Function

The Cremaster is a component of the thermal regularization for the testicles. If the temperature of the testicles becomes too high, the Musculus relaxes more cremaster, so that the testicles are better cooled further to down-hang and. If the testicles become too cool against it, they are near pulled by the Cremaster more near to the warming body.

Beyond that the Cremaster protects the testicles against injuries. In the case of a provoking of the inside of the thighs the testicles are pulled upward and are such a thing more protected. This procedure calls itself Cremaster reflex, which is a foreign reflex. The responsible persons of segments in back Marks are L1 and L2.

During strong sexual excitation the testicles are pulled likewise very strongly to the body. Thus the length of the seed strand is reduced over up to 50% and so the way of the sperm cellses to the Eizelle is shortened clearly. Thus the probability of a fertilization rises.
