introduction: cyclophosphamide (cp) is used for the treatment of various cancers. in spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. in the current study, we have investigated the adverse effects of cp on morphology and histology of testis rats. metho...
backgroud: intrauterine insemination (iui) is generally attempted before proceeding to more expensive and invasive assisted reproductive techniques such as invitro fertilization (ivf) and intracytoplasmic sperm injection (icsi). this procedure is most commonly performed as a therapeutic method for couples with a wide variety of subfertility etiologies, such as low count or low motility of sperm...
Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...
Introduction & Objective: Melatonin, the most important secretary hormone of pineal gland, as a powerful antioxidant has a high potent for neutralizing the toxicity of drugs. In the present study we aimed to demonstrate the effect of melatonin on testicular damage and sperm parameters deficiency induced by acetylsalicylic acid, in adult male mice. Materials & Methods: Male NMRI mice were div...

Purpose: The purpose of this study is to evaluate the effect of Di-(2-ethylhexyl) phthalate (DEHP) on testicular spermatid number per gram testis (TSN), daily sperm production (DSP), count, motility, viability, morphology, and chromatine quality of epididymal sperm. Materials and Methods: The protocol for DEHP administration was that adult male NMRI mice (the age group of 4 weeks) received 29 D...
In the present study phosphatase levels ( Acid and Alkaline ) were compared with sperm count and motility in 100 subjects with varying conditions. All the subjects presented were between 21-45 years of age. Samples of semen were collected from 100 cases comprising of the different grades of sperm concentration and motility. Human seminal fluid contains significant amount of acid phosphatase and...
Introduction: Spinal cord injury (SCI) is a serious public health problem which seriously affects the victim, family, and even the society. Research studies have shown that 80% of SCI victims are men. In recent years, there have been extensive research works on the effect of SCI (acute and/or chronic) on fertility potential of sperm and spermatogenesis in laboratory animals. SCI may disturb the...
BACKGROUND We seek to determine whether dietary and supplement intake of specific micronutrients (zinc and folate) and antioxidants (vitamins C, E and beta-carotene) is associated with semen quality. METHODS Ninety-seven healthy, non-smoking men provided semen and were interviewed. Average daily nutrient intake from food and supplements was derived from a self-administered food frequency ques...
Background: Wi-Fi allows electronic devices such as laptops to exchange data or connect to a network resource. The main goal of this study was to assess the bioeffects of short term exposure to 2.4 GHz microwave radiation emitted from a common Wi-Fi router on sperm quality. Materials and Methods: Male Wistar rats were divided into 7 groups; I, sham exposed 4 h/day for 7days at 30 cm from ...
