    OBJECTIVE: The aim of this overview was to evaluate the effectiveness of phytoestrogens on vaginal health and dyspareunia in peri- and post-menopausal women.

    MATERIAL AND METHODS: Three databases including MEDLINE, Scopus and the Cochrane Central Register of Controlled Trials were from inception to August 2017.

    RESULT: Two systematic reviews and 11 RCTs were included in the overview. According to the findings, isoflavones increased the maturation value and attenuated the vaginal atrophy in the post-menopausal women. Topical isoflavones had beneficial effects on the vaginal atrophy. Similar efficacy was found in Pueraria mirifica and conjugated estrogen cream on dryness ( p = 0.277), soreness ( p = 0.124) and irritation ( p = 0.469), as well as discharge ( p = 0.225) and dyspareunia ( p = 0.089). However, the conjugated estrogen cream was more effective compared to Pueraria mirifica ( p > 0.005) regarding maturation index improvement. Comparison of fennel 5% vaginal cream and placebo gel showed significant difference in superficial cells ( p

    OBJECTIVES: Genistein is known to influence reproductive system development through its binding affinity for estrogen receptors. The present study aimed to further explore the effect of Genistein on the development of the reproductive system of experimental rats.

    METHODS: Eighteen post-weaning female Sprague Dawley rats were divided into the following groups: (i) a control group that received vehicle (distilled water and Tween 80); (ii) a group treated with 10 mg/kg body weight (BW) of Genistein (Gen 10); and (iii) a group treated with a higher dose of Genistein (Gen 100). The rats were treated daily for three weeks from postnatal day 22 (P22) to P42. After the animals were sacrificed, blood samples were collected, and the uteri and ovaries were harvested and subjected to light microscopy and immunohistochemical study.

    RESULTS: A reduction of the mean weekly BW gain and organ weights (uteri and ovaries) were observed in the Gen 10 group compared to the control group; these findings were reversed in the Gen 100 group. Follicle stimulating hormone and estrogen levels were increased in the Gen 10 group and reduced in the Gen 100 group. Luteinizing hormone was reduced in both groups of Genistein-treated animals, and there was a significant difference between the Gen 10 and control groups (p<0.05). These findings were consistent with increased atretic follicular count, a decreased number of corpus luteum and down-regulation of estrogen receptors-a in the uterine tissues of the Genistein-treated animals compared to the control animals.

    CONCLUSION: Post-weaning exposure to Genistein could affect the development of the reproductive system of ovarian-intact experimental rats because of its action on the hypothalamic-pituitary-gonadal axis by regulating hormones and estrogen receptors.

    Postmenopausal estrogen deficiency often causes bone density loss and osteoporosis. This study evaluated the effects of an oral administration of oil palm leaf extract (OPL) on bone calcium content and structure, bone density, ash weights, and serum total alkaline phosphatase (T-ALP) of estrogen-deficient ovariectomized (OVX) rats.
