Effect of castration, testosterone treatment and hereditary sterility on prostaglandin concentration in the male reproductive system of mice.Prostaglandins. 1975 Feb; 9(2):289-97.P
The concentration of prostaglandins E and F in different parts of the male reproductive system of CD-1 and dwarf mice was measured by radioimmunoassay. In intact CD-1 mice, the vas deferens contained a significantly higher concentration of PGE and PGF than was found in the epididymis and in the seminal vesicles. All tissues studied had more PGE than PGF. Castration resulted in increased PG concentrations in both the epididymis and the seminal vesicles and decreased PG concentrations in the vas deferens. There was also a differential response of PGE and PGF in the epididymis of genetically sterile dwarf mice (dw/dw) were significantly higher than those observed in their normal littermates ((PLUS)). A reversed PGE/PGF ratio was found in the mates. The results indicate that testicular androgens affect the levels of PGE and PGF in the reproductive system of male mice. The physiological role of PGs in male reproductive functions has not been established, but there is a suggestion that PH have a role in controlling the transit of spermatozoa through the epididymis and vas deferens.
