Background: Cigarette smoking is associated with impairment of testicular function. Nicotine is a major component of cigarette smoke.In the present study we aimed to study the effect of administration of nicotine-melatonin on sperm parameters in adult mouse. Materials and Methods: Male NMRI mice were divided into 4 groups: 1) control(normal saline) group 2) nicotine treated group 3) melatonin t...
Objectives: The aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (MDA) production in mice. Materials and Methods: Thirty-two adult male NMRI mice weighing 30±2 g were used. All the animals were divided into 4 groups. Control group: received saline 0.1 ml/mouse/day orally for 30 days. Royal Jelly group (RJ): re...
Background: It is shown that hypertension may affect androgens. The role of blood pressure on sperm parameters is matter of debate. The main goal was to evaluate the probable association between systolic and diastolic blood pressure and sperm parameters. Materials and Methods: Semen Sample of men (aged: 27- 45 years old) from 40 infertile cases who attended at Yazd research and clinical center ...
Background: Several studies have reported that cigarette smoking affects sperm parameters, especially semen quality, but their results are contradictory. Objective: This retrospective study aims to evaluate the relationship of sperm parameters with smoking in men with idiopathic infertility. Materials and Methods: This retrospective study was conducted on 1744 infertile men with at least on...
The present study to investigate that the correlation between sperm parameters and sperm DNA fragmentation in fertile and infertile cigarette smoking patient. Forty men undergoing infertility evaluation were divided into four groups according their smoking ability (A: 2 days ( n=10), B: 4 days ( n=10), C: 8 days ( n=10), D: 15 days ( n=10)) sperm parameters ( sperm concentration, pH, Viscosity,...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
Background: Matricaria chamomilla (chamomile) is a herb used to treat various human illnesses. The present study was conducted to investigate the effects of chamomile extract on spermatozoon quality, serum levels of estradiol and testosterone, and sperm tail length in male adult rat. Methods: Male Sprague-Dawley rats received extract of chamomile (400 mg/kg once daily, orally) during an 8-week...
Background: Formaldehyde is widely used in industry and in medicine as tissue fixative and disinfectant. It contains reactive molecules which have been known for its cytotoxic effects. In the present study, the probable protective properties of Rosa damacena aquatic extract, against the harmful effects of formaldehyde was evaluated by consideration of sperm count, motility, viability, morpholog...
Background & Aims: Reactive oxygen species (ROS) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. a-tocopherol is known as an effective antioxidant against oxidative stress. The aim of this study was to evaluate the antioxidant effects of a-tocopherol on count, motility, viability, TAC capacity, and DNA integrity rat spermatozoa during semen f...
