Abstract EN
Estrogen (E) and testosterone (T) are important in the sexually dimorphic pattern of blood pressure (BP) development.
The goal was to examine the effects of endogenous E and exogenous T in the development of hypertension in female spontaneously hypertensive rats (SHR) on a high sodium diet.
Female SHR (N=27, 5-week) were divided into four groups: (1) control (n=8), (2) ovariectomized (OVX, n=26), (3) testosterone implants with intact ovaries (T, n=6), and (4) ovariectomized + testosterone implants (OVX+T, n=7).
T was given immediately after OVX and replaced every two weeks and they were fed a 3% NaCl diet.
BP was measured weekly and plasma norepinephrine (NE) analyzed by HPLC.
OVX+T females exhibited the greatest elevation in BP (190 ± 4.0 mmHg) compared to controls at 15 weeks of age (140 ± 3.4 mmHg, P<.001) and a pattern of hypertension development similar to that of male SHR.
Females with T treatment showed evidence of glomerulosclerosis.
In conclusion, T accelerated the development of hypertension similar to the BP pattern observed in males; the presence of ovaries attenuated the T induced increase in BP; T increased renal sodium reabsorption, and T increased glomerulosclerosis.
