Reproduction

Unsurprisingly, the Zil are much like humans when it comes to breeding. A male will insert his penis into the female, ejaculate his seed, and fertilize eggs in her uterus. Gestation takes between six and seven months, with the resulting progeny born as fraternal twins or triplets. When a Zil takes an interest in another, he will force himself into close proximity with the other and activate his pheromone glands. Both sexes have such glands all over their bodies, though the highest concentrations are centered on their genitals. It is reported that, with males, the densest and most effective scent is released from their foreskin. For females, both the breasts and the labia have incapacitating levels of this chemical reactant. Breeding with humans is possible and has happened. The resulting children are chimeral in appearance rather than the hybrids that were expected. More data is required.
