The current work has shown [present perfect: present reproducible work] that the motility of
spermatozoa is [simple present: conclusion from present reproducible results] temperature-sensitive under
the conditions employed. This accords with the tenet that scrotal temperature influences [simple present:
accepted knowledge] the functional responses of spermatozoa. The effect of temperature regulation on
volume regulation by spermatozoa will be examined [simple future: what will be done] next.
