This IVF success estimator does not provide diagnosis, medical advice, or treatment.

These estimates may not reflect your actual rates of success during ART treatment and are only being provided for informational purposes. Estimates are less reliable at certain ranges/values of age, weight, height, and previous pregnancy and ART experiences.

See your doctor and/or healthcare provider for a personalized treatment plan that is best for you.

IVF Success Rate Calculator (Estimator)

IVF success rate estimator allows you to determine the approximate probability of having a baby after one or several cycles of treatment with methods of assisted reproduction in each case.

Based on statistical outcomes gathered from fertility clinics all over the USA annually, specialists have developed an algorithm that makes it possible to fairly realistically assess the chances of conception.

To obtain the result of the expected probability of having a baby after the IVF cycle treatment, you will need to go through 6 simple questions about your body parameters, health condition and method of conception, in each of which you will need to choose or write an answer.

The success rate of IVF treatment cycles depends on so much more than just the experience of fertility doctors and clinical techniques, actually more important factors that must be considered to predict the rate favorable outcome are The reasons and duration of infertility, response of ovaries to stimulation, the number and quality of eggs matured in follicles, the quality of sperm and so on.

Some non-modifiable factors largely determine the prognosis of IVF treatment cycles, like:

  • Maternal age

Specialists claim age to be one of the main factors determining the success of the IVF procedure. As females get older their reproductive capacity naturally significantly declines, which makes it harder for them to conceive and is also often associated with higher rates of pregnancy complications.

Fertility in women after 35 years decreases irreversibly, So, the probability of having a child by a woman younger than 31 years old (at the time of the first IVF cycle) is much higher than after 37 years.

  • Maternal Weight
  • Maternal height

Multiple studies state that maternal BMI has a significant influence on successful pregnancy, extremes of BMI raise the risk of preterm birth and unsuccessful IVF treatment cycles

  • How many times have you used IVF in the past (all cycles included, even those not resulting in pregnancy)
  • Number of prior Pregnancies
  • Number of prior Births

If pregnancy did not occur in the first attempt, this does not mean that a successful cycle is impossible to achieve in the future. To date, experts have concluded that it is fair to speak about unsuccessful treatment only after the third unsuccessful attempt at ART.

The number of previous attempts has a prognostic factor for the next successful IVF cycle. In other words, if the previous IVF  was successful there is a greater chance to achieve the same result again.

  • Diagnosis

Here you choose the exact cause of your infertility in case you know, which can be:


  • Endometriosis – a disorder where tissue that normally lines the uterine cavity grows elsewhere in the body and creates problems with fertility
  • Uterine factor – any anatomical uterine anomalies like fibroids or scars
  • Fallopian tube factors – damaged fallopian tubes prevent eggs to travel from ovaries to the uterus
  • Ovulatory disorder (including PCOS) – hormonal disorders that diminish the function of ovaries
  • Diminished ovarian reserve – which is naturally declined with age

Paternal :

Any male factor infertility like

Low sperm count

Abnormal sperm function

Blockage of sperm delivery and so on.

Unexplained (Idiopathic) Infertility :

In couple who were evaluated for complete infertility screen, despite normal results are still unable to conceive

Other reasons:

Recurrent pregnancy loss

Some medical contraindication to pregnancy

Use of a gestational carrier


Knowing the diagnosis helps fertility doctors estimate favorable outcomes for IVF cycles since different disorders have distinct management methods and individual prognostic factors that affect rates for successful conception differently.

  • Egg source

Own eggs or Donor eggs

If an infertile woman has exhausted her ovulatory reserve, then she may be offered donor help. This refers to the use of someone else’s eggs for artificial insemination. At a later age, fresh or frozen eggs from a donor are used for this procedure, instead of own eggs.

After filling in all the questions, the user will see a chart and the probability of conception as a percentage after the first, second and third additional full IVF cycle. Besides that, you will be able to find the second group of charts comparing the probability of success according to the number of embryos transferred.

Transferring large amounts of embryos not only increases the rate of success for IVF cycles but also the probability of multiple gestations, which itself increases the risk of pregnancy complications.

The researchers emphasize that the calculator gives only an estimated forecast, and it is not worth considering it as the ultimate guarantee, since life makes its adjustments and every conception process is very individual. So make sure to consult your doctor to further analyze the calculation results.
