Fertility Success Rates

A couples’ ability to conceive is affected by many factors – age, weight, male sperm count, reproductive history (the number of pregnancies, miscarriages, etc) and clinical diagnoses, are all factors that play a role in fertility and the success of fertility treatment. When it comes to choosing the right treatment for you, your fertility doctor is the ultimate source to counsel on the medical option most suitable for you to achieve success.

Below Aevitas success rates have been compared to benchmark statistics where possible, through the use of the ‘South African Registry for Assisted Reproductive Technology’ (SARA) 2014 report. The annual data of fifteen of South Africa’s top registered fertility clinics were used to compile the data for SARA.

Based on the statistics our Aevitas team is proud of our success rates!


Throughout 2013 – 2016 Aevitas Fertility Clinic has performed between 800 and 900 IVF cycles per year. ICSI has the same results as IVF, and therefore the pregnancy rate is often grouped together with that of IVF.

Benchmark success rate per IVF/ICSI treatment cycle is about 40%. In patients younger than 38/39 years, the pregnancy rate can be as high as approximately 50% per cycle.

Frozen Embryo Transfer (FET)

Patients who undergo IVF treatment usually choose to freeze (cryopreserve) an additional embryo for another IVF attempt, should their first cycle be unsuccessful, or should they continue to preserve it to expand their family at a later stage. This process is called frozen embryo transfer (FET).

Embryo cryopreservation (FET) has a benchmark success rate, over all age groups, of 31.9% per treatment cycle in patients under 38 years. Over all age groups Aevitas has achieved a higher than 40% success rate in 2015 – 2016.

Donor Egg Programme

Donor eggs are more likely used in IVF cycles if a female is older than 38, as the quality of eggs, and therefore fertility drops steeply in the late thirties/early forties.

Frozen (cryopreserved) or fresh donor eggs can be used in the donor egg programme. As the success rates of using frozen eggs during a donor egg cycle is improving rapidly, it is becoming an increasingly popular method to follow due to the simplification of the procedure this method allows.

Intrauterine Insemination (IUI)

Intrauterine insemination (IUI) is most commonly known as artificial insemination (AI). The placement of sperm into a woman’s uterus to facilitate fertilisation (IUI) is performed to increase the number of sperm that reach the fallopian tubes, to increase the chance of fertilisation. It is often used in low sperm count or decreased sperm mobility.

Aevitas Fertility Clinic is proud to be on par with IUI benchmark statistics. IUI benchmark success rate is 10% and up to 30% over 4-6 treatment cycles. IUI with donor sperm has a benchmark success rate of 10 – 15% and most patients will require 3-6 IUI cycles for successful conception.

Ovulation Induction

Ovulation induction, indicated for women who do not ovulate on their own regularly, could be due to various reasons and is addressed using fertility drugs.

Clomiphene citrate induces ovulation in about 80% of patients, and up to 40% are likely to conceive within 6 months of treatment.

Endoscopic Surgery and Advanced Endoscopy

Endoscopic surgery uses a scope through a small incision or natural body opening to diagnose and treat disease, such as endometriosis or the reversal of sterilisation (reanastomosis).

After endoscopic surgery for severe endometriosis, there is a 36% spontaneous pregnancy rate after one year. After reanastomosis of the fallopian tube(s) through endoscopic surgery, there is a 70% spontaneous pregnancy rate after one year.
