You can set the itemize item template to use the bibliography item template:
\documentclass{beamer}
\setbeamertemplate{itemize item}{\leavevmode\usebeamertemplate*{bibliography item}}
\begin{document}
\begin{frame}
\begin{itemize}
\item First.
\item Second.
\item Third.
\end{itemize}
\end{frame}
\end{document}
Since the placement of tha backslash is not obvious from the description in the original question, I provide three options using TikZ (the last one suggested by barbara beeton in a comment):
\documentclass{scrartcl}
\usepackage{tikz}
\def\Nmale{%
\tikz{\node[draw,circle,scale=0.5] (a) {};\draw[->] (a.45) -- +(45:4pt);\draw +(a.north west) -- +(a.south east);}}
\def\Nemale{%
\tikz{\node[draw,circle,scale=0.5] (a) {};\draw[->] (a.45) -- +(45:4pt);\draw +([xshift=-1.5pt,yshift=1.5pt]a.north west) -- +([xshift=1.5pt,yshift=-1.5pt]a.south east);}}
\def\Neumale{%
\tikz{\node[draw,circle,scale=0.5] (a) {};\draw[->] (a.45) -- +(45:4pt);\draw +([xshift=-0.5pt,yshift=2.5pt]a.45) -- +([xshift=2.5pt,yshift=-0.5pt]a.45);}}

\Nmale
\Nemale
\Neumale

I am now almost convinced that the backslash should cross only the arrow, so here are some options for male and female:
\documentclass{scrartcl}
\usepackage{tikz}
\def\Neumale{%
\tikz{\node[draw,circle,scale=0.5] (a) {};\draw[->] (a.45) -- +(45:4pt);\draw[very thin] +([xshift=-0.5pt,yshift=2.2pt]a.45) -- +([xshift=2.2pt,yshift=-0.5pt]a.45);}}
\def\Neufemale{%
\tikz{\node[draw,circle,scale=0.5] (a) {};\draw[->] (a.270) -- +(270:4pt);\draw[very thin] +([xshift=-1.9pt,yshift=-1pt]a.270) -- +([xshift=1.9pt,yshift=-1pt]a.270);}}
\begin{document}
\Neumale
\Neufemale
\end{document}

Very simple: you need to use
\in front of the#symbol:
