The data that are required are provided by questionnaires.

The other data are provided by saliva measures. This means just simply to spill into a tube. All saliva measurements will be done with a short time period because there are changes during the day.

Spermatograms will be made available with the help of medical doctors and personnel experienced with this tasks.

Pre Analysis Plan

Analyses will be correlational by  using the data gathered from questionnaire (to assess morning types and evening types) on the one side and 

A) testosterone level in saliva

B) Immunocompetence

C) Sperm quality

on the other side. We hope that results can be published even when there is no relationship.
