Temperature / muscle: Cold makes dartos muscle of scrotal wall, contract. This pushes testes upward. Conversely heat makes dartos muscle relax & testes move down. Different mechanism which pulls testes up is contraction of cremaster muscle. Attatched to internal oblique muscle of lateral abdominal wall. Muscle can be very active in boys from age about 2 years till pre-puberty & responsible for normal retractile testes.
