Prostitution is a hatred profession in Bangladesh. In fact people feel embarrassed to utter this word. The dead body of a prostitute is not allowed to be buried or cremated by the mainstream people. The prostitutes lead a risky and vulnerable life because their human rights are frequently violated here. Some sociological theories like deviant behavior approach, differential association theory, feminist approach, and economic theories have been found relevant to explain prostitution through this study. The data have been collected by conducting semi-structured interview, case study and observation. In fact, various psycho-social, economic and other factors i.e. the pull and push factors act in a cyclical way to keep prostitution alive here. The study has also explored some socio-demographic, psychological and economic aspects like education, age, marriage and divorce, income, health and treatment, HIV/AIDS, drug addiction, frustration, anxiety, thinking, experience of physical and sexual oppression/torture, exploitation, rehabilitation, and the daily life style of the prostitutes etc. for explaining the situation of female prostitutes living and working in Sylhet City of Bangladesh.
