STUDY QUESTION Are different dietary patterns associated with semen parameters in young men? STUDY ANSWER The consumption of a Prudent dietary pattern was significantly associated with higher progressive sperm motility and unrelated to sperm concentration and morphology. The consumption of a Western dietary pattern was unrelated to conventional semen quality parameters. WHAT IS KNOWN ALREAD...

The examination of quality of the sperm ejaculate is one of the most important steps in artificial fertilization procedure. The main aim of semen storage centres is to characterise the best semen quality for fertilization. Reliable information about sperm motility is also one the most important parameters for in vitro laboratory procedures. There exist very expensive automated methods for semen...

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. Conventional semen analysis is the routine test performed during the evaluation of a couple’s fertility status. The test is cost-effective and easy to perform and at the same time provides essential information on quantitative semen parameters such as semen volume, sperm motility, concentration, viability and morpholo...

the objective of this study was to investigate aspartate-amino-transferase (ast), γ-glutamyl-transferase(ggt), alkaline phosphatase (alp), lactate-dehydrogenase (ldh) and acid phosphatase (acp) activities andsemen parameters (volume, ph, concentration, total sperm number (tsn), progressive motility, dead sperm,total morphological defect (tmd) and hypo-osmotic swelling test (host)) in seminal pl...

BACKGROUND Sperm cell death appears to be a cause of male infertility. The objective of this study was to determine the most reliable method for the evaluation of sperm quality in semen samples during sperm preparation for IVF. METHODS Conventional analysis of semen samples was compared with several cytofluorometric methods detecting death-associated changes. Neat semen from infertile patient...

background: in previous investigations, it has been clarified that electromagnetic fields (elf) can cause some changes in cellular behavior. the aim of this prospective study was to investigate the effect of magnetic field (mf) on human sperm parameters of motility, morphology, and viability. materials and methods: semen samples were collected from 12 fertile men, and were allowed to liquefy fo...

This study set out to establish a new method, using flow cytometry, to evaluate leukocytes in semen. Ejaculates of 59 males, asymptomatic for genitourinary infections, were examined. Routine semen analyses were carried out as well as peroxidase and polymorphonuclear granulocyte-elastase detection. Leukocytes were detected combining flow cytometry and monoclonal antibodies (anti-CD45, anti-CD53)...

OBJECTIVES (i) To examine the role of apoptosis in the pathogenesis of DNA damage in semen from infertile men. (ii) To assess the effects of smoking on apoptotic markers and seminal parameters among infertile men. (iii) To assess the correlation of apoptosis with conventional semen parameters. MATERIALS AND METHODS The study was carried out on 70 men with idiopathic infertility, divided into ...

OBJECTIVE The aim of this study was to evaluate the influence of different periods of abstinence on conventional semen parameters as well as functional parameters in human semen, including mitochondrial function, chromatin packing and sperm DNA fragmentation. METHODS We recruited a cohort of 2,458 men undergoing infertility investigation. Semen analyses were performed according to WHO guideli...
