Japan Endometriosis Association publishes third national study

APRIL 2007

The Japanese Endometriosis Association has announced preliminary results from their National Endometriosis Survey showing adverse emotional effects of GnRH-analogues when used in endometriosis

Logo from JEMAThe Japan Endometriosis Association (JEMA), founded in 1994, conducts a national endometriosis survey every five years.

Their 2006 data (n=668) shows that 28% of respondents suffer depression whilst using GnRH-a, with 16% having suicidal thoughts, and 2% actually attempting suicide.

JEMA has often had meetings with and made petitions to the Ministry of Health, Labour and Welfare (MHLW) in recent years, and has strengthened its political ties. It has repeatedly called for the increased use of standard global medical treatment in Japan, including the low-dose contraceptive pill, promotion of laparoscopic surgery for diagnosis, and a reduction in the empirical use of GnRH-a due to the side-effects reported above.

The low-dose contraceptive pill was not approved until September 1999 in Japan. However, its use has not spread because MDs hesitate to prescribe pills without insurance coverage, and with a lack of knowledge and experiences they do not recommend this to patients. And so, since the autumn of 2002, JEMA has been involved in the project for applying for health insurance coverage for endometriosis.

More recently JEMA has translated the ESHRE Guideline for the Diagnosis and Treatment of Endometriosis into Japanese. The guideline is reviewed annually, by an international panel of experts, according to evidence-based principles.

JEMA has been educating women with endometriosis and working with health care professionals in Japan for the past 13 years. It publishes a semi-annual newsletter and semi-monthly mail magazine.

Masumi INUI , Executive Representative of JEMA, is an author of books on endometriosis and writer/editor of JEMA publications, and she is an occasional guest speaker of medical meetings or TV programs as a recognised endometriosis specialist.
