The local transfer of @entity251 (T) and immunolocalization of @entity42518 (P450arom) in the spermatic cord vessels of ten male @entity1707 * @entity12526 hybrids were examined in December (short-daylight period) and June (long-daylight period). Total T concentration was determined in the jugular vein (JV) and free T concentration was estimated in the common carotid artery (CA), branches of the testicular artery supplying the testis (TA) and epididymis (EA), as well as in testicular veins draining blood from the testis (TV) and spermatic cord (SV). P450arom was immunolocalized in the arterial and venous vessels of the spermatic cord. The concentrations of total T in the JV and free T in the CA did not differ between the examined periods. However, in December, free T concentrations in the TA and EA were higher (p<0.01-0.001) than in the CA. In June, free T concentration was higher (p<0.01) in EA than in CA and TA. The concentrations of free T in the TV and SV were higher (p<0.001) than in the JV regardless of the period. Also, free T concentration in the SV was higher (p<0.05) in June than in December. P450arom was expressed in all layers of the arterial and venous vessels of the spermatic cord. In June, the intensity of the P450arom staining was higher than in December. The results suggest that the local supply of the male reproductive organs with @entity479 hormones operate in the hybrids of @entity1707 * @entity12526 . This supply includes the local transfer of @entity251 and the P450arom action.
