2023 Success Rate with Donor Eggs Exceeds 80%

Success rates

Donor Eggs Australia commenced 21 years ago and our pregnancy success rate began at 65%, rising to 72% by 2016 and now exceeds 80%.

Our excellent success rates are achieved for many reasons, some of which are highlighted below.

  • Selection of young donors, the majority being under or around 30 years of age
  • Careful preparation and stimulation of these donors by our highly professional associated clinics, with our input. Our aim is egg quality and NOT egg quantity!
  • The careful and comprehensive preparation of our recipients in terms of their general health, with physician check-ups, reproductive health and careful evaluation of the uterine cavity, and personalised monitoring of their endometrial preparation prior to embryo transfer
  • >We have a dedicated team working only on donor egg cycles, and we do not form part of any busy IVF clinic. Our donor egg patients are our sole focus
  • Our team’s aim is to assist and make this journey as smooth and stress free as possible. We are fully aware of what our patients have previously gone through before seeking donor eggs

Understanding Success Rates 

Donor Egg Success Rate Statistics


The success rates for fertility treatment using IVF technology is one area that abounds in over exaggeration and misunderstanding.

Part of the problem is that 2 different statistics can be quoted

  • Pregnancy rate
    This, is defined as the presence of a foetus with foetal heart usually diagnosed on transvaginal ultrasound early in the first trimester ± 6-7 weeks.
  • Live birth rate
    This accurately describes the live birth rate.

In view of the fact that our patients have been expertly evaluated prior to embarking on oocyte donation, the major factors affecting outcome are predominantly:

  • Age of the egg donor
  • Sperm quality
  • Number of embryos transferred
  • Endometrial Preparation of the Recipient

Our current pregnancy rate is now averaging 80% with a live birth rate of 70%, and a twin live birth rate (non-identical) is 9.2%.

Many patients elect to have 2 embryos transferred, even after being counselled about the risks and complications.

How many embryos should be transferred?

Under ideal circumstances the preferred option is ONE embryo!

If you decide to transfer more than one embryo you run the risk of multiple pregnancy and the increased maternal and foetal risks associated with twins, so that when 2 embryos are transferred the risk of a multiple pregnancy is 10% (twins). Transferring more than 2 embryos is not advised and will depend upon the individual overseas clinics restrictions.

Risk of twins compared with singleton pregnancy
Obstetric complication Risk
Anaemia x2
Pre-eclampsia x3
Eclampsia x4
Antepartum haemorrhage x2
Postpartum haemorrhage x2
Fetal growth restriction x3
Preterm delivery x6
Caesarean section x2


% of Preterm Deliveries vs Number of Foetuses
Number of foetuses < 28 weeks < 37 weeks
Singleton 0.7% 6.2%
Twins 4.4% 52.1%
Triplets 21.8% 98.2%

Our patients are counselled about the risks of multiple pregnancy and the need to minimise prematurity. Despite this advice to attempt a single pregnancy, our patients often elect to transfer more than one embryo because they are often older, are having to travel overseas and are wanting to achieve the highest pregnancy rate in the shortest possible time.
