Why Are There So Few Female Sith?

Question

I've found very few references to female Sith. I know there were some powerful female Sith, but there aren't many of them.

Is there a reason there are so few female Sith?

I looked through the Wookiepedia, including the main article on Sith, and there was one female Sith from the time of The Brotherhood of Sith and two (or three) other than that, and that was it. While there aren't many female Jedi, there seem to be fewer female Sith.

This is a case where I'd accept an answer like @Sydenam's or @Aye's comments, as opposed to a purely in-universe answer. Or maybe it's that there are fewer female Force-sensitives than male ones. But whether it's due to sexism, or that male authors write better male characters, or that there's something in-universe that causes it, there's still very few female Sith, so it'd be interesting to know if there's a reason for that.

Answer 1

Since I'm very familiar with Strugatsky brothers, I'll expand on Aye's comment with some details, though if Aye comes back later and feels like she'd like to make into his/her own asnwer I'll gladly delete mine

As was noted, in many cases the Sci Fi writers (who are mostly male) sometimes simply can't write a good female lead character. And some are good enohgh at their art/craft that they don't want to do second-rate work just for the sake of having a female heroine.

A good example of this, as Aye noted, were Strugatsky brothers (the most notable Soviet SciFi writers), who generally wrote very good chracterizations and were always stressing the fact that for them, science fiction writing was writing about human nature and human behavior, with SciFi scenery to assist in that goal. However, their heroes were overwhelmingly male, and they addressed the topic with the fans:

• Arkady Strugatsky stated said the following in an interview to "Knowledge is Power" magazine on 3/17/1982 (English translation mine, Russian source http://www.rusf.ru/abs/int/ans-kafe.htm ):

  ВОПРОС: Почему в ваших произведениях, как правило, женщины в главных ролях не выступают?

  QUESTION: Why are there usually no female main heroes in your works?

  А.Н.СТРУГАЦКИЙ: Женщины для меня как были, так и остаются самыми таинственными существами в мире. Они знают что-то, чего не знаем мы. Лев Николаевич Толстой сказал: все можно выдумать, кроме психологии. А психологию женщины мы можем только выдумывать, потому что мы её не знаем.

  A. N. Strugatsky: Women, for me, were always and still remain the most mysterious creatures in the world. They know something we men don't know. Leo Tolstoy said: "you can imagine anything you want except for psychology". And we can only imagine the psychology of a woman since we don't know it.

• In an ongoing offline Internet interview, Boris Strugatsky has stated the same several times.

Answer 2

Love is forbidden to Jedi. While it is not an emotion forbidden to Sith, by any stretch, taking on lovers seemed to be looked upon as abnormal- as it was dangerous and could lead to weakness by being ruled by one's emotinos, instead of ruling them.

I would imagine this has something to do with being more one sex than the other.
