Age has been shown to be the only robust factor in predicting the success of IVF treatment. The likelihood of becoming pregnant declines as couples age, but the average age of women seeking fertility treatment has steadily increased over the last 20 years, reflecting the trend for couples to start families later on.

When an IVF cycle fails, many people feel grief, anger and frustration. It’s extremely normal to feel these emotions, but you should not blame yourself or your partner. IVF can fail for many reasons.

The following factors are considered when calculating your odds:

  • Age
  • Height and weight
  • Number of previous full-term births
  • Total number of pregnancies (including pregnancy losses)
  • Whether you plan to use your own eggs or donor eggs
  • Your cause for infertility (if known)

Here are some common reasons why an IVF cycle fails.

Embryo Quality

The major reason why an IVF cycle is not successful is embryo quality. Many embryos are not able to implant after transfer to the uterus because they are flawed in some way. Even embryos that look good in the lab may have defects that cause them to die instead of growing. In nearly all cases, it’s not that your uterus has something wrong with it so you can’t carry a baby. The embryo doesn’t implant because it is not healthy enough to grow.

The Age of the Eggs

Whilst the age of the woman undergoing IVF plays a huge part, the age of the eggs is more important. As a woman grows older, the quality and quantity of a woman’s eggs begin to worsen. This will greatly affect her chances of pregnancy with and without IVF. On average, around 25% of embryos used in IVF will result in a live birth. At Nurture Fertility, our success rates are 39% for women under 38 and 17% for those over.

Older women are more likely to have a greater chance of IVF success when using donor eggs.

Ovarian Response

Sometimes a woman’s ovaries don’t respond to the harmful hormonal fertility medications enough to produce multiple eggs. Especially if a woman is over 37 or has higher FSH levels she may not produce enough eggs to result in a number of embryos for screening and potential implantation. Chances are higher that IVF will fail when this happens. Your reproductive endocrinologist will evaluate what happened and may make changes to your fertility medications for the next IVF cycle.

Chromosomal Issues

One of the major factors in IVF failure is chromosomal abnormalities in the embryo. This is true for all human embryos, whether naturally conceived or developed in the embryology lab. These abnormalities are the reason behind most miscarriages as well as failure to implant in an IVF cycle. Studies have shown that starting in their 30s, as women age, the incidence of choromosomal abnormalities in their eggs begins to increase. By the mid-40s as much as 75 percent of a woman’s eggs have chromosomal abnormalities. A man’s sperm develops more chromosomal abnormalities as he ages as well, but at a much lower rate than a woman’s eggs. It’s unfair, ladies, but it’s true.


You will probably be asked to quit smoking up to three months before the start of your IVF treatment. Smokers often need up to twice as many IVF cycles to conceive and are more likely to experience a miscarriage. If you are overweight or underweight, you should try and reach a healthy weight to increase chances of a successful IVF treatment.
