One such current conflict between science and religion centers on homosexuality, which science views as just a natural biological phenomena involving a minority of humans.
However, many religions assert that the human-written Word of a (loving?) god is that homosexuality is a disturbed, immoral choice of “normal” humans, despite science's findings of certain genetic and developmental factors (for example, small but non-trivial differences in brain structure, and men with older brothers having an increased chance of being homosexual) that correlate with homosexual humans.
Thus, the possibility of human same-sex procreation is so controversial that it can provide a basis for a variety of new entertainment products, especially movies, television shows and theater productions.
Because of the historic impossibility of creating such
sperm and eggs, and therefore the lack of published science to inspire entertainment creators, it is not surprising that female
sperm (or a male egg) has never been used as a plot element in an entertainment product, especially products having the forms of plot structures disclosed herein.
Not surprisingly in light of the lack of any scientific basis for human female sperm, the article and commentary has not led to any entertainment use of the idea of female sperm, partly because the controversy is little known outside Biblical errancy study circles.
The fourth
paragraph of the article reads: “The creation of ‘male eggs’ and ‘female sperm’, however, faces difficult technical barriers, as embryos require genetic material from both a mother and a father in order to develop normally.”, this
paragraph indirectly referring to problems associated with faulty imprinting.
Not only is there an absence of female sperm as a plot element in the no-limits-to-ideas worlds of science fiction and fantasy, but also there is no published motivation to so use female sperm as a plot element.
And even when a strange new scientific idea is published, it may take many years for someone to invent a use for the scientific idea as a plot element.
But what is generally impossible for humans (but well known for animals, such as snails) is for human hermaphrodites to have both viable sperm and eggs (procreative
hermaphrodite animals typically have ovotestes which produce both sperm and eggs).
It turns out the man started out life as an orphaned woman born with both sex organs and both organs being functional (which is generally impossible for humans).
While the story is a great example of the bizarre entertaining possibilities of time travel, and inspired much time-travel fiction writing (including, possibly, the 1969 science fiction story Slaughterhouse 5 by Kurt Vonnegut), it inspired little to no sexual fiction writing because other than its existence, there is nothing really interesting about having two sets of sexual organs to in theory be able to produce both sperm and eggs.
One explanation for the above-described lack of speculation or fantasy with regards to sperm from women or eggs from men, especially in regards to entertainment, and especially after the few mentions of female sperm around the time of the announcement of the Newcastle research, is due to the problem of the lack of any scientific
biological pathway to actually create sperm from a woman's cells or eggs from a man's cells.
Some scientific possibilities, such as female sperm, are so bizarre that the possibilities need some theoretical basis for non-scientists (such as scriptwriters) to imagine upon to then incorporate such possibilities into known entertainment motifs.
The non-enabling aspects of the Newcastle research and the earlier University of Pennsylvania research include problems due to the
Y chromosome (which females do not possess in their cells, including that region of the
Y chromosome that contributes to sperm production), and imprinting.
Thus given the historic scientific impossibility of creating female sperm from a woman and thus its lack of discussion in scientific literature, and the social taboos involved with some concepts that empower women, to date there have been no entertainment products that make use of creating sperm from a woman's cells.
