The male symbol ♂ is the astrological symbol for Mars
and the female symbol ♀ is the astrological symbol for Venus.
To insert ♂/♀ in Microsoft word (PC version), use the "Insert/Symbol..."
funtion on the menu. A window displays special symbols and characters will open.
Ironically, don't select the font "Symbol". Select a font such as "Times New Roman".
Scroll down one should find the ♂/♀ symbols.
For both Mac and PC, Astrological fonts can be purchased from Fonts.com.
For web publication, the html (unicode) codes for male and female symbols are
♂ (♂) and ♀ (♀).
