Success rates for Women 44-52 years old

“You will always have this dream, now when you are in your 40s, and you will still have this dream if you do not let it happen, when you are in your 50s or 60s. The difference is in that when you are in your 40s this dream may still become a reality! Always follow your dreams and goals! The only regrets we have are the ones we don't follow through!”

Therése Neaimé


At OLGA Fertility, we understand that the desire to become a mother does not fade with age and even grows stronger. And we also know that with latest advancements in reproductive medicine, women in their late 40s and early 50s now have realistic chances to achieve not only a successful pregnancy, but a healthy live birth. We are here to support you on this journey with our scientifically proven, safe, and effective approach to your fertility treatment.

Proven Results

The latest data we collected in OLGA Clinic (2019-2022) demonstrates that women in their upper reproductive age have a high chance of achieving a successful pregnancy and delivering a healthy baby within Egg Donation programmes:

Out of 439 embryo transfers performed in women aged 44-52, 217 resulted in live births – a 49% success rate.

There was no statistically significant difference in live birth rates between women aged 44-45 (51.0%) and those aged 48-52 (47.4%).

The majority of deliveries in both groups occurred at full term, indicating healthy pregnancies.

74.7% of deliveries in the 48-52 age group and 88% in the 44-45 age group took place after full 37 weeks of pregnancy.

There were no extremely preterm births (before 28 full weeks) in either age group.

Positive attitude towards pregnancy in mature age in contemporary medical literature

Medical research and clinical experience confirm that with proper screening and care, pregnancy at an older age can be both safe and successful:

  1. The risk for the mother and the child can be reduced by careful medical screening of the future mother and ensuring optimal health status prior to conception.
  2. If a donor egg is used, an older woman can carry a pregnancy with a similar risk compared to younger patients
  3. Complications in pregnancy do not mean poor outcomes of pregnancies; e.g. higher rates of cesarean sections in premature delivery are not translated to increased mortality
  4. Many maternal complications are temporary and effectively treated
  5. Women in good health have lower rate of pregnancy-related morbidities, independent of age.

OLGA Clinic’s Approach to Safe and Efficient Treatment

By combining OLGA’s proven expertise in achieving high success rates with the latest medical research, we have developed specialized treatment protocols for patients aged 44-52. These protocols are designed to maximize success while ensuring the safety of both a mother and a baby:

  • In-depth health check for the future mother enabling her to identify and optimize her health risks prior to pregnancy
  • In-depth  health check for potential egg donors in the best interest of the future mother and future child
  • Personalized fertility treatment plans tailored for a successful embryo transfer and a healthy pregnancy
  • Single embryo transfer policy to minimize the risks related to multiple pregnancies
  • Continuous medical support, including one-to-one consultations with our midwives and obstetricians throughout pregnancy

100% Money-Back Guarantee for Women Up to 51 Years Old

Our experience in safe and efficient fertility treatment for women of upper maternal age has enabled us to increase the age limit up to 51st birthday by the first procedure within our Egg Donation Packages with 100% Money Back Guarantee of live birth.
