The aim of this paper is the analytical solutions the family of rst-order nonlinear stochastic differential
equations. We dene an integrating factor for the large class of special nonlinear stochastic
dierential equations. With multiply both sides with the integrating factor, we introduce a deterministic
dierential equation. The results showed the accuracy of the present work.
