Success Rates

We are committed to conducting and publishing clinical research. Only scientific observation, testing, and measurement can yield meaningful results, in any modality.

Following is an overview of our published and pilot study highlights and success rates. These are divided into various categories to make them easier to read. Footnote references following each statement give the study reference for that fact.

Natural fertility success rates

71% natural pregnancy rate within one year of receiving therapy ¹
Note : Ongoing success rates with natural fertility reversal can be difficult to determine due to follow-up, 12 and 24 months after therapy. Judging from success rates we can easily measure (e.g. opening blocked fallopian tubes, IVF pregnancies after therapy) we believe our natural fertility success rate is between 60% and 65%.

Pre-IVF success rates

67% IVF clinical pregnancy rate for women who received therapy within 15 months of IVF transfer ¹

Duration of infertility

• women in the above studies (natural and pre-IVF) were infertile for an average of five years prior to therapy ¹
• longest duration of infertility successfully treated (natural pregnancy/birth) is 12 years ¹

Live birth rates

• 90% of women who became pregnant in the natural fertility study delivered full-term babies ¹
• 33% of these women had a subsequent pregnancy and live birth, suggesting that this treatment may have lasting effects for some women ¹
• 79% of women who became pregnant in the pre-IVF study had live births ¹

Blocked fallopian tubes

• 61% success rate opening blocked fallopian tubes ²,⁸
• 53% natural intrauterine pregnancy rate for the patent patients ²,⁸
• 66% patency (one or both tubes open) rate for patients with proximal blockage ²
• 50% patency rate for patients with distal blockage ²
• 40% patency rate for patients with mid-tubal blockage ²
• 80% patency rate for patients with combination blockage ²

Hydrosalpinx

• 50% (4/8 patients) success rate opening tubes blocked with hydrosalpinx ³
• 50% (2/4 patent patients) had a natural post-therapy full-term pregnancy via the tube previously blocked with hydrosalpinx ³

Advanced age

• 60% natural pregnancy and live birth rate for women 35 or older in the natural study ¹
• 57% IVF clinical pregnancy rate among women 41 or older in the pre-IVF study ¹
• a 43 year-old pre-IVF study participant had four unsuccessful pre-treatment IVFs, then became pregnant and had a live birth with her first post-treatment IVF ¹
• a 36 year-old pre-IVF study participant had three unsuccessful pre-treatment IVFs and one post-treatment, then became pregnant naturally after therapy and delivered a healthy baby girl ¹
• a 42 year-old blocked tubes study participant had never been pregnant and had two blocked tubes for 10 years; she became pregnant naturally after therapy and delivered a healthy baby girl ²
• the oldest natural infertility reversal reported to us was 43 years old when she gave birth 
• the oldest IVF success reported to us (using her own fresh eggs) was 48 years old when she gave birth to twins

Women with prior unsuccessful IVFs

• 71% clinical IVF pregnancy rate for patients who had failed to become pregnant in two or more pre-treatment IVF transfers ⁴
• 57% live birth rate for the above patients ⁴
• clinical pregnancy and live birth rates in this group include a 43 year old patient ⁴

Sexual function and pain level improvements (general)

• 93% of women in the natural fertility study reported decreased pain ¹
• 96% of sexual function study participants reported reduced sexual intercourse pain ⁵
• 56% had improved or first-time orgasms ⁵
• 65% had increased satisfaction ⁵
• 70% had increased lubrication ⁵
• 74% had increases in their arousal ⁵
• 78% had greater or renewed desire (libido) ⁵
• 91% had overall increased sexual function ⁵

Sexual function and pain level improvements (endometriosis)

• 50% of study participants reported reduced ovulation pain ⁶
• 61% of study participants reported reduced menstrual pain ⁶
• 93% of study participants reported reduced intercourse pain ⁷
• 64% reported increased intensity and duration of orgasm ⁷
• 71% reported increased desire (libido) ⁷
• 86% reported increased arousal ⁷
• 79% reported increased lubrication ⁷
• 71% reported increased satisfaction ⁷
• 93% reported improved overall sexual function ⁷

Improving hormone levels

Over 80% of women with high FSH before treatment, reported a natural pregnancy or significant decrease in FSH levels after treatment (clinical trials)
