Chance for Pregnancy with and without Clear Passage®
There is no substitute for published facts.
If you are serious about reversing your infertility, there is no substitute for reliable data published in peer-reviewed medical journals. The studies cited in these pages are indexed in PubMed, the ‘gold standard’ search engine maintained by the U.S. National Institutes of Health (NIH).
Additional data comes from the U.S. Centers for Disease Control (CDC) database of success rates for U.S. reproductive clinics. To allow time for live births and data collection, the CDC report shows results of procedures performed 2 to 3 years prior.

Advantages of IVF
- Physician monitored
- Whether success or failure, results occur quickly
- Additional eggs may be saved for future transfers
Disadvantages of IVF
- If unsuccessful, attempt must be repeated
- Must be repeated for every desired pregnancy
- May involve surgery to remove one or both fallopian tubes
- Involves pharmaceutical medications some may wish to avoid
- Not shown to improve intercourse pain or sexual function
Worldwide IVF Success Rates
-
United States: 24.11%[iv]
-
United Kingdom: 2% to 29%[v]
-
Japan: ~ 5%[vi]
-
Australia / New Zealand ~10% to 15%[vi]
Several studies examine worldwide success rates for IVF. Most note a significant decline in pregnancy rates over the last 10 – 12 years[vii] as shown below.
United States IVF rates:
In vitro fertilization (IVF) is often suggested for women with blocked fallopian tubes. Based on CDC’s 2018 Fertility Clinic Success Rates Report, the 306,197 ART cycles performed at 456 reporting clinics in the United States during 2018 resulted in 73,831 live births. Based on the above, CDC shows a 24.11% national success rate for Assisted Reproductive Techniques in the USA, 99% of which are IVF. Some cycles were designed for ‘egg harvesting’ with the intent of using those eggs in later transfers which makes more exact results difficult to tabulate. Thus, we made further inquiry with results shown below.
Worldwide and US Downward Trend in IVF Success:
A 2019 study[viii] of two decades of IVF pregnancy rates showed a downward trend in worldwide and US IVF pregnancy rates starting in 2010. The study notes that US live birth rates for fresh cycle IVF or ICSI reached a high in 2008, plateaued till 2010 and have since steadily declined with profound drops between 2013 and 2016, the last year cited in the study.
United Kingdom IVF Rates: 2% to 29%
The British National Health Service (NHS) reports[ix] that between 2014 and 2016 the percentage of IVF treatments that resulted in a live birth was:
- 29% for women under 35
- 23% for women aged 35 to 37
- 15% for women aged 38 to 39
- 9% for women aged 40 to 42
- 3% for women aged 43 to 44
- 2% for women aged over 44
Other countries
IVF rates in Japan and in (combined) Australia and New Zealand cited in the study were:
-
Japan: ~ 5%[x]
-
Australia / New Zealand: 10%-15%vi
Surgical Success Rates
While surgical success rates vary widely, performing surgery on structures as tiny and delicate as fallopian tubes can be challenging for physicians. Because adhesions form after 55% to 100% of pelvic surgeries[xi], most surgeons feel that surgical tubal repair provides a brief window of time to conceive before new adhesions form and re-block the repaired tubes. This rapid re-closure does not appear to happen after Clear Passage®️ therapy, perhaps due to the absence of post-surgical adhesions; many of our successes have gone on to have additional full-term pregnancies for several years after this physical therapy opened their tube(s).
