Will your treatment be successful?

The team at Waterstone Clinic has consistently delivered world class success rates over the past decade. This track record has been achieved through attention to detail in laboratory and clinical practice, in order to achieve the best possible outcome for each patient.

For patients undergoing IVF, there is one question that overshadows all others; “What is my/our chance of becoming pregnant and having a baby?”

Success rates will be influenced by many factors, some of which are listed below. We can however, estimate your chance of success based on your age and fertility history. The age of the female partner is perhaps the single most important factor affecting a couple’s chances of success with IVF. The probability of having a child declines after age 35 and falls significantly beyond 41, while miscarriage rates increase with age. 

The figures below will help you estimate your chance of pregnancy
under our care based on 6 years results for the period 2010-2016

I am 37 years or younger, what are my chances of pregnancy from blastocyst
transfer following IVF/ICSI treatment at Waterstone Clinic?

The likelihood of conceiving.

The likelihood of having a fetal heart beat on ultrasound at 8 weeks of pregnancy.

I am 38 years or older, what are my chances of pregnancy from blastocyst
transfer following IVF/ICSI treatment at Waterstone Clinic?

The likelihood of conceiving.

The likelihood of having a fetal heart beat on ultrasound at 8 weeks of pregnancy.

There are, however, many hurdles to overcome during treatment and it is wise to keep in mind that they all have to be successfully navigated to get to what we are all striving for – a baby to take home. The key message is to seek help from specialists early and not to delay treatment where it is advised.

How Do We Compare?

Irish clinics, unlike UK clinics, are not obliged to officially publish their success rates. This can mislead patients. A snapshot of a very specific and successful patient group may not relate well to the average patient. Often, clinics will reveal their success rates for positive tests or clinical pregnancies achieved but we feel that a live birth is the ultimate measure of success.

In the UK, publishing accurate and clear success rates is mandatory. Therefore, we consider the most transparent way to communicate our success rates to you the patient, is to compare ourselves to the top 10 UK clinics.

As you can see, our live birth rates speak for themselves;

Live Birth Rate Per Embryo Transfer

  • Waterstone Clinic Live Birth Rate (2010-2016)
  • Top 10 UK Clinics Live Birth Rate Average (2012-2015)

While we are very proud of these results, we feel nothing speaks higher for us than our patient success stories. You can view our success stories by clicking here

Clinical Pregnancy Rates eSET cycles

In keeping with best international practice, we introduced an eSET (elective single embryo transfer) programme in order to reduce the incidence of twins; only one embryo is transferred in the fresh cycle and the remainder frozen for future use.

Below we share our rates for the period 2010-2016 for all eSet cycles. Our results show that when pregnancies from frozen embryo transfers are included 93% of patients will have conceived and 73% will have a clinical pregnancy after their first eSET cycle.

Importantly these figures are based on the presence of fetal heart activity at 8 week’s gestation (when the risk of miscarriage is less than 5%), most other fertility clinics clinical pregnancy rates are based on the presence of a pregnancy sac only that may not carry a live fetus.

Factors affecting chance of success

Success rates can be affected by many factors, including:

  • Genetic factors
  • Fertility history
  • Age of the female partner
  • Lifestyle factors including weight and smoking
  • Conditions contributing to infertility
  • Quality of eggs and number of eggs recovered
  • Quality of sperm (including motility and ability to penetrate the egg)

Comparing Statistics

It is important to understand the data presented when comparing ‘success rates’ between clinics. Often pregnancy rates can be quoted and these will always be higher than live birth rates. A clinic’s success rate may also be influenced by its policies for cancelling cycles and by the number of embryos transferred.

Because live births can be calculated as a percentage of cycles started, egg collections or embryo transfers, it is very important to compare like with like when reviewing results. For example, the percentage of live births per egg collection is lower than the percentage of live births per embryo transfer. There are less egg collections than cycles started because some cycles are cancelled before egg collection.
