What are the chances of success?
First, note that in the absence of fertility treatments fertile couples have a 20-25% chance of achieving a lasting pregnancy in any one month cycle. This means that about one out of every four or five fertile couples "succeeds" each month. For infertile couples the use of assisted reproductive techniques, such as IVF, can increase the chance of producing a pregnancy and having a baby from any one treatment attempt.
A couple's chance of success with assisted reproduction is linked not only to the conditions and the abilities of their IVF clinic, but also to the specific infertility causes and the woman's age. Overall statistics for any given clinic reflects the rate of pregnancy for all couples who have undergone treatment at that clinic, including those with especially limited prognoses, advanced age, or minimal sperm quality. Many couples, especially younger couples, will have a much higher chance of pregnancy than the overall statistics.
The worldwide experience of IVF indicates that the chance of a live birth resulting from a single attempt is in the range of 15-28%. In other words, one to three couples out of a group of ten attempting one treatment cycle will be rewarded with a birth of an infant. However, these statistics include programs with a variety of methods and techniques.
Our program is dedicated to providing individualized treatment to couples.
We have been successful in consistently achieving and maintaining outstanding
pregnancy rates. A reasonable assessment of the likelihood of pregnancy
following a single attempt at IVF would indicate a pregnancy rate of approximately
28%-42% for women age 39 or younger for Day 3 embryos, and up to
60% following the transfer of blastocysts (Day 5 or 6).
Note: National statistics for each year are collected in the December of
the following year - allowing time, at least nine months, for all outcomes
to be reported. The results are published in the year after; thus the figures
for year 2003 will be available in 2005.
