In Saudi Arabia, it is widely believed that women with reproductive problems can use the extract of the sage plant as a tea drink. This study was conducted to investigate the effects of this herb on the fertility of female rats and embryo implantation. Forty-eight Wistar virgin female rats were divided into four groups at random, with 12 rats in each group. The control group received distilled water orally. The three treatment groups received different concentrations of sage extract: 15, 60, or 100 mg/kg for 14 days before mating, then mated with a male and sacrificed on the 7th day of gestation, the uterine horns removed, and photographed. The total body weight of mothers, weight of uteri and ovaries and number of fetuses were determined. Ovarian and uteri tissues were cut into 5 μ sections and stained with hematoxylin and eosin. Serum FSH, LH were determined by the ELISA method. The present study showed that low dose of sage (15 mg/kg) have no effects on serum concentration levels of FSH and LH hormones, also has no effect on the number of growing follicles. The present study showed a significant differences (P≤0.05) in body weight, ovary and uterus weight in the groups treated with high doses of Salvia officinalis as compared to control group. Also a significant differences (P≤0.05) found in FSH, LH hormones. Histological study showed overall histomorphological structural configurations including growing and matured graafian follicular countable changes, besides a number of corpora lutea and regressed follicles in the treated groups with high doses of Salvia officinalis as compared to control group. The researchers concluded that the extract of the sage plant with high doses can stimulate the growth graafian follicles and improve fertility in female rats.
