BACKGROUND di (2-ethylhexyl) phthalate (DEHP) is widely used in the plastic industry and can induce reproductive toxicity. On the other hand, L-carnitine (LC) plays a crucial role in sperm metabolism and maturation. This study evaluates the effect of LC on body and testis weight, testis tissue, count, motility, viability, morphology, and chromatin quality of epididymal sperm, testicular spermat...
Despite of many benefits of nanoparticles induced, their increasing usage raises concern about the consequences and health threats that it might bring to humans. So, the current study evaluated the testicular defects after i.p. injection of silver naoparticles (AgNPs). Male mice, weighing 31-34 g, and of 3 months old were randomly assigned into three groups with respect to concentration of nano...
Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...
This study was conducted to determine a possible relationship between regular cell phone use and different human semen attributes. The history-taking of men in our university clinic was supplemented with questions concerning cell phone use habits, including possession, daily standby position and daily transmission times. Semen analyses were performed by conventional methods. Statistics were cal...
Background: Arsenic as a heavy metal exerts malformation and changes in the reproductive system of men via induction of oxidative stress. We sought to investigate the impact of Vitamin C (Vit C), as a potent antioxidant, on sperm quality and testicular tissue in mice that received sodium arsenite. Methods and materials: NMRI mice were classified into four groups: control, sodium arsenite (7 mg...
Purpose: The Increase of oxidative stress production a causes after oxygen free radicals one of the factors involved in male infertility. In this study the role of leptin in product reactive oxygen species in seminal plasma in adult rat were evaluated. Materials and Methods: Sixty-five male rats were randomly divided into four groups. The control group receives normal saline and other animal, i...
cyclophosphamide (cp) is one of the anti-neoplastic drugs. despite its numerous clinical applications, it has devastating effects on the testicles and declines the sperm quality in treated patients. this study was aimed to investigate the protective effect of crocin in improving the toxicity induced by cp in reproductive system. in this study, 24 male adult mice (6 to 8 weeks) were randomly div...
Objective Metals can cause male infertility through affection of spermatogenesis and sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is mediated via various mechanisms such as production of reactive oxygen species (ROS). Flavonoids have antioxidant and metal chelating properties which make them suitable candidates for neutralizing adverse effects of metals ...
The objective of the study was to characterize body growth, testicular development, and puberty from 8 to 14 mo of age in bulls (n = 120) produced by mating sires from Hereford, Angus, Norwegian Red, Swedish Red and White, Friesian, and Wagyu breeds to MARC III ((1/4) Hereford, (1/4) Angus, (1/4) Red Poll, and (1/4) Pinzgauer) cows. Traits evaluated were birth weight, weaning weight (at 215 d),...
