Occasionally, sperm displaying a loop bend in the principal piece with cytoplasmic droplet material trapped in the loop are encountered. The loop begins just past the midpiece, so technically it is not a DMR. Most of the sperm with bent principal pieces are noted in spermiograms where DMRs are present and are believed to have the same origin.
