background: a bulk of contraceptives on the market is women-oriented today. the aim of this study was to investigate the effect of a medicinal herb, acacia nilotica on various parameters of male fertility using a rat model. methods: male wistar rats (n=40) were randomly divided in to two groups. one group received acacia nilotica, while the other acted as controls. ten animals from each group w...

The effects of sauna exposure on sperm movement characteristics and other semen parameters were evaluated using computer-assisted sperm analysis (CASA). A significant (p < 0.01) decrease in average path velocity (VAP), curvilinear velocity (VCL) and amplitude of lateral head displacement (ALH) was found after exposure to sauna for 2 weeks. The altered parameters returned to their original value...

Background: The fertilizing sperm potential is directly related to its mitochondria activity evaluated by measuring the mitochondrial membrane potential (ΔΨm). The objectives of the present study were to investigate the vitality and mitochondrial membrane potential of sperm in infertile men by the and to assess the correlations between sperm parameters and the level of sperm mitochondrial membr...

Objective: Using correlation analysis between the sperm spontaneous acrosome reaction rate (SARR) and routine semen parameters in male infertility patients, we explored the value of the sperm spontaneous acrosome reaction in the evaluation of sperm functions. Methods: The participants comprised of 219 male infertility patients who had visited the Center for Reproductive Medicine, Shandong Unive...

Background: The main object of this study was to determine the frequency of occupational categories of men who attended an infertility clinic, and to evaluate the differences in the semen quality parameters among occupational categories. Materials and Methods: This cross-sectional study was conducted on men who attended the Infertility Clinic of Royan Institute, located in Tehran, Iran. The stu...

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: Iron oxide nanoparticles are commonly used for various purposes, such as biomedical, medical, and cosmetic services and research. However, there is a little information about the effects of the nanoparticles on human health. The current investigation was conducted to evaluate the adverse effects of iron oxide nanoparticles (FeNP) on the reproductive organs of mice, such as the testi...

Polychlorinated biphenyls (PCBs) are common environmental contaminants that represent a considerable risk to reproductive toxicity in exposed human populations. Although some experimental studies have suggested an association between the levels of PCBs and semen quality, the direct effects of PCBs on human sperm parameters remain largely unexplored. To this aim, a short-term in vitro incubation...

This study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. After incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. There was a significant (P

BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the risk factors of impaired male fertility potential. Studies have investigated the effect of CP/CPPS on several semen parameters but have shown inconsistent results. Hence, we performed a systematic literature review and meta-analysis to assess the association between CP/CPPS and basic semen parameters in adult me...
