What is Mitochondrial Replacement Therapy (MRT)

MRT energizes your eggs by replacing compromised power sources with healthy donor mitochondria, while still preserving your own DNA. This approach targets egg quality issues that often lead to repeated IVF failures.

There are two techniques for MRT

Pronuclear Transfer (PNT) and Maternal Spindle Transfer (MST). Our medical support team will discuss your unique needs and which of these techniques will serve you best.

Pronuclear Transfer (PNT)

Pronuclear Transfer (PNT) and Maternal Spindle Transfer (MST).
Our medical support team will discuss your unique needs and which of these techniques will serve you best.

mitochondrial replacement
  • The nucleus from a fertilized egg containing unhealthy mitochondria is transferred into a donor egg with healthy mitochondria.

  • The donor egg’s nucleus is removed before the transfer, ensuring that only the intended parents’ DNA is passed on.

  • This process results in an embryo that carries the parents’ genetic material but benefits from optimal mitochondria, increasing the chances of a successful pregnancy.

mitochondrial replacement
  • The nucleus from the mother’s egg is removed and placed into a donor egg with healthy mitochondria.

  • This technique ensures that the embryo retains the mother’s genetic material while being powered by strong, functional mitochondria from the donor egg.

  • MST is particularly beneficial for women whose egg quality has been compromised due to age or mitochondrial disorders.

Why MRT can transform your fertility journey

  • Keep your DNA

    Your child carries your genes, not the donor’s.

  • Boost Egg Vitality

    Healthy donor mitochondria can overcome egg-quality challenges.

  • Lower Inherited Risks

    Replacing compromised mitochondria may reduce certain disorders.

  • A Possible Last Resort

    Renew hope when standard IVF no longer seems to work.

Key statistics that inspire hope

Below are brief facts and figures about our MRT program. They may offer reassurance when you have gone through multiple IVF cycles.

  • As of February 2025, 34 babies have been born through MRT, with families from 32 countries.

  • The oldest MRT child is now over 7 years old.

  • Most MRT patients are between the ages of 39 and 52 when egg quality becomes a common concern.

  • A 48-year-old patient carried and delivered her baby through MRT.

  • Several patients over 50 are accumulating zygotes, proving it is never too late to try.

  • Many MRT patients are 42 to 46 and wish to keep their genetic connection.

  • We typically begin MRT with 4–6 eggs or embryos. Patients who produce fewer eggs (1–4) may benefit from our MINI program, while those able to bank more (4–15) are eligible for our full program.

We’ll take a close look at your hormone levels, cycle history, and goals to see if this could be the right next step for you.

“I had a wonderful experience with the International Fertility Group (IFG). They are thoroughly professional and will go all out to make your dream come true. Kesenia from IFG has really been an inspiration and she assured me and was an inspiration to the success. We were blessed with a beautiful baby boy whom we named Ian and it is all thanks to IFG and their team of highly professional individuals, doctors, laboratory personnel and other staff without them we would never have been parents.
I will highly recommend IFG to any potential parent. Ksenia is a wonderful coordinator and made us feel welcome and went through the process in a professional way. Even though I could not thank each of of the team, my heart goes out to them in saying a big THANK YOU.)”
