Not only seminal plasma zinc but also other trace elements affect semen quality

Impact of Seminal Trace elements and Glutathione levels on Semen Quality of Tunisian Infertile Men

Not Only What, but Also How Matters Introducing Procedural Utility: Not Only What, but Also How Matters

People not only care about outcomes, they also value the procedures which lead to the outcomes. Procedural utility is a potentially important source of human well-being. This paper aims at introducing the concept of procedural utility into economics, and argues that it should be incorporated more widely into economic theory and empirical research. Three building blocks of a concept of procedura...

Lead level in seminal plasma may affect semen quality for men without occupational exposure to lead

BACKGROUND Infertility affects approximately 10-15% of reproductive-age couples. Poor semen quality contributes to about 25% of infertile cases. Resulting from the direct effect on testicular function or hormonal alterations, heavy metals exposure has been related to impaired semen quality. The objective of this study was to assess the level of lead in the seminal plasma in men without occupati...

Trace elements in seminal plasma of men from infertile couples

INTRODUCTION An analysis of lead, zinc, cadmium and other trace elements in semen of men from infertile couples was performed to determine the association between abnormal semen parameters and enviromental or occupational exposure to some trace metals. MATERIAL AND METHODS Presence of manganese, cobalt, nickel, copper, zinc, molybdenum, cadmium, tin and lead was measured in seminal plasma of ...

Reproductive hormones in seminal plasma; it's effect on semen quality

The aim of this study was to investigate the effect of reproductive hormones in seminal plasma on the quality of the spermatozoa in men seeking infertility treatment. Of the 383 volunteers recruited, 123 had normal sperm parameters and 260 had either a single or a combination of sperm abnormalities as per WHO criteria. Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) Prolactin (PRL)...
