  We reexamine a succesful fermion mass Ansatz proposed by Giudice for a wide
range of the ratio $tan\beta =\frac {<\bar h>}{<h>}$ (where ${\bar h},h$ are
the two standard higgs fields), in the context of supersymmetric grand unified
theories. We find that the 7 predictions of the ansatz, $V_{us}, V_{cb},
V_{ub}, m_u, m_d, m_s$ and $m_b$ are in good agreement with the experiment when
either {\it i) } $tan\beta \simeq 1$ or {\it ii)} $tan\beta \geq 30$. A correct
prediction for the bottom mass gives a lower limit on $m_t\geq 125$ for case
{\it (i)}, in agreement with the previous analysis, while in case {\it (ii)}
$m_t\geq 145$.
