For single women 35-39

Are you a healthy single woman between the ages of 35-39?

If you are 35-39, please be prepared to receive news that more than half of eggs produces by you are already not healthy (=abnormal) due to egg aging process.

The Egg aging process starts after 30 and results in chromosome abnormality in more and more eggs, which makes them incapable of creating a healthy ongoing pregnancy and or a healthy child 

In women

  • 20-25% eggs are already abnormal in the age of 30
  • 40-45% of eggs are abnormal in the age of 35
  • 70-75% of abnormal eggs in the age of 40

Waiting for ‘Mr Right’ may become too risky due to this egg aging progress!  Hence this may be a good reason for you not to wait any longer and to proceed towards creating your own child, with your own eggs, before the majority of the eggs become abnormal after the age of 40 and almost all after the age of 42 [D. Wells, 2013]. Luckily there is a genetic method to help sort out the abnormal eggs and embryos and to create a pregnancy with a healthy child. Interested? Read more!

So if you have decided that you do not want to wait any longer and instead experience the wonders of motherhood for yourself we can help you achieve your dreams.

If you are single it may still be challenging to create your own child due to multiple reasons: legal restrictions in your own country not allowing fertility treatment for single women or a compromise called “sperm donation” which you may not even want to think about…

We believe that your own baby created with you own eggs is the best gift a woman may ever receive in life. So we would rather recommend that you do not wait any longer and to proceed with your own eggs and donor sperm, rather than to wait for the right prince charming for several more years and to end up creating a child with his sperm but … donor eggs



Sperm donors

At O.L.G.A. Fertility Clinic we are proud to be able to offer you a donor with a basic profile from our own sperm donor database. Within the basic profile you will receive the following information about a sperm donor: age, blood group, height, weight, eye and hair colour. However you would prefer to use an open sperm donor, choose your own donor and gain in-depth information and profiles of the donor we are more than happy to recommend European Sperm Bank and help you with the choice and sperm transportation to our clinic.

If you would like to find out more about different sperm donor options and how we can use this to meet your own personal needs please contact us for a free non-obliging telephone consultation.

Which treatment options come in question for you if you are a healthy single woman between the age of 36-39?

Treatment opportunities


  If your fallopian tubes are open and ovarian reserve is good we recommend you to consider Insemination with donor sperm.

Artificial intra-uterine insemination (IUI) is a procedure for transferring sperm cells into the uterine cavity. Before being transferred into the uterus the sperm is thoroughly prepared: washed, centrifuged, the quickest and hence the most promising sperm group separated. Insemination although simple, is still a highly effective method of assisted reproductive techniques (ART)

If you would like to find out more information or advice about Insemination with donor sperm and how we can use this to meet your own personal needs please contact us for a free non obliging telephone consultation.

If your fallopian tubes are blocked, or 3-4 IUIs with donor sperm have not helped to achieve pregnancy, we recommend to consider IVF with your own eggs and donor sperm + genetic testing of your embryos before embryo transfer

The IVF (in vitro fertilization) is a procedure of fertilizing your eggs outside your body (in a test tube) and transferring your embryo inside your uterus in the right time and place. IVF allows not only to make sure that fertilization of an egg with a sperm has taken place and a developing embryo is placed at the right time, in the right place, but also provides access to embryos at pre-implantation stage! This provides you with a unique opportunity of genetic testing of your embryos so that only these 45-55% of your embryos, which are normal can be transferred in the uterus, not the wrong ones. Genetic screening of your embryos before embryo transfer in the uterus increases efficiency of your embryo transfer and reduces time to pregnancy!

If you would like to find out more about how your eggs are grown and collected as well as how an embryo can be genetically checked and then put back in the uterus, please read more here:

If you have certain medical condition such as fallopian tube dysfunction/previous removal, endometriosis, fibroids, reduced follicular reserve (low AMH) or even premature menopause, please do request a free of charge non-obliging phone consultation with our doctor so that we advise your options and help you choose the best strategy to meet your physical needs and personal values.

For example women with endometriosis to use rather IVF then IUI  if they are already in the age of 35 and more.

Women in premature menopause have sadly no eggs left independent of their age. Luckily it is still possible to become a mother through IVF with donor eggs and donor sperm

“…I am a single woman and when one is lonely, one is very sensitive…You saw me as a person and I felt that you can help me…”



“…Well the Millennium shift came, the year 2000, we all remember what we did then, right? I got cancer, Hodgkin's lymphoma... And when I stand here now 17 years later, you understand that it went well! Except for one important thing…"


“…When I left the clinic and walked down the Nevsky Prospect I knew I was pregnant — and the feeling was right! 9 month after her visit at the AVA Clinic Alexander was born!”
