Epididymal sperm reserve in Buffalo-bulls (Bubalus bubalis).

abstract：:The epididymis responds to adverse conditions of misshapen spermatozoa resulting from pathological changes or toxic insults by secretion of a dense matrix that segregates the latter for complete disintegration and dissolution. The objective of this study was to find the source of this matrix and the role-player of dis...
