few researches have been performed on the circadian rhythm of oxidants and anti-oxidants and these studies have demonstrated different results. the aim of this study was to investigate the circadian variation of mda, pc and sod in non-athlete young men. the research method of this study was semi-experimental. for this purpose, 10 non-athlete active students (mean age: 23.2±2.57 years old, heigh...

The testes secrete four hormones (anti-Müllerian hormone, insulin-like peptide 3, Inhibin B and testosterone) from two endocrine cell types. It is unknown whether anti-Müllerian hormone and insulin-like peptide 3 levels have a diurnal variation, and if so, whether they covary during the day with testosterone and InhB. Sera were obtained from 13 men at 00:00, 06:00, 09:00, 12:00, 14:00, 17:00 an...
