This paper presents the findings of the sociocultural research survey of JOICFP concerning the issue of male involvement in reproductive health (RH) and its incorporation into programs and activities. The survey was conducted from May 1998 to September 1999 in four countries; namely, Bangladesh, Laos, Nepal, and the Philippines. It aims to provide information and assist program design in a more substantive way than quantitative research. Semistructured group interviews were performed with men in five age groups: adolescent males, 10-12 years and 16-18 years old, and adult males, 20-30 years old (never married), 20-34 years old (married), and 35-49 years old (married). Findings revealed that all age groups in four countries view that men are superior physically and psychologically to women. All the age groups had various general health and RH concerns. They were aware of sexually transmitted diseases (STDs) and HIV/AIDS, but many had little or imprecise ideas as to the causes. There was a tendency to ignore minor illnesses and avoid visiting a clinic or hospital among the adult males. STDs were especially regarded as shameful and RH services were perceived to target women and children. Moreover, married men were found to have less knowledge of women's RH matters compared with adolescents. Each country had specific recommendations, and some of the common ones were the need for information, education, and communication strategies to focus on raising awareness on RH and gender related issues.
