Our aim was to explore the effect of telmisartan and/or fish oil on dehydroepiandrosterone (DHEA)-induced PCOS in rats. Sixty female rats were divided into six equal
groups as follows: Control; DHEA-induced PCOS; DHEA + Telmisartan; DHEA + Fish
oil; DHEA + Carboxymethyl cellulose; and DHEA + Telmisartan +Fish oil group.
Plasma sex hormones, anthropometric measurements, and the glycemic indices were
measured. Tissue oxidative stress parameters and the proinflammatory cytokines
were assessed. The ovaries were subjected to histopathological and electron microscopic examination. Telmisartan and/or fish oil induced significant improvement of
insulin resistance with amelioration of oxidative stress and inflammation compared
to PCOS group. Also, telmisartan and/or fish oil restored the hormonal levels and
the anthropometric measurements to the normal values. This was significant with
telmisartan/fish oil combination compared to the use of each of these agents alone.
In conclusion, this combination may represent a promising hope for amelioration of
PCOS.
