Everything You Need to Know About The IVF Success Rate

IVF success statistics are intended to help you determine the chances of bringing home a child. There is a straightforward explanation for why there are disparities in IVF success rates: to put it simply, success rates vary.

How are success rates for IVF depicted?

If you visit the website of a particular facility, you will likely find a page describing their unique success rates. Typically, they are shown in a bar chart format and contain various information based on patient age and, sometimes, therapy or cycle type. The graph should indicate the time frame from which the data was collected.

All IVF/fertility clinics in Australia must comply with stringent rules to guarantee that you are supplied with accurate and easily understandable information. The Australian Health Practitioner Regulation Agency (AHPRA) and the Reproductive Technology Accreditation Committee (RTAC) establish and oversee the guidelines . The guiding principles seek to guarantee that success rates are presented in a manner that enables the public to make an educated decision about their healthcare and reproductive treatment.

It is essential for each clinic to properly display the information included in their success rates, such as the age of the women and the kind of therapy administered. You may get success rates on the websites of the majority of clinics, as well as through industry efforts and organisations such as the Australia New Zealand Assisted Reproductive Database (ANZARD).

What variables affect the success of bringing life into the world through in vitro fertilisation? There is a great deal of contradictory information available on IVF treatment success rates. Simply stated, success rates rely on a variety of variables, such as the quality of the clinic, the age of the patient, the sorts of treatments offered, and whether the statistic is based on clinical pregnancies or live births.

A clinical pregnancy is one that meets at least one of the following conditions:

  • Known to be continuing at 20 weeks
  • Ultrasound evidence of an intrauterine sac (with or without foetal heart)
  • A study of miscarriage products reveals placental tissue
  • An ectopic pregnancy has been identified by laparoscopy or ultrasound
  • A live birth occurs

Clinic

Each IVF facility exhibits distinct success rates. The differences across clinics are mostly attributable to the types of patients they serve, as well as the atmosphere of the lab and the expertise and experience of the personnel, including embryologists and fertility experts. The underlying reason for infertility and the clinic’s therapy should also be considered. Ask if the unit has a protocol to transfer the best embryo in a fresh embryo or frozen embryo cycle, as well as whether they advocate genetic testing (PGS) for all patients.

The sorts of patients a clinic accepts may have an impact on its overall success rate. Some routes to conception are more challenging than others, and not all clinics accept complicated cases. Due to a shortage of resources or a desire to maintain high success rates, the unfortunate fact is that many clinics only accept patients with a high likelihood of obtaining pregnancy. Other clinics with superior research are more likely to treat all patients, even those who may have been unsuccessful elsewhere or who need more assistance with donor gametes or genetic testing.

Age

When examining a clinic’s success rates, a variety of age groups are often included. As with spontaneous conception, the probability of obtaining a pregnancy using IVF (or any other sort of reproductive therapy) falls as the mother’s age increases.

Currently, the success rate for individuals under 30 is almost four times that of patients over 40, although the most recent study indicates that all age groups enjoy a rise in pregnancy rates in consecutive cycles.

Contrast clinical pregnancy and delivery

Most IVF clinics display their success rates in two columns, one for clinical pregnancies and the other for live deliveries. Due to the chance of miscarriage, the number of live births will always be lower in whichever clinic you examine.

Type of Therapies

This may contribute to the variation in success rates across clinics. For instance, some clinics display success percentages for blastocyst transfers, in which the embryo is returned to the uterus around day 5 after fertilisation. Prior to studies demonstrating that blastocyst transfers were the most efficient kind of transfer, the majority of clinics employed a procedure known as cleavage stage transfer, which happens on day 2 or 3. Currently, some clinics report success rates based on just one of these two methods, while others continue to report both.

No matter what form of therapy or transfer the success rates pertain to, it must always be specified on the graph or page containing the success rates.

Realising your likelihood of success

data

It is vital to remember that a clinic’s general success rate may or may not relate to you and your treatment requirements while evaluating their success rates. It is also crucial to realise that the pregnancy and birth rates of people over 35 who undergo normal IVF therapy might decline dramatically.

Your Fertility Specialist will advise you on your individual treatment choices and discuss your likelihood of success, taking into account your type of infertility, your age, and the therapy you are receiving. Assisted Reproductive Treatment (ART) methods and their accompanying success rates have advanced fast since their inception, although generalised success statistics may be deceptive owing to the uniqueness of each patient’s condition. There are numerous obstacles to overcome throughout treatment, and it is essential to remember that they must all be overcome in order to have a successful pregnancy.

Ask as many questions as necessary to your Fertility Specialist, nurse, and counsellor about these obstacles and your individual therapy. It is preferable to be well-prepared than to have to cope with unanticipated circumstances at this significant and often challenging period of life.

Numerous variables may influence success rates, including:

  • Genetic variables
  • Fertility background
  • The age of the female companion
  • Lifestyle variables such as weight and smoking
  • Contributing factors to infertility
  • Quantity and quality of eggs retrieved
  • Evaluation of sperm (including motility and ability to penetrate the egg)
  • Laboratory processes
  • Expertise and proficiency of the treatment team

Despite the fact that ART provides useful possibilities for the treatment of infertility, the decision to utilise ART depends on a number of criteria in addition to success rates. Repeated ART cycles need significant investments of time, effort, money, and emotional energy. Before initiating therapy, you should thoroughly consider all associated financial, psychological, and physiological difficulties. You may also want to evaluate the clinic’s location, the accessible counselling and support services, and the staff’s interaction with patients.
