Fertility, IVF and Egg Donation
There are some in vitro fertilization clinics in the US that market aggressively for mini-IVF or micro IVF (also called mild or minimal stimulation in vitro fertilization). Some claims regarding the benefits of mini-IVF are exaggerated or completely untrue. This post clarifies some issues regarding standard vs. mini IVF.
Mild IVF (or micro, or mini IVF) seems to be slowly growing in popularity over the last few years. Is it a good fertility treatment?
- The basic concept is to do in vitro fertilization after a low level of ovarian stimulation with oral medications (possibly with some “low dose” injectables as well).
- This is in contrast to the usual method of ovarian stimulation for IVF which involves more aggressive stimulation of the ovaries with multiple injections over about 8 to 15 days.
- The standard method of stimulating is done in order to try to get about 10 or more eggs to work with for in vitro fertilization.
- The IVF cycle cost for mild IVF (including medications and everything) should be less than the total cost for standard in vitro fertilization
- However, the success rates for standard IVF are much higher
- Success rates with mild in vitro fertilization are much lower – often in the range of about 5% to 15% per attempt, depending greatly on the age of the female
Why do we try to get so many eggs for “standard” IVF?
IVF success rates are much higher with a “good” number of eggs due to the substantial drop-off that is seen in early embryo development.
The chart below shows the average number of eggs, mature eggs, fertilized embryos, “good” embryos on day 3, blastocyst embryos on day 5, etc. in three age groups of women at our clinic.
- If there are extra embryos available for freezing, we freeze on day 5 and day 6 (possible freezing shown by purple arrow going up).
As shown in the chart, in the average case there is progressive drop-off over time with in vitro fertilization. Human reproduction is not extremely efficient – if we were mice or cows we would be efficient reproducers. Alas, we are not so lucky – we are stuck being human…
- We expect drop-off in the eggs and embryos in the fertilization and development process
- Therefore, having more eggs at the beginning makes it more likely to have at least one embryo at the end that is strong enough to make a baby

In the United States it is very easy to investigate IVF success rates for all in vitro fertilization clinics
There are two websites that report IVF success rates annually to the public:
- CDC website (Centers for Disease Control and Prevention)
- CDC is a US government agency
- SART website (Society for Assisted Reproductive Technology)
- SART is an organization dedicated to the practice of IVF in the US
- Links to these sites that report IVF success rates
The CDC IVF Success Rate Report for 2008 report has not yet been released. In vitro fertilization statistics are currently available from the CDC for 1999 through 2007.
In late February 2010 the Society for Assisted Reproductive Technology (SART) released the IVF Success Rate Report for 2008 cycles.
The SART report is released every year on the web and is available to the public. Almost all reputable in vitro fertilization centers are members of SART. Members are required to submit their in vitro fertilization data annually. Each clinic has its own listing page that shows its success rates on the SART website.
To view any clinic’s success rates through SART:
- Go to the SART website
- Click on IVF Success Rate Reports
- On the map, click the state that you are interested in.
- A list of all reputable SART member clinics in that state comes up.
- Click on any individual clinic – a page called “Clinic Contact Information” appears. At the bottom click the link next to “ART Data Report”. You will go to a page showing that center’s in vitro fertilization success rates for 2008.
- To see the center’s IVF statistics from a previous year, use the pulldown menu at the upper left where it says “Select Year”.
Although clinics with low success rates don’t mention it, there are large differences in success rates between clinics
There are number of reasons for this, but the biggest difference between different clinics is the degree of quality control within the system.
Patients often ask me why our success rates are so high. The answer is simple. (continue reading…)
The Centers for Disease Control and Prevention, a US government agency, has just released a preliminary version of its 2007 Assisted Reproductive Technology (ART) Report. It expects to release the final version in December.
The Society for Assisted Reproductive Technology (SART) released its version of the report on 2007 IVF cycles several months ago. However, clinics are not required by law to report to SART. They are required to report to the CDC. Therefore, the CDC report shows success rates for more clinics than the SART report does.
The CDC report covers data from 430 fertility clinics. Over 142,000 assisted reproductive technology (or IVF) cycles were done at these “reporting clinics”.
There were (as always) some fertility clinics that broke federal law and refused to report their data. These IVF clinics are referred to as “non-reporting clinics”. If fertility doctors will go so far as to break federal law to keep their IVF outcome statistics from the public – those “non-reporting clinics” most likely have very low success rates.
Before you choose a fertility clinic for IVF – check success rates.
Couples with infertility often need IVF to get pregnant.What should they know about IVF clinic success rates?
- An interesting and unusual aspect of IVF is that there is a definitive outcome for each procedure.
- When an IVF cycle is done there is a baby born from it – or there is not. Therefore, keeping track of (and comparing) IVF live birth success rates is very straightforward.
- Medical treatments in general rarely have such “black and white” outcomes.
- Another unique aspect of IVF is that (in the US) all IVF clinics are required by federal law to report their in vitro fertilization success rates annually to the government. The CDC, a US government agency produces a report called the “Assisted Reproductive Technology (ART) Report” detailing IVF success rates for all individual clinics.
- This report is commonly called the CDC IVF success rate report. It is released to the public on the web every year (usually in December or January).
- Another useful report, the SART report (Society for Assisted Reproductive Technology), is very similar to the CDC report – and it is released about a year earlier. However, clinics are not required by law to report to SART – so some clinics are not listed there.
- These 2 annual reports allow consumers to view and compare IVF success rates for reputable fertility clinics.
