Let B_s,t(n)$B_{s,t}(n)$ denote the number of (s,t)$(s,t)$-regular bipartitions. Recently, Dou discovered an infinite family of congruences modulo 11 for B_3,11(n)$B_{3,11}(n)$. She also presented several conjectures on B_s,t(n)$B_{s,t}(n)$. In this paper, utilizing an theta function identity appeared in Berndt's book, we confirm three conjectures on B_3,7(n)$B_{3,7}(n)$ given by Dou. Moreover, we prove several infinite families of congruences modulo 3 and 5 for a721015daeb952ab31e5b25933ee948" title="Click to view the MathML source">B_3,s(n)$B_{3,s}(n)$ and B_5,s(n)$B_{5,s}(n)$. In addition, we prove many infinite families of congruences modulo 7 for B_3,7(n)$B_{3,7}(n)$ by employing an identity of Newman.
