Evaluation included complete physical examination, past medical history, habits and lifestyle factors, two complete seminal analysis with sperm functional tests, serum levels of 25-hydroxy-vitamin D₃(25(OH)VD₃), total and free testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), sex hormone-binding globulin (SHBG), total cholesterol, homeostatic model assessment of insulin resistance (HOMA-IR) index, and karyotype. The mean concentration of 25(OH)VD₃ was significantly lower in the SAG (P < 0.001) and positively correlated with all baseline seminal parameters and total testosterone levels. In addition, serum vitamin D₃ concentration was found to be positively correlated with sperm concentration (β = 2.103; P < 0.001), total number of spermatozoa with progressive motility (β = 2.069; P = 0.003), total number of motile spermatozoa (β = 2.571; P = 0.015), and strict morphology (β = 0.056; P = 0.006), regardless of other variables. This is the first comparative study to address the issue of serum vitamin D₃ content between normozoospermic patients and those with sperm abnormalities. It clearly demonstrates a direct and positive relationship between serum vitamin D level and overall semen quality, male reproductive potential, and testosterone levels.]]> Fri 17 Jun 2022 15:25:05 AEST ]]> Reactive Oxygen Species and Their Consequences on the Structure and Function of Mammalian Spermatozoa /manager/Repository/uon:47345 Fri 13 Jan 2023 12:16:37 AEDT ]]> Oxidative damage to sperm DNA: attack and defense /manager/Repository/uon:45727 Fri 04 Nov 2022 09:52:06 AEDT ]]>
