Overview
This page covers Mercier Therapy, a hands-on abdominal and pelvic method linked to the midwife Jennifer Mercier and used mainly in the context of female infertility. It sets out the little that independent sources document about its origin, practice and training, and it reports what trials and reviews of related manual methods found. It also states plainly what the sources reviewed do not cover.
Where does Mercier Therapy come from?
Earliest dated record
Mercier Therapy is named for Jennifer Mercier. The earliest dated record found is a short note titled Merciér Therapy Helps Infertile Women Achieve Pregnancy, written by Mercier and Karen Miller and printed in Midwifery Today, issue 105 (2013, pages 40 and 68). PubMed gives Mercier's affiliation as Sparks Women's Center and Sparks Hospital in Fort Smith, Arkansas, and the magazine page summarizes the piece as describing a therapy involving abdominal and pelvic work.
The founder's own account
The magazine's author notes describe Mercier as a reproductive health specialist, women's wellness practitioner and midwife in practice since 1999. They say she has severe endometriosis and that she gave birth to her first child in October 2011 after her students used the therapy on her. This is a personal account in a biography and is not a measured outcome. The pages opened for this article do not say when or how the method was developed, or where it was first taught.
Relationship to other manual methods
None of the sources reviewed traces Mercier Therapy to a named earlier school, so any link to other methods is unestablished. Systematic reviews describe visceral manipulation as a family of techniques common in osteopathic practice and taught in workshops to health professionals, including physical therapists. A separate branded manual pelvic method, studied by Wurn and colleagues for tubal blockage and infertility, has its own protocol and should not be treated as the same method.
What do the names and terms mean?
Name and spelling
The term is a proper name for a method associated with one developer, not a general clinical category. The 2013 magazine title spells it with an accent as Merciér Therapy, and no alternative names for the method were found in the sources opened. The article summary uses the phrase abdominal and pelvic work, which is the creator's and colleague's own wording and not a standardized clinical term.
Terms for related techniques
Reviews use several labels for hands-on work on the organs and their surrounding tissue, including visceral manipulation, visceral osteopathy and fascial therapy targeting the visceral system. One review describes such work as light or deep manual fascial releases and specific organ mobilizations in the thoracic, subdiaphragmatic, abdominal and pelvic areas. No source reviewed states that Mercier Therapy belongs to this group, and similar wording should not be read as showing the methods are equivalent.
What does Mercier Therapy involve?
What the sources document
The full text of the 2013 note is restricted to members of the magazine and was not read. As a result, the sources opened do not verify how a session is conducted, how long it lasts, how many sessions are usual, what pressure is used, or what a person is asked to wear or do. The note's second author is described as a licensed massage therapist at a hospital-linked women's center who is certified in the method, which indicates at least one setting in which it has been offered.
Formats used for comparable methods
For context only, the Clear Passage studies used a series of about 20 hours of manual treatment delivered over roughly one week, in which therapists reached deeper structures indirectly by working on the peritoneum and on the uterine and ovarian ligaments. Trials of visceral techniques in other conditions used between one and 20 sessions. These are protocols for other methods and do not describe a Mercier Therapy schedule.
What is Mercier Therapy used for?
Uses stated in the sources
The one use stated in the sources opened is support for women with infertility: the 2013 note is summarized as describing the therapy's success with previously infertile women. The founder's biography also links the method to her own endometriosis. Other uses attributed to the therapy in practitioner materials could not be checked against a source that could be opened, so they are not listed here.
What guidance says about non-medical approaches
The European Society of Human Reproduction and Embryology (ESHRE) 2022 endometriosis guideline concludes that no recommendation can be made for any specific non-medical intervention for pain, or to increase fertility, and names acupuncture and physiotherapy in those lists. Manual therapy and massage are not discussed, and the guideline does not mention Mercier Therapy. Its graded recommendations on infertility concern surgery and assisted reproduction.
What does the research show?
Searches and results for Mercier Therapy
On 11 October 2026, PubMed was searched for Mercier Therapy and for Mercier with infertility, endometriosis and pelvic terms. The only relevant indexed item was the 2013 magazine note, which has no abstract. No trial, case series or review of Mercier Therapy was found, and no outcome data for it were verified. Other databases were not searched.
Studies of a related manual pelvic method
A 2004 report of 53 infertile women treated with a different manual method described 14 of 17 women seeking natural conception as followed up, with 10 pregnant within a year, and 22 clinical pregnancies in 33 embryo transfers in women planning IVF against 12.7 expected from national figures. A 2008 retrospective series of 28 women with blocked tubes found 17 with an open tube afterward. Both were uncontrolled, were published by the treating clinic's team, and were read as abstracts only.
Reviews of visceral techniques and endometriosis care
A 2018 systematic review judged diagnostic techniques in visceral osteopathy unreliable and found that the least biased of six efficacy studies showed no significant difference. A 2023 review of 11 randomized trials with 490 participants rated six at high risk of bias and judged the evidence poor; none tested fertility outcomes. A 2026 review of physical therapy for endometriosis symptoms judged nine of 11 studies at high or critical risk of bias, reported possible publication bias, and tested massage only combined with other methods.
What are the safety considerations?
Reported harms and gaps in reporting
No source reviewed reports adverse events for Mercier Therapy itself. In the 2023 review of visceral techniques, the included trials reported no adverse effects apart from brief tiredness in one, but that review excluded safety and tolerance studies and covered only 490 people. The authors of the 2004 report called their method noninvasive with few, if any, adverse effects, a statement from an uncontrolled series. Absence of reports does not show that harms did not occur.
Suitability and care boundaries
The sources reviewed do not state which conditions make abdominal and pelvic manual therapy unsuitable, so no contraindications can be listed here. Infertility, endometriosis and pelvic adhesions are medical conditions with defined assessment and treatment options, such as surgery and assisted reproduction, set out with graded recommendations in the ESHRE guideline. Manual therapy should not delay or replace assessment or necessary care, and new or worsening pelvic pain or other symptoms warrant medical review.
Training and regulation
No professional register, curriculum, training standard or code of ethics specific to Mercier Therapy was found in sources that could be opened. The 2013 note describes one practitioner as a licensed massage therapist who is certified under the founder, but the content, length and assessment of that certification were not verified. No statutory regulation specific to the method was found.
