Testes Size as Predictor for Semen Production and Relation to Female Reproductive Traits
Hypor tested testes size and results showed that boars with bigger testes produce semen with a higher concentration of spermatozoa than boars with smaller testes and, therefore producing more doses, although the volume produced is reduced, according to Florence Ytournel, European Geneticist with Hypor. In addition, she found, positive correlation to female reproductive traits, such as total piglets born and percentage of piglets born alive, have been found in boars with larger testes.
