In most cultures, astrology is perceived to be a male dominant field, then we're discussing North American culture, you tend to have more women present in practice of astrology. The planets of Mercury and Uranus rule astrology and are of both genders (male and female), along with Mercurial signs Gemini ("male") which are twins and Virgo ("female") is of mother and child (I suppose Jesus before his birth from the Virgin Mary), and feminine Capricorn (more ruled by Saturn) and masculine Aquarius (traditionally under Saturn) with its air sign nature like Libra to have double wavelengths (like a person has two genders). In the middle of the astrological year, Virgo cusp Libra = a combination of the positive (male) and negative (female), the opposite of Int'l Astrology day on March 20th when it is Pisces cusp Aries (the alpha-male and beta-female).
