Convincingly demonstrated by immunocytological methods in females of several mammalian species, relaxin has not yet been localized in the male. Immunocytologically, a related antigen was identified in adult normal boar testes using and anti- [NIH P-relaxin/HSA] antiserum free of anti HSA Abs. A strong reaction was observed in interstitial cells, a weaker but very clear one in Sertoli cells. NIH P-relaxin and HC1-acetone extracts of either corpora lutea from pregnant sows or boar testes inhibited the immunofluorescence of the reactive structures in the boar testes as well as in ovaries of pregnant sows. Ethanol-acetone precipitates from boar rete testis or caudal epididymal fluids inhibited the reaction of interstitial and Sertoli cells, but this inhibition in the sow was limited only to degenerative ovarian structures, probably due to an insufficient level of inhibiting antigen in these two seminal fluids, in contrast with the very high concentration of relaxin in luteal cells of pregnant sows. Specific immunofluorescence was observed neither in ectopic testes of adult monocryptorchid boars (contrary to scrotal testes in these same animals) nor in testes of prepuberal pigs. The specificity and meaning of these results are discussed.
