Inositol (me8oinositol or myoinositol) occurs very widely in plants, animals and micro-organisms (Fleury & Balatre, 1947; Courtois, 1951; Hawthorne & Chargaff, 1954; Mann, 1954a). It occurs in the free state as well as in the form of inositol phosphatides, while in plants it is often present as the hexaphosphate, phytic acid. Treatment of liver and nervous tissue by the standard procedure of Sc...

NAD+-dependent Isocitrate Dehydrogenase (NAD+-IDH) could be one of the cell phone radiation targets. Enzyme activity alteration may lead to decline in sperm motility during radio-frequency electromagnetic waves (RF-EMW) exposure. The current case control study aimed to investigate the possible relationship between mitochondrial NAD+-IDH activity in human seminal plasma and sperm motility among ...

Abnormal reactive oxygen species (ROS) production is associated with defective sperm function. Superoxide dismutase (SOD) is related with the scavenging of seminal ROS. We aimed to determine the effect of SOD activities of spermatozoa and seminal plasma on sperm quality. Semen samples from infertile couples who consented to the analyses were divided into two groups: 1) normospermia (n = 20); an...

The Zn and Pb concentration was determined in 45 samples of bull semen from three Artificial Insemination Stations (A,B,C) differing in degree of environmental pollution. Bull semen was diluted with Biociphos-Plus to such an extent as to obtain 16 million sperm cells in an insemination dose. The research aimed at assessing the correlation between zinc, lead and other parameters influencing the ...

Lead is one of the industrially heavy metals that caused adverse effects on male reproductive system among battery factory workers, but information on the possible impact of lead on the structural integrity of sperm cell is limited. Thus present study was undertaken to assess the structural details of human spermatozoa of lead acid battery factory workers. Blood and semen samples were collected...

In this study, age-dependent changes of sperm quality parameters in Rutilus frisii were investigated. Also, fertilization capacity of breeders was tested using two age groups of males (3 and 4 year old breeders) and one female group (i.e. 4 year old breeders). For fertilization trials, the breeders were crossed randomly among age classes. Between the two age groups, spermatological parameters d...

Background: Defective sperm quality is a significant cause of infertility in men. It is known that nitric oxide (NO) is a highly reactive free radical gas which has a dual function, being both a cytotoxic and necessary molecule for normal sperm production. Materials and Methods: To investigate correlation between NO levels with sperm parameters, a case-control study were designed with total of ...

BACKGROUND Animal studies have shown the reproductive toxicity of a number of heavy metals. Very few human observational studies have analyzed the relationship between male reproductive function and heavy metal concentrations in diverse biological fluids. METHODS The current study assessed the associations between seminal and hormonal parameters and the concentration of the 3 most frequent he...

BACKGROUND Camelids are induced (reflex) ovulators. We have recently documented the presence of an ovulation-inducing factor (OIF) in the seminal plasma of alpacas and llamas. The objective was to test the hypothesis that OIF exerts its effect via a systemic rather than a local route and that endometrial curettage will enhance the ovulatory response to intrauterine deposition of seminal plasma ...
