Fig. 1.

Patterns of urinary androgen excretion across gestation in female white-faced marmosets. Values indicate mean ± s.e.m. Filled circles represent females that were carrying litters that were 50% or more males (n =12); open circles represent females whose litters were less than 50% male fetuses (n = 6). Day 0 reflects mean androgen excretion in nonpregnant females immediately prior to conception. See Table 1 for additional details.
