These methods are designed to use cross-sectional, egocentrically sampled sexual network data to estimate a model for network dynamics, and then use this model to generate dynamic stochastic complete network simulations.
In this sample, sexual abuse perpetrated by parents/adult caregivers began particularly early.
Upon returning from the ocean to their natal streams to spawn, all migrants were sampled at sexual maturity.
Resident trout from the Sashin Creek, Alaska population also were sampled at sexual maturity (tested for the expression of gametes).

Techniques applied for studying male reproductive physiology in these species are often invasive and stressful (i.e. repeated blood sampling for sexual steroids analysis).
Only a more exhaustive sampling of sexual populations could, perhaps, indicate which scenario is more likely.
In this method, called egocentric sampling of sexual partnerships, subjects describe the features of the partnership (start and end dates) and attributes of the partners, as well as epidemiologically relevant behaviors like frequency of sex acts and condom use (Morris 2004).
