Embryo Donation

Who it’s for

Couples where neither gamete works. A woman with premature ovarian insufficiency or no ovaries whose partner has azoospermia, where no sperm is found even on surgical retrieval. Both partners carrying the same heritable condition.

Then people who come to it after several own-egg cycles, for whom a donated embryo is an affordable and realistic route to a family. That is a perfectly good reason, and worth saying openly to the clinic.

Eligibility is narrower than in the rest of donor conception. Programmes set their own rules about who may receive, and some, particularly the faith-linked ones in the United States, restrict it to married heterosexual couples. Single women and female couples are accepted by some clinics and turned away by others, so ask before you join a waiting list.

Some people have a better first option. Anyone who still has one working side, because donor eggs or donor sperm keep half the genetic link, which matters to many people. Anyone who has not had the uterus and lining properly checked, since a donated embryo will not fix an implantation problem. And if price is the main draw, it is worth giving the bigger questions a little time too.

Before you join a waiting list

Work out what you would want to be able to tell your child about where the embryo came from, then ask the programme how much of that it can actually give you. The answer is set by paperwork signed years ago, so it is good to know it now and plan what you will tell your child.

How it’s done

The consent and the matching take far longer than the medicine. Donors sign over embryos they created for themselves, and most jurisdictions let them change their minds up to the point of transfer. Screening is redone or reviewed, counselling is arranged on both sides, and only then is a lot released to you.

Your part is a standard frozen transfer. Oestrogen by tablet or patch for around two weeks, one or two scans to check the lining, then progesterone, which sets the date. Nothing synchronises with anybody, because the embryos are already in the freezer. The schedule is yours.

On the day the lab thaws one blastocyst. Good labs put survival at nine in ten or better. An embryo frozen at an earlier stage, or by an older method, is less reliable. Then a speculum, a soft catheter through the cervix under ultrasound, the embryo placed in the cavity, and you go home. Progesterone continues.

The things that shape the outcome are already set: grade, freezing day, whether they were tested genetically, the donors' age at the time. Asking about them tells you what you are being offered. So is the number in the lot. It is often one or two, rather than the six or eight a fresh cohort might give you.

Matching reflects that smaller supply. Instead of browsing a bank you are usually offered one profile and asked whether you accept it. Physical characteristics, ethnicity, blood group and family medical history, and rarely much beyond. Waiting lists of a year or more are common, and longer if you are looking for donors who are not white.

When a match is offered

Ask how many embryos are in the lot and what stage and grade each one was frozen at, before you say yes. A lot holding a single good blastocyst and a lot of weaker ones are quite different offers, and knowing which you have helps you plan.

After embryo donation

There is nothing to recover from. The transfer takes minutes, you rest briefly because the clinic prefers it, and you drive yourself home. Bed rest afterwards has been studied enough that clinics have stopped suggesting it. The hormones are the part you notice, and progesterone pessaries are messy but manageable.

Then a fortnight to a blood test, and with a donated embryo the wait has its own shape. People who use donor eggs tend to wonder whether the pregnancy will feel like theirs. Here the question is more often about the embryo's history, and about a couple somewhere who once planned a different life for it. For most people that thought settles naturally, often around the first scan.

It settles at different speeds for different people, so have a counsellor or a friend who knows the whole story to talk to.

While you wait for the transfer date

Write down everything the programme has told you about the donors, in full, while it is in front of you. A grown child will value the detail rather than the summary, and this is something lovely you can give them.

Risks and complications

This is the lowest-risk treatment in donor conception, because nobody stimulates their ovaries for it. No ovarian hyperstimulation anywhere in the chain. Your side carries the ordinary transfer risks and they are small: cramping, spotting, an awkward catheter passage, a low rate of infection.

The main one to plan for is a failed thaw. An embryo that does not survive warming ends that attempt, and if the lot holds one blastocyst, it ends the match. Ask what the programme does in that situation up front.

Donor egg pregnancies carry a higher rate of hypertensive disorders and pre-eclampsia, and the usual explanation is immunological, since the fetus is genetically foreign to the person carrying it. With a donated embryo it is foreign on both sides. Whether that raises the risk further is not established. The useful step is telling whoever takes over the antenatal care that this was a donated embryo, then asking them early what they will be watching, blood pressure included.

One point particular to this route is not medical. The donors often raised children from their other embryos, so your child may have full genetic siblings growing up in another family. A home DNA test can find them, so the decision worth making now is how and when your child hears that from you.

Embryo donation results

The odds follow the embryos, not you. Their grade, the stage they reached before freezing, and the donors' age when they were made set the ceiling. Your own age only matters for carrying the pregnancy. Figures for donated embryo transfers are generally quoted around a quarter to a third live birth per transfer. That sits below a fresh donor egg cohort and roughly in line with other frozen blastocyst transfers.

Check which measure you are being shown before you compare anything. Clinical pregnancy per transfer always looks higher. Ask for live births per recipient who started a cycle, over a defined recent period. Then ask how many of those recipients had more than one embryo.

The thing to plan for is the number of embryos. Fertility treatment gets its good cumulative numbers from having several embryos, and a lot of one or two gives fewer chances. If two transfers do not work, that is a normal outcome rather than a sign anything went wrong, so it is wise to budget for doing this more than once.

Alternatives to embryo donation

Double donation is the closest thing and it is often confused with this. It uses fresh donor eggs fertilised with donor sperm, created for you. That means a whole cohort, real choice over both donors, and screening you commission rather than inherit. It also costs several times as much. The distinction is that one uses embryos which already exist, and the other makes them.

If one side still works, that is where to look first. Donor sperm with your own eggs, or donor egg IVF with your partner's sperm, keeps half the genetic link and a shorter waiting list, which many people value highly.

Adoption belongs on the list too. It answers a different question, since it is not about pregnancy, and it carries its own long assessment. Some people looking at donated embryos find that what they want is a child rather than a pregnancy. They go that way instead.

And if the genetic link is the sticking point, a counsellor is the right person for that conversation, because it is a family question rather than a treatment one.

Embryo donation cost

The expensive half of donor treatment has already been done. Somebody else paid for the stimulation and the collection, and what a programme bills you for is the transport of the embryos, the screening, the legal work and the transfer itself. That is why the headline is low, and why it pays to ask what else the attempt involves.

Ask what the quoted figure covers, because programmes draw that line in different places. Your own medication usually sits outside it. So do the counselling sessions both sides need, the screening bloods, the lawyer who checks the consents, travel to a programme that may be nowhere near you, and storage of anything left in the lot while you decide what to do with it. A non-profit charging administrative costs only covers its own administration, so add the rest to get the full picture.

Then ask about a second attempt. Ask whether a thaw that fails counts as a transfer you have used, what the programme charges to release a further lot, and whether you rejoin the waiting list at the back.

The most useful comparison is cost across the whole plan rather than per transfer. A lot holding one embryo gives one chance, so compare it fairly with a larger cohort, in time as well as money.

Choosing a clinic for embryo donation

There is no surgeon to pick here. What you are assessing is a matching service and the paperwork behind it. The two numbers I would ask for are how many embryos a released lot holds on average, and how many recipients went home with a baby after using up a whole lot. Those two figures tell you how many chances one match typically gives you, and a well-run programme will have them.

Then ask where the embryos come from. Whether donating couples had implications counselling at the time. Whether they were told a child might one day contact them. How the embryos were graded, and by whom. Some of these embryos were frozen a decade ago, so the paperwork from that time is worth checking carefully.

Ask about the list too, plainly. How many families are waiting, how long the last few matches took, and what happens if a thaw fails. Then the question I would not leave without. Ask what your child will be able to learn at eighteen about the donors, and about the children the donors went on to raise themselves. That answer is already written down, so it is good to know it now.

At the consultation

Ask when the donating couple's consent becomes final, and what the programme does if they withdraw it the week before your transfer. Every programme has a policy, and hearing it early means you are prepared.

Frequently asked questions

Is this the same as embryo adoption?

Same treatment, different word. Most legal systems treat it as a donation of tissue rather than an adoption, and the programmes using the other term often have stricter recipient criteria. See who it's for.

How is this different from double donation?

One uses embryos that already exist; the other creates them for you from fresh donor eggs and donor sperm, with more choice and a much higher price. See alternatives.

Will there be genetic siblings?

Often yes, because the donors usually kept embryos and raised children from them. Assume your child can find them through a DNA test. See risks.

Are we the legal parents?

In most jurisdictions the woman who gives birth and her partner are the legal parents, provided a licensed clinic treated you and consent was signed first. Confirm it for your own country before you start.

Does my age affect the success rate?

Only for carrying the pregnancy. The odds come from the embryos and the donors' age when they were made. See results.
