O.L.G.A. Clinic has been helping many women achieve successful pregnancy and live birth in mature age and has acquired lots of expertise in making this process safe and successful. Before becoming pregnant at O.L.G.A. Clinic, all women undergo robust medical examination by several specialists, detailed laboratory testing of their body functions and treatment to improve their chances and reduce their risks.


We reviewed our data at O.L.G.A. Clinic for the past 5 years.

The age group 48-52y.o.

In 2019-2022 O.L.G.A. Clinic has done 192 ETs in women 48-52y.o. using donor eggs or donor embryos.

91 out of these 192 embryo transfers resulted in live birth (47,4% Live Birth Rates)

We know exact term of delivery in 88 out of these 91 deliveries:

  • 65 deliveries at term 37 weeks+ (73,9%)
  • 20 deliveries 36-33 weeks (22,7%)
  • 3 deliveries 32-31 weeks (3,4%)

▸ No deliveries before 31 weeks

▸ MR 14,2%, only before 12 weeks

The age group 44-45y.o.

In comparison we look at the group of women who receieved embryo transfers at the age of 45-46 at O.L.G.A. Clinic in St. Petersburg in 2019-2022 

O.L.G.A. Clinic has done 247ETs in women 44-45 using donor eggs or donor embryos.

126 out of these 247 embryo transfers resulted in live birth (51% Live Birth Rates)

We know exact term of delivery in 125 out of these 126 deliveries

  • 110 deliveries at term 37 weeks+ (88%)
  • 10 deliveries 33-36 weeks (8%)
  • 5 deliveries 32-28 weeks (4%)

▸ No deliveries before 28 weeks

▸ MR 16,5%
   11,9% before 12 weeks, 4,6% after 12 weeks

✔︎ Summary

After embryo transfers done at the age of 48-52. in O.L.G.A. Clinic Live Birth Rates were slightly lower than after embryo transfers at the age of 44-45 (47,4% vs 51%) , still very high in comparison to LBR after standard embryo transfer in Europe. The majority of deliveries in both groups took place at full term — after full 37 weeks (73,9% of deliveries in the 44-45y.o. group and 88% of deliveries in the 44-45y.o. group).

There were no deliveries before 28 full weeks in both groups.

✔︎ Conclusion

Live birth rates and obstetric outcomes are very good and comparable when using donor eggs in embryo transfers at the age of 48-52 and 44-45. Robust health check before undergoing embryo transfer in mature maternal age is crucial.

O.L.G.A. Clinic has established successful and safe process of fertility treatment and pregnancy support for women of advanced maternal age.

✔︎ Next Steps

Today, based on the contemporary state of the ART and our own results, O.L.G.A. Clinic is going to increase the age limit for fertility treatment in St. Petersburg!

From now on we will welcome women up to 53d birthday in St. Petersburg!
