meet your donor? Would you want to meet your recipient? It would be ideal if your clinician could clearly guide you as to the expected outcome of an open process. In reality, we are also diving into the thorny question regarding disclosure of one’s origins to embryo donor offspring, something that I will be touching upon in the months to come. For now, however, I suggest a point of caution. The world of embryo donation is simply not the same as the world of adoption and extrapolating one to the other is not without risk.

The issues we are discussing involve currently unknown long-term consequences and we need to be careful, thoughtful and unbiased in recommending one embryo donation procedure over another. For now, I believe it is a very personal decision that only embryo donors and recipients can make based on how they currently feel and what they believe will happen in the future.

I hope that we physicians deeply involved in the world of embryo donation will better be able to discuss the long-term advantages and disadvantages of open vs. anonymous procedures, but for now, the patients will simply have to guide us.

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.
