Effect of Rumex steudelii methanolic root extract on ovarian folliculogenesis and uterine histology in female albino rats
Abstract
Background: A substantial number of the world population especially that of the developing countries rely on herbal products to control their fertility since ancient times. Rumex steudelii Hochst is one of the traditionally used antifertility plants in Ethiopia. Previous studies showed that the methanolic root extract of the plant had reversible antifertility effect in experimental animals. However, no study had hitherto been done on the antifertility activity of the methanolic root extract of Rumex steudelii on the ovary and uterus of female albino rats.
Objective: To investigate the quantitative aspects of follicular development in the ovaries and uterine histology in cyclic female albino rats to get further information on the possible mechanism of antifertility effect of the methanolic extract of R. steudelii.
Methods: The effect of the extract on uterine histology and ovarian follicular growth was determined after oral administration of the methanolic root extract of Rumex steudelii at 2.2, 2.5, 3.0 g/kg/day doses consecutively for 30 days.
Results: The extract significantly decreasing the number of healthy small antral, Graffian follicles and corpora lutea with concomitant significant increase in the number of atretic follicles of the same stage in dose dependent manner. Treatment at 3.0 g/Kg dose level in addition caused a significant decrease in the number of healthy primary, small preantral and large preantral follicles with concomitant significant increase in the number of atretic primary follicles. The ovarian and uterine wet weights are reduced significantly. The extracts also caused a significant decrease in the epithelial cell height, myometrial and stromal thickness in a dose dependent manner.
Conclusion: The study demonstrated that the methanolic extract could cause atrophic changes in the uterus and disruption of ovarian folliculogenesis by inhibiting further development of the recruited ovarian follicles.
Key words: Rumex steudelii, Antifertility, Folliculogenesis, Endometrium, uterus, ovary, ovarian follicles, corpus luteum, Rats.
