THE EFFECT OF HYPERPYREXIA UPON SPERMATOZOA COUNTS IN MEN

Abstract
The effect of hyperpyrexia on spermatozoa production in normal [male][male] was examined in 6 individuals. The hyperpyrexia was attained by placing the [male][male] in the Burdick diathermy cabinet and elevating the body temp. to approx. 41[degree]C. The elapsed time for this elevation to take place was approx. 32 mins., during which period the environmental temp. was 43[degree]C. Total spermatozoa counts were made on the semen of each individual for some time previous to the fever treatment, and further examinations were made at regular intervals up to 3 mos.'' post-treatment. The total spermatozoa counts remain at normal level for nearly 3 wks. after the heat treatment, after which a steady fall appears, reaching their lowest level at approx. 42 days. Thereafter, the counts show a steady rise and reach a normal level within 25 days.
