Effect of low doses of alpha chlorohydrin on the enzymes of glycolytic and phosphogluconate pathways in the rat testis and epididymis

A biochemical study has been made of the effects of low doses of alpha chlorohydrin on all the glycolytic enzymes and two key enzymes of phosphogluconate pathway i.e. glucose-6-phosphate dehydrogenase (G-6-PDH) and 6-phosphogluconate dehydrogenase (6-PGDH) of rat testis and epididymis. All the glycolytic enzymes of testis and epididymis are decreased after treatment with alpha chlorohydrin. G-6-PDH and 6-PGDH are decreased only in epididymis and not in the testis. LDH, ADH and glucose-6-phosphatase were also studied histochemically to show that the drug affects the glycolytic enzymes of epididymal cells and various testicular cell types of testis. Possible significance of these results is discussed.

Effect of alpha-chlorohydrin on epididymal sperm and epididymal plasma in swine

Investigation of the contraceptive mechanism of alpha-chlorohydrin was done by analyses of epididymal plasma and certain epididymal sperm characteristics after oral administration of 0, 5, 10 or 30 mg/kg, day of the drug to boars for 15 days. Water resorption in caput epididymidis was slightly decreased in all treatment groups. Sodium, potassium, chloride, glycerylphosphorylcholine levels, and seminal antigens in epididymal plasma were not altered significantly by 10 or 30 mg/kg of the drug. The boars on 5 mg/kg exhibited significantly elevated sodium, potassium, or chloride values in various segments. Motility was significantly lower on corpus and proximal cauda epididymal spermatozoa from alpha-chlorohydrin treated boars. Only boars receiving 30 mg/kg exhibited impaired sperm motility in the distal cauda. The movement of the cytoplasmic droplets to the distal position was retarded in boars on the two highest dose levels. The results suggest that the contraceptive effects of alpha-chlorohydrin in the boar is probably not mediated via an impaired epididymal function.
