For my thesis I need a symbol for neutered male (veterinary medicine) which is a mars symbol with a backslash superimposed. With the descriptions I found, it didn't work for my document. I'm using scrartcl as documentclass which I can't change because of my reference style.

could you show an example of how it looks like? –  pythonista Sep 27 '12 at 13:47
    
Isn't it simply \not\Male ? –  tohecz Sep 27 '12 at 16:06

@tohecz: Do you mean \usepackage{wasysym} together $\not\male$? In that case, it doesn't work very well because \not produces a forward slash, and the slash doesn't go through the symbol properly. –  Jake Sep 27 '12 at 16:09

@pikatma -- is this a commonly used symbol (in veterinary medicine, it seems quite reasonable)? if so, can you cite a published example of its use? i don't believe it's in unicode yet, but with a good citation, i can arrange to have it considered. –  barbara beeton Sep 27 '12 at 17:39

As you didn't state clearly how your symbol should look like, here are some examples (with and without TikZ). For the \Neumale symbol exists a Unicode character: U+26A6

Code

\documentclass{scrartcl}
\usepackage[nointegrals]{wasysym}
\usepackage{graphicx}
\usepackage{tikz}\usetikzlibrary{calc}
\def\notmaleanymore{\leavevmode\kern.07em\raise.1ex\hbox{\scalebox{.7}{\bfseries\textbackslash}}\kern-.47em\male}
\def\neumale{\tikz{\node[inner sep=0pt] (male) {\male};\draw ($(male.south west)!.65!(male.center)$) +(135:.19em) -- + (-45:.2em);}}
\def\Neumale{\tikz{\node[inner sep=0pt] (male) {\male};\draw ($(male.south west)!1.20!(male.center)$) +(135:.15em) -- + (-45:.15em);}}
\def\neufemale{\tikz[baseline=-0.4ex]{\node[inner sep=0pt] (female) {\female};\draw (female.center)++(-.01em,.17em) +(135:.19em) -- + (-45:.2em);}}
\usepackage{fontspec} % needs XeLaTeX
\begin{document}
\noindent \male \notmaleanymore \neumale \Neumale \female \neufemale\\
\fontspec{LinLibertine_R.otf} % needs XeLaTeX
\char"2642                    % needs XeLaTeX
\char"2640                    % needs XeLaTeX
\char"26A6                    % needs XeLaTeX
\end{document}

Output

some gender symbols

the definition needs at least \leavevmode at the beginning to avoid an error if it happens to be used in vertical mode. –  barbara beeton Sep 27 '12 at 17:37
    
@barbarabeeton Thanks. I've updated my answer. –  Qrrbrbirlbel Sep 27 '12 at 18:02

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);}}

\begin{document}

\Nmale

\Nemale

\Neumale

\end{document}

enter image description here

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}

thinking some more about this, it seems possible that the meaning of the symbol might be even more obvious if the slash crossed just the arrow. but someone in the field would be able to comment with more authority. –  barbara beeton Sep 27 '12 at 18:05
    
@barbarabeeton your option makes sense; I've added it to my answer. –  Gonzalo Medina Sep 27 '12 at 18:18
    
tiny niggle: length of slash looks good, but the visual effect is that it's closer to the arrowhead than to the circle. (without claiming to be an expert) i think it would look clearer with the slash just a bit closer to the circle, maybe by the thickness of the slash. –  barbara beeton Sep 27 '12 at 18:30
    
@barbarabeeton yes, you're right; I've incorporated your suggestion to my updated answer (the slash is thinner and closer to the circle); I also added a female version. Thank you. –  Gonzalo Medina Sep 27 '12 at 18:54
    
For the latter variant there is a unicode character: U+26A6 "male with stroke sign (= transgendered sexuality)". –  Heiko Oberdiek Sep 27 '12 at 19:11
