Females don't produce pollen in the sense of plant reproduction. Only males do. The 'pollen' people refer to when talking about females are the trichome heads that fall off during processing and handling. That 'pollen' isn't actually pollen at all, but it
will get you stoned. I have never heard of using pollen or trichome heads to influence the sex of a seedling, and I doubt it would have any effect.
