Abstract

Rotation of living guinea-pig spermatozoa can be effected by drawing the shaft of a long microneedle of diameter 0.5 to 1.0 μ across the tail; the special characteristics of this rotation demonstrated in the tail a polygonal structure and high resistance of the peripheral fibrils to deformation by pressure of the microneedle.
