OBJECTIVES To evaluate the presence of hormonal abnormalities and fertility disorders in patients with chronic kidney disease (CKD) awaiting renal transplantation. METHODS From September 2009 to April 2011 all male patients with CKD awaiting kidney transplantation were investigated. The following tests were performed: semen analysis, serum concentration of testosterone, SHBG, LH, FSH and prol...

INTRODUCTION Somatic chromosomal rearrangements that occur in infertile males are thought to be one of the major genetic factors influencing male infertility. The objective of this retrospective study was to evaluate sperm parameters in a group of patients with balanced translocations. MATERIAL AND METHODS We analyzed semen of 84 balanced somatic translocation carriers [35 Robertsonian transl...

OBJECTIVE The objective of this study is to estimate the effects of Inclear, a feminine cleanser, on sperm motility. METHODS Semen samples were obtained from infertile male patients. Following liquefaction, the raw semen samples were diluted with Ham's F-10 nutrient mixture medium containing 0.4% human serum albumin solution at a ratio of 1:3. The semen samples were subsequently centrifuged t...

To investigate a possible common environmental exposure that may partially explain the observed decrease in human semen quality, we correlated seminal plasma and blood cadmium levels with sperm concentration and sperm motility. We studied three separate human populations: [Group 1] infertility patients (Long Island, NY), [Group 2] artificial insemination (AI) donors (Rochester, NY), and [Group ...

Several studies have been conducted in an attempt to determine the optimal freezing rate for cryopreservation of striped bass (Morone saxatilis) sperm. In this study, the effects of freezing rate (-10 °C, -15 °C, -20 °C, and -40 °C/min) on gamete quality was examined, using Sybr-14 and propidium iodide to determine viability (sperm cell membrane integrity), ATP concentration using a luciferin-l...

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...

background: the trace element copper has been identified as a highly toxic element for sperm. it is known to affect sperm motility in humans and experimental implantation of copper in the epididymis vas deferens and scrotum of mammals has been demonstrated to affect fertility detrimentally. objective: sperm concentration motility vitality and morphology are parameters used to evaluate potential...

Background Background: The fatty acid composition of the sperm membrane changes drastically during spermatogenesis and may be key to its function. Previous data has shown that intake of long chain poly-unsaturated fatty acids can change the fatty acid composition of tissues, including testes and sperm. However, whether these changes in composition translate into changes in semen quality or male...
