Double Donor Treatment Explained
Understanding Double Donor Treatment
Double donor treatment is a fertility option in which both donated eggs and donated sperm are used to create an embryo.
For some people, this is the best treatment option when pregnancy isn't possible using their own eggs or a partner's sperm. Although there is no genetic connection between the intended parent(s) and the embryo, the recipient carries the pregnancy, gives birth and becomes the child's parent from the very beginning of their life.
You may also hear this treatment referred to as donor embryo treatment, although there are important differences depending on how the embryo is created and transferred.
What Is Double Donor Treatment?
Double donor treatment uses an egg donated by one person and sperm donated by another.
There are two main ways treatment may take place:
Fresh Double Donor Cycle
The recipient's menstrual cycle is carefully synchronised with the egg donor's cycle. The donated eggs are collected, fertilised with donor sperm and the resulting fresh embryo is transferred into the uterus a few days later.
Frozen Donor Embryo Transfer
Alternatively, an embryo that has already been created using donated eggs and donated sperm (or donated by another family following IVF treatment) is thawed and transferred during a Frozen Embryo Transfer (FET) cycle.
Your fertility clinic will explain which approach is most appropriate for your circumstances.
When Might Double Donor Treatment Be Recommended?
Your fertility specialist may discuss double donor treatment if:
Your ovarian reserve is extremely low or absent.
You have premature ovarian insufficiency (POI).
Severe male factor infertility is also present.
Previous IVF treatment has been unsuccessful.
There are genetic conditions that you don't wish to pass on.
Other fertility treatments have not resulted in pregnancy.
The decision to use both donated eggs and donated sperm is deeply personal, and many clinics offer specialist counselling before treatment begins.
How Are Donors Matched?
Many fertility clinics try to match donors and recipients as closely as possible based on physical characteristics. The exact matching process varies between clinics and countries.
Depending on the clinic, matching may consider:
Height
Build
Hair colour and texture
Eye colour
Skin tone
Ethnic background
Blood group (where appropriate)
Educational background
Interests and hobbies
Personality traits
Some clinics also ask recipients to provide photographs of themselves from childhood through to adulthood. These photographs may be used alongside other information to help select egg and sperm donors whose appearance is as similar as possible.
The aim isn't to create an identical child, but to find donors whose characteristics broadly resemble those of the intended parent.
How Successful Is Double Donor Treatment?
Success depends on several factors, including:
The age and health of the egg donor.
Embryo quality.
The health of the uterus.
Your overall reproductive health.
Your fertility specialist will discuss your individual chances of success based on your circumstances.
Emotional Considerations
Double donor treatment can bring a wide range of emotions.
Many people experience hope alongside grief, excitement alongside uncertainty.
Some worry about not sharing DNA with their child or wonder whether they'll feel like a "real" parent.
These feelings are completely normal.
For many parents, those fears gradually disappear as pregnancy progresses and, later, through the experience of raising their child.
Advantages of Double Donor Treatment
Offers an opportunity to experience pregnancy and childbirth.
Can help people who cannot use their own eggs or sperm.
Donors undergo careful medical and genetic screening.
Can provide excellent success rates in appropriate circumstances.
Limitations of Double Donor Treatment
Double donor treatment isn't suitable for everyone.
It involves emotional, legal and practical considerations, and pregnancy can never be guaranteed.
Taking time to understand your options and access counselling can help you make an informed decision.
Frequently Asked Questions
Will my child be genetically related to me?
No. Both the egg and sperm are donated. However, you will carry the pregnancy, give birth and become your child's parent.
Can I breastfeed after double donor treatment?
Yes. Most people who give birth following double donor treatment can breastfeed if they choose to do so.
Is double donor treatment available in the UK?
Availability varies between clinics and NHS funding criteria. Some people choose to have treatment overseas.
Can fresh and frozen embryos both be used?
Yes. Some treatments involve transferring a fresh embryo created specifically for your cycle, while others use embryos that were frozen previously.

My Story
A Personal Perspective
This article is especially close to my heart because my own journey involved double donor treatment, using both donated eggs and donated sperm.
My treatment involved a fresh double donor cycle. My menstrual cycle was carefully synchronised with my egg donor's cycle. After her eggs were collected, they were fertilised using donor sperm that had previously been frozen, and a fresh embryo was transferred into my uterus a few days later.
One part of the process that many people don't realise is how carefully the donors were matched.
My clinic asked me to provide photographs of myself from childhood through to adulthood, along with details about my height, build, colouring and other physical characteristics. They also considered factors such as education, interests and aspects of personality when selecting both the egg donor and the sperm donor.
I found the process fascinating.
At first, I wasn't sure how much the matching would matter. Looking back now, I appreciate the care that went into finding donors who closely resembled me. While genetics don't define my family, it was reassuring to know that so much thought had gone into the process.
Before treatment, I worried about whether I'd feel like a "real" mum because we wouldn't share DNA.
Today, I can honestly say those fears disappeared the moment my twins were born.
The love I feel for them has never depended on genetics. It has grown through every kick I felt during pregnancy, every sleepless night, every cuddle, every milestone and every ordinary day we've shared together.
If you're considering double donor treatment, know that it's completely normal to have questions and mixed emotions. I had them too.
Looking back, I realise that becoming a parent wasn't about sharing DNA. It was about sharing a life.
A Gentle Reminder
Every family has its own story, and there is no single "right" way to become a parent. Whether your child is conceived naturally, through IVF, using donated eggs or sperm, or through double donor treatment, what defines a family is the love, care and commitment you share. If this treatment becomes part of your journey, remember that it's okay to take your time, ask questions and seek support. The path may be different from the one you first imagined, but it can still lead to the family you've always hoped for.
