What does ROPA mean?

ROPA stands for:

Reception of Oocytes from the Partner’

It allows a woman to donate her eggs to her female partner who, with the help of IVF treatment with donor sperm, carries the baby during pregnancy and gives birth.

With the ROPA method, both partners have an important role:

  • One becomes the genetic mother because she contributes the eggs,
  • The other carries the pregnancy to term and becomes the birth mother.

During pregnancy, the latter will be able to contribute to influencing the child’s development via epigenetics

This process is unique to lesbian pregnancy options as it allows both partners to share the experience of conception and pregnancy equally.

Who is reciprocal IVF suitable for?

Reciprocal IVF is specifically for lesbian couples who want to share the whole process of creating a family.

It works best for couples where:

  • One woman has healthy eggs, and
  • The other woman has a healthy uterus where the embryo can attach (implant) and the pregnancy can develop.

Reciprocal IVF is particularly suitable for:

  • Lesbian couples where both partners want to be actively involved in the conception and pregnancy.
  • Lesbian couples where one partner does not want to be pregnant, but still wants to be biologically involved in the pregnancy.
  • Cases where one partner has a medical condition affecting egg quality or the ability to carry a pregnancy.

If you live abroad and wish to travel to Denmark together for treatment, we can assist with synchronising both your menstrual cycles. This ensures that your bodies are at the same stage in the menstrual cycle, so that the egg retrieval and subsequent transfer of the embryo happen at the optimal time.

If it becomes necessary to adjust or reset one or both of your cycles, this can be done with various hormone supplements.

The partner providing the eggs will undergo hormonal stimulation to encourage the ovaries to produce more eggs. Ultrasound scans will monitor the development of the eggs. When the eggs are ready, a trigger injection is given 36 hours before egg retrieval, which is performed under mild sedation.

Once the eggs are retrieved, they are fertilised with donor sperm in the laboratory.

The embryos are closely monitored by our embryologists until they reach the blastocyst stage (5-6 days post-fertilisation). 

At this stage, a blastocyst is ready to be transferred to the partner’s uterus.

Alternatively, we can freeze blastocysts for later transfer in a so-called frozen embryo cycle. If there are multiple viable embryos, we can freeze the extras for future use – for additional attempts or for siblings.

Before the embryo is transferred, the partner carrying the baby will be prepared with either hormone injections or medication to ensure the womb is ready for implantation.

Once prepared, the blastocyst is transferred into her uterus through a simple, pain-free procedure.

10 days after egg transfer, we measure your HcG level to check if the treatment has been successful.

What is the success rate of reciprocal IVF?

The success of reciprocal IVF largely depends on the quality of the eggs and the health of the partner carrying the pregnancy.

In particular, the age of the woman providing the eggs plays a crucial role. In general, the younger the woman providing the eggs, the higher the chance of success.

We continuously update our success rates on our website.

What is the main advantage and disadvantage of reciprocal IVF?

The main advantage of reciprocal IVF:

The most important benefit of reciprocal IVF is the sense of togetherness it fosters through the shared experience of creating a child.

Fertility treatment can be an emotional journey filled with both hope and uncertainty.

Many couples find strength in going through this journey together, supporting each other along the way.

The co-IVF method with partner egg donation allows lesbian couples to share this experience, with both partners contributing.

This can strengthen their bond with each other and to their future child.

The main disadvantage of reciprocal IVF:

The main disadvantage of reciprocal IVF is that the treatment is more invasive and expensive than may be necessary to have a child.

The vast majority of women are healthy and have no fertility challenges. So, most lesbian couples can fulfil their dream of having a child through a simple insemination (IUI) with donor sperm.

Advantages of IUI:

  • IUI is cheaper and less invasive compared to reciprocal IVF treatment.
  • IUI can be performed in your natural cycle – without hormones.
  • The insemination treatment where purified sperm is placed in the uterus is a very simple procedure without significant risks.

The epigenetic influence of the birth mother

New research in the field of epigenetics shows that the mother carrying the baby plays a significant role in the child’s development.

While the genetic traits come from the egg and sperm donors, the prenatal environment – including the mother’s nutrition and mental state – impacts how the baby’s genes are expressed.

This means the birth mother has a profound influence on the baby’s early development.

Legal considerations for reciprocal IVF

Legal for everyone from 1 January 2025

In Denmark, partner egg donation has been legal for all lesbian couples since 1 January 2025.

This means we can now offer reciprocal IVF treatment to everyone, regardless of whether there is a medical reason for it or not.

No marriage or sperm donor category requirements

In Denmark, there is no requirement to be married to receive the treatment, unlike in many other countries.

There are also no restrictions on the choice of sperm donor in Denmark. You as a patient can choose your donor.

We will of course be happy to guide you, if you are interested.

See our Diers Selected sperm donors

Co-motherhood

The woman who gives birth to the child will be considered the child’s mother under Danish law.

 

If you are not both Danish citizens residing in Denmark, we recommend seeking legal advice before beginning treatment to clarify your rights and obligations regarding legal parenthood or co-motherhood.

Frequently asked questions about reciprocal IVF

Yes. One woman provides the eggs, making her the genetic mother, while the other carries the pregnancy and is the birth mother. If the couple later swaps roles, they can both be biological mothers to their own child.

Yes, the vast majority of women develop a strong bond with the baby they carry, regardless of genetic connection. Pregnancy plays a significant role in building this bond, as you nurture, protect, and give life to the baby. Your body also influences the baby’s development through epigenetics, and the emotional connection naturally deepens during pregnancy and parenthood. It is your care and love that create the unbreakable bond between you and your child.

It is completely natural to have questions or concerns about bonding when undergoing fertility treatment with egg donation. Give yourself space to process your thoughts and feelings, and consider speaking with someone you trust for support.

The whole process usually takes a few weeks, depending on how the two women’s menstrual cycles synchronise.

Yes, a sperm donor is needed to fertilise the eggs. Both open and closed sperm donors are available, and the clinic also offers treatment with a known sperm donor, typically a friend or family member of the couple. 

Success rates vary and depend on factors such as the age of the woman donating the eggs, the quality of the eggs and the health of the woman carrying the baby.

Research shows that after becoming pregnant through egg donation treatment,  there is an increased risk of pre-eclampsia and high blood pressure. Our doctors will explain this in more detail during your consultation. Read more about the risks of IVF with donor eggs here.
