ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of cryptotanshinone on androgen synthesis for the prenatally androgenized male rats.</p><p><b>METHODS</b>On days 16-18 of pregnancy, rats were injected s. c. with testosterone propionas continuously for 3 days; male offspring were studied as subject. Serum concentrations of testosterone (T), 17a-hydroxy progesterone (17-OHP), blood glucose, and insulin were measured by radioimmunoassay. Then, the rats were treated with cryptotanshinone by gavage for 14 days, and the levels of serum T, 17-OHP and insulin were detected and the 17a-hydroxylase protein expression in interstitial cell was measured using the method of immunohistochemistry.</p><p><b>RESULTS</b>There was no difference between the male groups who were prenatally androgenized in serum levels of T, but the 17-OHP, fasting insulin levels and homeostatic model assessment for insulin resistance (HOMA-IR) elevated significantly (P < 0.05). Cryptotanshinone could lower the levels of 17-OHP (P < 0.05) but had no effect on 17a-hydroxylase.</p><p><b>CONCLUSION</b>Prenatally androgenized male rats exhibit elevated 17-OHP and diminished insulin sensitivity. Cryptotanshinone could decrease 17-OHP, but has no effect on insulin, indicating it may reduce androgen synthesis.</p>
