Summary
The disulfide contents of human sperm heads, as measured by reduction to the sulfhydryls and subsequent alkylation with14C-iodoacetamide, increase about 2-fold during the sperm passage from the caput to caudal epididymides. Majority of the increased disulfides reside in the human protamine fractions.
