Is the chronic use of Ferula harmonis to enhance mice erectile function effective and safe? A histopathological study

Abstract

Many studies are aimed towards a solution for erectile dysfunction which is a worldwide health problem. Medicinal and natural herbal medications have been prescribed but their long-term effects are not well known. This study aimed to investigate the impact of the chronic administration of F. hermonis root extract on the structure of the male mice reproductive organs and their fertility and to study the possible protective role of vitamin C. Sixty male albino mice were divided into 3 groups: the control, the experimental group that received F. hermonis root extract orally (6 mg/kg) for six weeks, and the treated group that received F. hermonis plus vitamin C for six weeks. Serum testosterone level and mice fertility were assessed. At the end of the experiment mice were sacrificed; testis, epididymis, and seminal vesicle were dissected and processed for routine histopathological and immunohistochemical examination. The chronic administration of F. hermonis extract significantly decreased the level of testosterone and partially impaired fertility. Histopathological degenerative changes and a significant reduction in estrogen receptor (ER)β expression were observed in testes, epididymis, and seminal vesicle. Vitamin C administration did not completely protect the testis from these harmful effects. Although F. hermonis roots are recommended to improve erectile and fertility problems, it should be used for short periods and with extreme caution. Further clinical studies to assess safety and efficacy are needed.
