Background and purpose: About 50% of infertility in couples is related to male factors and oxidative stress is one of the main causes of infertility in men. Hydrogen peroxide has an adverse effect on male reproductive system due to its free radicals. Spirulina and phycocyanin are known to have antioxidant properties and can modify stressors. Materials and methods: In this experimental study, ...
Virilisation of the XX foetus is the result of androgen excess, resulting most frequently from congenital adrenal hyperplasia in individuals with typical ovarian differentiation. In rare cases, 46,XX gonads may differentiate into testes, a condition known as 46,XX testicular disorders of sex development (DSD), or give rise to the coexistence of ovarian and testicular tissue, a condition known a...
abstract background: in this study we aimed to evaluate the impact of chronic exposure to the gly-phosate (gp) on rat’s testicular tissue and sperm parameters. objective: testicular tissue, morphology of sperms and testosterone level in serum of mature male rats were analyzed. materials and methods: animals were divided into two test and control-sham groups. the test group was subdivided into 4...
background: atrazine (atr) is used as an agriculture herbicide worldwide. it has been shown that atr adversely affect the reproductive system in rodents. in this study we aimed to evaluate the impact of chronic exposure to atrazine (atr) on male testicular tissue, sperm parameters, serum level of total thiol molecules (ttm) and malodialdehyde (mda) content of testes. methods: to follow-up this ...
BACKGROUND Spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (SSCs) in testis tissue and during the culture; therefore we undertook this study ...
We present a quantitative near-IR spectroscopy study of the absolute values of oxygen saturation of hemoglobin before and after surgically induced testicular torsion in adult rabbits. Unilateral testicular torsions (0, 540, or 720 deg) on experimental testes and contralateral sham surgery on control testes are performed in four adult rabbits. A specially designed optical probe for measurements ...
Background and Aim: Methylphenidate (MPH) is one of the commonly used drugs in the treatment of hyperactivity disorder in children. The use of MPH has been associated with increased activity of the central nervous system so may lead to the abuse of this compound. Nicotine is one of the compounds available in a wide range of people in various forms. The negative effects of nicotine on pituitary-...
Abstract Introduction: Researchers usually search for medications of infertility. Hence, this study was done to determine the effects of L-Carnitine and exercise on histological changes of testicular tissue after Boldenone steroid use in male rats. Objective: Assessment of the effects of L-Carnitine with Endurance training after Boldenone use on testicular tissue changes in male rats. Materi...
Recent work in preservation of female fertility as well as new information on the nature of spermatogonial stem cells has prompted an investigation into the possibility of an effective clinical-grade procedure for the cryopreservation of testicular cells and/or tissue. Clinical-grade reagents, validated equipment, and protocols consistent with cGTP/cGMP standards were used in developing a proce...
background: diabetes mellitus has a variety of structural and functional effects on the male reproductive system. diabetes results in reduced sperm parameters and libido. the present study aims to investigate the effects of royal jelly (rj) on reproductive parameters of testosterone and malondialdehyde (mda) production in diabetic rats. materials and methods: this experimental study was conduct...
