Hypothesis to Explain Subfertile Semen

There is general agreement that even small increases in temperature from experimental application of external heat can cause disruption of spermatogenesis and sperm maturation with alteration of semen parameters. It is now apparent that intrinsic elevation of temperature can be identified in the presence of subfertile semen. Such increases in temperature above normal appear small: 0.5 – 1.5°C.
