What do we know about boars

What about courtship. The boars testes secrete large quantities of 16-androstenes, both conjugated and unconjugated. These musk-smelling steroids accumulate in the submandibular salivary glands and serve as pheromones when dispensed with the boar’s saliva during courtship behaviour. At estrus, females recognise these pheromones, resulting in enhanced sexual receptivity.
