Effect of alpha-chlorohydrin and vasoligation on epididymal and testicular blood flow in the rat and on sperm parameters. 1978

P D Brown-Woodman, and I G White

Rats were injected subcutaneously with the male antifertility agent, alpha-chlorohydrin (90 mg/kg), and the animals killed 4/24, 2, 5, 10 and 20 days after the injection. Rats in a second series were killed at the same time intervals following bilateral ligation of the vasa efferentia to mimic the effect of the high dose of alpha-chlorohydrin in blocking the initial segment of the epididymis. The epididymides were cut into segments for relative blood flow estimations. There was little change in the pattern of blood flow in the epididymal segments of rats injected with alpha-chlorohydrin, and it appears that interference with the epididymal vasculature is not an important factor in the mode of action of alpha-chlorohydrin. Bilateral ligation of the vasa efferentia produced a marked effect on blood flow through the epididymis. The results suggest that this dose of alpha-chlorohydrin disrupts the motility and morphology of sperm in the epididymis.

D002728	Chlorohydrins	Any of the compounds derived from a group of glycols or polyhydroxy alcohols by chlorine substitution for part of the hydroxyl groups. (McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed)	Chlorhydrins
D004822	Epididymis	The convoluted cordlike structure attached to the posterior of the TESTIS. Epididymis consists of the head (caput), the body (corpus), and the tail (cauda). A network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of SPERMATOZOA.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013081	Sperm Motility	Movement characteristics of SPERMATOZOA in a fresh specimen. It is measured as the percentage of sperms that are moving, and as the percentage of sperms with productive flagellar motion such as rapid, linear, and forward progression.	Motilities, Sperm,Motility, Sperm,Sperm Motilities
D013094	Spermatozoa	Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
