The purpose of this study was to determine the relative concentrations of inhibin A and B in peripheral serum of the adult male rhesus monkey and to examine the testicular contribution to these circulating forms of inhibin. In addition, inhibin B concentrations were also determined in peripheral sera of neonatal and juvenile males and in spermatic vein blood of adults. Immunoradiometric assays specific for the measurement of inhibin A and B were used. These assays also provided an opportunity to reexamine the physiological significance of a replacement infusion of recombinant human (rh)-inhibin A previously employed to study the role of this hormone in regulating FSH secretion in the monkey. In intact adults, the mean (± se) serum concentration of inhibin B was 1008 ± 184 pg/mL. In contrast, circulating inhibin A concentrations were very low (<46 pg/mL). Inhibin B was consistently detected in neonatal monkey serum (275 ± 57 pg/mL), and concentrations of this inhibin dimer increased throughout postnatal development, reaching maximum values in adulthood. Circulating inhibin A concentrations in neonatal and juvenile monkeys were undetectable (<7 pg/mL). Both forms of inhibin were generally undetectable in castrate sera. The ratio of inhibin B concentrations in testicular venous blood to those in the peripheral circulation was 1.4:1. These findings indicate that, in the male monkey, inhibin B is the principal form of circulating dimeric inhibin, and that this hormone is derived exclusively from the testis. The elevated levels of circulating inhibin B in the juvenile male monkey suggest that, during this phase of development, testicular inhibin B secretion is relatively gonadotropin independent. Additionally, we found that the concentration of circulating inhibin A in castrate animals that had earlier received an iv infusion of rh-inhibin A (832 ng/h/kg BW) was 9881 ± 2135 pg/mL, indicating that this mode of inhibin replacement may not have been entirely physiological.
