In March 2001, Commat organised a consultation at the Royal College of Obstetricians and Gynaecologists in London which brought together 27 heads of university departments of obstetrics and gynaecology, experts in sexual and reproductive health, specialists in family planning and preventive health care, key nongovernmental organisations and specialists in areas such as gender, HIV/AIDS and adolescent health from Commonwealth countries, including Kenya, Uganda, Nigeria, Ghana, Tanzania, India, Singapore, UK and Canada, and also from the USA.
Three approaches were identified at the Commat consultation for the introduction of sexual and reproductive health into the basic curriculum.
The Commat consultation thought that the integrated approach may be more effective in the long term as it represents the most in-depth introduction of ICPD concepts.
