Abstract
Tartrazine is a yellow colouring agent that is commonly used in foods; however, high dosages of Tartrazine affect fertility and create oxidative stress by generating free radicals. A plant species known as Stevia rebaudiana has natural antioxidants that show promise for protecting testicular tissue. Consequently, this study was intended to examine the ameliorative effect of the aqueous extract of S. rebaudiana (Stevia) on the fertility of male Wistar rats induced by the daily oral intake of Tartrazine. Utilizing gas chromatography-mass spectrometry, phytochemical identification was accomplished for Stevia extract. Study groups were separated into several groups: the first group (the control) got distilled water for up to 56 days; the Stevia group (1000 mg/kg), the Tartrazine group (300 mg/kg) and the Stevia and Tartrazine group (the group was given Tartrazine after 1 h of Stevia extract intake). Also, the oxidative damage in testicular tissues was assessed by measuring the levels of malondialdehyde (MDA) and antioxidants (catalase [CAT], superoxide dismutase [SOD] and glutathione reductase [GSH]). Further, histological alterations were examined. In addition, cyclic AMP-responsive element modulator (Crem) gene expression levels and their relative proteins were measured in the testicular tissues using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assays, respectively. Sperm analysis and testosterone concentration were also performed. SPSS version 25 was used for the analysis of results while (p < .05) was regarded as significant. Compared with the control group, the results demonstrated that Tartrazine caused a significant reduction (p < .05) in the testosterone hormone level (0.70 ± 0.21) and the Crem protein quantity (1.21 ± 0.23) in the treated Tartrazine group. Also, it had a significant decrease (p < .05) in sperm motility, viability, count and antioxidant levels. Moreover, there was a significant increase (p < .05) in sperm abnormalities, MDA level (7.40 ± 1.10), kidney and liver function parameters, and DNA degradation in the treated Tartrazine group compared with the control group. On the contrary, the Stevia extract intake enhanced the testosterone (2.50 ± 0.60), antioxidants and Crem protein levels (2.33 ± 0.10) with an improvement in sperm quality in the Stevia and Tartrazine-treated group compared with the Tartrazine group. Stevia also caused a significant decrease (p < .05) in the MDA level (3.20 ± 0.20), and sperm abnormalities with an enhancement of the liver and kidney function parameters in the Stevia and Tartrazine-treated group compared to the Tartrazine group. Stevia administration has a protective effect on the testicular tissues and sperm quality against toxicity induced by Tartrazine exposure, so it will be a good antioxidant drug to be administered daily before daily administration of Tartrazine.

Abstract
Androgen is a kind of steroid hormone that plays a vital role in reproductive system and homeostasis of the body. Disrupted androgen balance serves as the causal contributor to a series of physiological disorders and even diseases. Flavonoids, as an extremely frequent family of natural polyphenols, exist widely in plants and foods and have received great attention when considering their inevitable consumption and estrogen-like effects. Mounting evidence illustrates that flavonoids have a propensity to interfere with androgen synthesis and metabolism, and also have a designated improvement effect on androgen disorders. Therefore, flavonoids were divided into six subclasses based on the structural feature in this paper, and the literature about their effects on androgens published in the past ten years was summarized. It could be concluded that flavonoids have the potential to regulate androgen levels and biological effects, mainly by interfering with the hypothalamic-pituitary-gonadal axis, androgen synthesis and metabolism, androgen binding with its receptors and membrane receptors, and antioxidant effects. The faced challenges about androgen regulation by flavonoids masterly include target mechanism exploration, individual heterogeneity, food matrixes interaction, and lack of clinical study. This review also provides a scientific basis for nutritional intervention using flavonoids to improve androgen disorder symptoms.
