Query: General model of sex distribution, mating probability and egg production
  for macroparasites with polygamous mating system   The reproductive habits of helminths are important for the study of the
dynamics of their transmission. For populations of parasites distributed by
Poisson or negative binomial models, these habits have already been studied.
However, there are other statistical models that describe these populations,
such as zero-inflated models, but where reproductive characteristics were not
analyzed. Using an arbitrary model for the parasite population, we model the
distribution of females and males per host, and from these we model the
different reproductive variables such as the mean number of fertile females,
the mean egg production, the mating probability, the mean fertilized egg
production. We show that these variables change due to the effects of a
negative density-dependence fecundity, a characteristic of helminth parasites.
We present the results obtained for some particular models.
