Observations in this study indicate that androgens regulate
porcine Sertoli cell proliferation. Androgen receptor antagonism
during postnatal Sertoli cell proliferation results in
increased Sertoli cell numbers during treatment. Although we
cannot exclude a role for FSH in the increased Sertoli cell
numbers observed at 6.5 wk of age, the observed increase at 2
wk of age occurs without detectable changes in FSH
concentrations.
