Abstract

Objectives

In Endometriosis is a gynecological disorder characterized by the growth of endometrial tissue outside the uterine cavity that is associated with chronic pelvic pain and subfertility. The purpose of the study was to investigate the effect of broccoli extract (BE) alone and in combination with soy isoflavones (SI) on endometrial implants in female rat.

Methods

In this study, endometriosis was induced surgically in 40 mature female rats. The rats were divided into 5 groups that were treated by oral gavage for 6 weeks with 0.5 mL of saline 0.9 %/day (control group), BE (3,000 mg/kg/day), SI (50 mg/kg/day), BE/soy isoflavones (BE 3000 mg/kg/day + soy isoflavones 50 mg/kg/day) and diphereline as a standard medication (3 mg/kg) intramuscularly. At the end of treatments, the volume and histopathology of the endometrial implants were compared among the 5 groups. The serum levels of oxidative parameters including superoxide dismutase (SOD), malondialdehyde (MDA) and tumor necrosis factor alpha (TNF-α) were also compared between the groups. The volume of the implants significantly decreased in diphereline group (p=0.002).

Results

The histopathological grade of endometrial implants in BE/SI and diphereline group were significantly decreased compared to the control group (p=0.001). The serum levels of SOD in BE group were enhanced significantly in comparison to the control group (p=0.034).

Conclusions

BE in combination with SI decreased the growth and histopathologic grades of transplanted endometrial implants. These herbal compounds may have the potential therapeutic effect to be used as an alternative medication for the treatment of endometriosis.

Lay summary

Endometriosis happens when tissue similar to the uterus tissue grows outside of the uterus. It can be associated with severe pelvic pain and make several difficulties to get pregnant. Since the use of hormonal drugs is prohibited when planning to get pregnant and due to the common recurrence of lesions after surgery, scientists have been encouraged to study regarding the efficacies of natural products on improvement of endometriosis. In this study, it is represented that the dietary consumption of broccoli extract combined with soy isoflavones may have potential beneficial properties on clinical symptoms of endometriosis.
