Gender-Specific Teleportation

I know that in the Starforce Trilogy, and in Spinrad's "Void Captain's Tale," space travel depends on gender-specific teleportation abilities. Usually female-only.

I wonder what people think of using the idea in stories.

I was planning to use the idea, with modifications, in some space opera stories, because it dodges the physical objections to faster-than-light travel, and it complicates the gender politics of the societies involved. I figure it could involve a drug and/or cybernetic implants that help people do this, but make some people too dysphoric to do this.

I'm not ready to write those stories, so I was wondering about using the same basic idea, in another setting, with people going between parallel universes, and robots, and wish-fulfillment, instead of across interstellar space.

So wha do people think of the idea, and when to use it or not use it.
