| 1 | Serum vitamin D content is associated with semen|parameters and serum testosterone levels in men显示文摘The present study aimed to evaluate the influence of serum vitamin D levels on semen quality and testosterone levels.This is a crosssectional study conducted at Androscience,Science and Innovation Center in Andrology and High-Complex Clinical and Andrology Laboratory in Sao Paulo,Brazil,with 508 male patients,aged 18-60 years,from 2007 to 2017.Seminal parameters and serum sexual hormones were correlated with serum vitamin D concentrations in 260 men selected by strict selection criteria.Patients were divided into normozoospermic group(NZG,n=124)and a group with seminal abnormalities(SAG,n=136).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 D_(3)(25(OH)VD_(3)),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)VD_(3)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 D_(3)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 D_(3)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. | Inari M Ciccone Elaine MF Costa Juliana R Pariz Thiago A Teixeira Joel R Drevet Parviz Gharagozloo Robert J Aitken Jorge Hallak | 2021 | Asian Journal of Andrology2021，23，1： | 2 |
