Benzodiazepines related sexual dysfunctions: A critical review on pharmacology and mechanism of action / Disfunciones sexuales relacionadas con las benzodiazepinas: una revisión crítica sobre farmacología y mecanismo de acción

INTRODUCTION: Normal sexual functioning of both men and women, being a very complex process, is affected by numerous issues besides aging. Many factors affect the sexual function and lifestyle of the young population. In this article, we tried to review the literature to update the knowledge on benzodiazepine-related (BZD) sexual dysfunction (SD) and involved mechanisms of actions based on animal and human studies. METHODS: Different standard websites such as PubMed were used to review the literature and keywords including benzodiazepines, sexual dysfunction, gammaaminobutyric acid A (GABAA) receptor and erectile dysfunction were used. RESULTS: SD is one of the most common disorders in males and females which has recently been demonstrated to be associated with psychotropic medications such as antihypertensive agents, tranquilizers, antihistamines, appetite suppressants, antidepressants and anxiolytics. BZDs are among the most common psychotropic agents worldwide. SD including decreased libido, erectile dysfunction (ED) and other undesired sexual urges were observed in the patients receiving BZDs. DISCUSSION: The mechanisms of action of BZDs to induce SD mainly relate to enhanced GABAA receptor function which reduces penile erection

INTRODUCCIÓN: El funcionamiento sexual normal de los varones y las mujeres, al ser un proceso muy complejo, se ve afectado por numerosos problemas, además del envejecimiento. Muchos factores afectan a la función sexual y al estilo de vida de la población joven. En este artículo intentamos revisar la literatura para actualizar el conocimiento sobre las disfunciones sexuales (SD, por sus siglas en inglés) relacionadas con benzodiacepinas (BZD) y los mecanismos de acción involucrados en estudios con animales y humanos. MÉTODOS: Se utilizaron diferentes sitios web estándar, como PubMed, para revisar la literatura y las palabras clave que incluyen BZD, disfunciones sexuales, ácido gamma-aminobutírico A y disfunción eréctil. RESULTADOS: Las SD son uno de los trastornos más comunes en los varones y las mujeres, ya que recientemente se ha demostrado que están asociados a medicamentos psicotrópicos como agentes antihipertensivos, tranquilizantes, antihistamínicos, supresores del apetito, antidepresivos y ansiolíticos. Las BZD son uno de los agentes psicotrópicos más comunes en todo el mundo. Las SD que incluían disminución de la libido, la disfunción eréctil (DE) y otros impulsos sexuales no deseados, se observaron en los pacientes que recibieron BZD. DISCUSIÓN: Los mecanismos de acción de las BZD para inducir SD se relacionan principalmente con la función mejorada del receptor de ácido gamma-aminobutírico A (GABAA) que reduce la erección del pene

Co-administration of Aluminum Sulfate and Propolis Regulates Matrix Metalloproteinases-2/9 Expression and Improves the Uterine Leiomyoma in Adult Rat Model.

The aim of this study was to evaluate the effects of aluminum sulfate (alum) with propolis (PR) on uterine leiomyoma (UL) in rat model. One hundred and four female Wistar rats (180-200 g) were allocated into two main groups of control (Co, n = 8) and experiment (UL model [estradiol benzoate 200 µg/kg/IM twice/week/8 weeks] with/without treatment) defined in 13 subgroups with/without treatment with coil oil (UL + COi), PR (100 or 200 mg/kg) as UL + PR100 or 200, alum (35, 75 or 150 mg/Kg) as UL + AL 35, 75, or 150, and PR (100 mg/kg or 200) with alum (35, 75, or 150 mg/Kg) as UL + PR100 or 200 + AL35, 75, or 150. Subgroups received doses of therapeutics for 14 days (IP). In the end, rats were sacrificed, and the uteri were isolated for molecular and histopathological investigations. The myometrium thickness, collagen contents, and gene expression of MMP-2 and 9 increased significantly in experimental groups with/without treatment (P Ë‚ 0.05). PR administration (100 and 200 mg/kg) alone or with alum (35 and 75 mg/kg) significantly decreased myometrium collagen contents and the gene expression and protein concentration of MMP-2 and 9 compared with UL and UL + Coi subgroups (P Ë‚ 0.05). Alum (75 mg/kg) with PR (200 mg/kg) could improve UL features and reduce MMP-2 and 9 gene expression.

Dietary supplements in the management of varicocele-induced infertility: A review of potential mechanisms.

Varicocele is a main cause of lower production of spermatozoon and infertility with multiple pathophysiological mechanisms. In the past decades, the use of dietary supplements has significantly increased due to both the modern lifestyle and the food shortages of the industrialised countries. The purpose of this review paper is to collect scientific evidences from basic and clinical studies which support the use of dietary supplements to define the clinical framework for patients with varicocele. In the present review, we used keywords such as dietary supplements, varicocele, male infertility, oxidative stress, DNA fragmentation, sperm parameters to find the proper articles. The standard search biomedical engines were used for seeking the papers. The use of dietary supplements such as minerals, vitamins and antioxidants has an essential role in the prevention and treatment of varicocele by increasing the levels of antioxidant enzymes (e.g. peroxidase, superoxide dismutase and catalase) and decreasing the levels of inflammatory markers (e.g. tumour necrosis factor-α, interleukin-6 and interleukin-1) in testis. According to the results, the dietary supplements may alleviate the spermatogenesis in varicocele patients through different mechanisms such as suppression of stress oxidative and inflammation in testicular tissue.
