Abstract
Summary
Serum FSH was measured by radioimmunoassay in developing normal and androgenized male and female rats. Immature, 30-day-old, as well as mature, 60-day-old males had higher concentrations of this gonadotropin than females. Serum FSH declined in androgenized females (50 μg of testosterone propionate, fifth day of age) between days 20 and 30. The level remained low at 60 days but was at about the level of normal females at 1 year. The results support the conclusion that androgenization in the female does not produce the male pattern of high serum FSH.
