Isoliquiritigenin ameliorates paroxetine-induced sexual dysfunction in male albino mice.

Paroxetine (PRX), a widely prescribed antidepressant, often leads to sexual dysfunction. The available management options such as sildenafil (SDF), are associated with side effects. The present study investigates the fertility-boosting properties of isoliquiritigenin (ISL) on PRX-induced sexual dysfunction in male mice. We allocated fertile mice into six different groups (n = 5): group I- DMSO; group II- PRX; group III- co-administered PRX and SDF; group IV- ISL alone; group V- co-administered PRX and ISL (low dose); and, group VI- co-administered PRX and ISL (high dose). 14 days post treatment, animals were sacrificed, and the weights of the testis and epididymis were evaluated. Furthermore, sperm parameters, testicular and epididymal antioxidant levels, serum testosterone and nitric oxide (NO) levels, histoarchitecture of testis and epididymis, and markers of cellular toxicity were assessed. Results revealed that the PRX administration reduced organ weights, sperm count, intact acrosome, catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), serum testosterone, and NO levels, and increased sperm abnormalities and MDA levels (a biomarker for lipid peroxidation). Additionally, we observed damage in the testis and epididymis. The toxicity biomarker study revealed a higher concentration of SGOT, SGPT, and ALP enzymes in the PRX-treated group. However, the co-administration of PRX with ISL ameliorated the adverse effect of PRX on the parameters mentioned above. The PRX+ISL (high) results were almost at par with the PRX+SDF group. The group that received ISL alone showed overall improvements. In conclusion, our comprehensive panel of tests indicates that ISL could be helpful in managing sexual dysfunction.

Effect of Environmental Stressors, Xenobiotics, and Oxidative Stress on Male Reproductive and Sexual Health.

This article examines the environmental factor-induced oxidative stress (OS) and their effects on male reproductive and sexual health. There are several factors that induce OS, i.e. radition, metal contamination, xenobiotic compounds, and cigarette smoke and lead to cause toxicity in the cells through metabolic or bioenergetic processes. These environmental factors may produce free radicals and enhance the reactive oxygen species (ROS). Free radicals are molecules that include oxygen and disbalance the amount of electrons that can create major chemical chains in the body and cause oxidation. Oxidative damage to cells may impair male fertility and lead to abnormal embryonic development. Moreover, it does not only cause a vast number of health issues such as ageing, cancer, atherosclerosis, insulin resistance, diabetes mellitus, cardiovascular diseases, ischemia-reperfusion injury, and neurodegenerative disorders but also decreases the motility of spermatozoa while increasing sperm DNA damage, impairing sperm mitochondrial membrane lipids and protein kinases. This chapter mainly focuses on the environmental stressors with further discussion on the mechanisms causing congenital impairments due to poor sexual health and transmitting altered signal transduction pathways in male gonadal tissues.

Polycystic Ovary Syndrome: An Updated Overview Foregrounding Impacts of Ethnicities and Geographic Variations.

Polycystic ovary syndrome (PCOS) is one of the most common heterogeneous conditions of the endocrine reproductive system in women of childbearing age. Hyperandrogenism and oligomenorrhea are the two core characteristics of PCOS, a complicated and multifaceted illness. The condition is also linked to several major side effects, which include type 2 diabetes, early atherosclerosis, infertility, and endometrial cancer. There are few facts and statistics available on PCOS prevalence internationally due to the significant degree of geographic and ethnic variance and inconsistency caused by different diagnosis standards. Limited (n = 179) explorations have been made in the context of the prevalence of this complicated illness so far, and out of these, only 55 studies have discussed its association with race and/or ethnicity. However, those studies remain restricted due to the small sample size, biased selection, and the lack of comparative studies. Variations in PCOS prevalence frequency also arise due to different diagnostic criteria, as well as racial and ethnic differences, associated lifestyle factors, and subsequent illnesses that affect the accuracy of the diagnosis. The main objective behind this systematic review is to provide comprehensive epidemiological data on PCOS that is organized geographically. This evidence-based study also provides an overview of the clinical management of PCOS to instigate further research on this complex endocrinological condition and the subsequent development of preventive treatment strategies.

Clinical Potential of Himalayan Herb Bergenia ligulata: An Evidence-Based Study.

Herbal products have been used in traditional systems of medicine and by ethnic healers for ages to treat various diseases. Currently, it is estimated that about 80% of people worldwide use herbal traditional medicines against various ailments, partly due to easy accessibility and low cost, and the lower side effects they pose. Bergenia ligulata, a herb ranging from the Himalayas to the foothills, including the north-eastern states of India, has traditionally been used as a remedy against various diseases, most prominently kidney stones.

Effects of butylparaben exposure on thyroid peroxidase (TPO) and type 1 iodothyronine deiodinase (D1) in female Wistar rats.

Endocrine disrupting chemicals (EDCs) have been considered as one of the major contributors of growing burden of thyroid disorders across the globe, and most of these chemicals have the potential to disrupt thyroid hormones (THs) synthesis and other regulatory pathways of thyroid gland function. Butylparaben (BP), an established xenobiotic used as synthetic preservative, has not been thoroughly evaluated for its molecular mechanism of thyroid disrupting potential. We investigated the effects of BP on activity and gene expression of thyroid peroxidase (TPO) and type 1 iodothyronine deiodinase (D1) in female Wistar rats following subcutaneous exposure to BP at doses of 1, 5 and 10 mg/kg BW/day (expressed as BP1, BP5 and BP10 respectively) for 7 and 21 days. The results showed that BP1 and BP5 significantly increased serum T3/T4 ratio and TSH level, while BP10 reduced the level of T4 significantly without any apparent consequences on TSH and T3 levels. TPO activity in thyroid was significantly increased (p < 0.05) at BP1 and BP5, but BP10 treatment showed no effect like 17ß-estradiol (E2). After 7 days of exposure, BP reduced D1 activity in kidney in a dose-dependent manner, while decrease in D1 activity was significant only after dosing with BP1 for 21 days (p < 0.05). Moreover, 7 and 21 days of BP exposure caused significant fold increase of Tpo mRNA levels in thyroid. In kidney, BP down-regulated the Dio1 gene (encodes D1) expression after 7 days, but significant fold increase was observed following 21 days of treatment. In conclusion, the present study revealed that BP exposure altered the transcriptional expression and activity of TPO and D1, where TSH reinforced possible association with TPO activity.

Using Qualitative Methods to Explore Farrier-Related Barriers to Successful Farriery Interventions for Equine Welfare in India.

Farriery is a critical component of healthcare services for working equids. However, in India, an informal workforce, lack of structured training facilities and non-implementation of farriery regulations pose challenges for quality farriery. Brooke India, an equine welfare organisation, has undertaken many initiatives aiming to improve farriery services, including technical training and engagement with equid-owning communities. However, this has met with varying success. The study aimed to identify factors that prevent farriers providing quality farriery services. Focus-group discussions were conducted with farriers from two districts of Uttar Pradesh with varying programme outcomes. Within each area, farriers were grouped according to previous level of engagement with Brooke programmes. Demand for services, farrier status, the external environment and technical training and knowledge were identified as key elements that affected farriery work. These factors were very context specific: in areas where brick kilns provided the majority of customers, recent closures had resulted in an increase in those farriers' feeling of insecurity. A systems approach to improving farriery services, taking these factors into account, is advised. Mentoring-based capacity building, which is closely aligned to farrier needs and expectations, is expected to have positive results in terms of technical skill and farrier engagement.
