| 1 | The impact of ipsilateral testicular atrophy on semen quality and sperm DNA fragmentation response to varicocele repair显示文摘Varicoceles adversely impact semen quality and sperm DNA fragmentation,which typically improve with surgical repair.Some men with varicoceles have ipsilateral testicular atrophy due to damage from the varicocele.This study assessed semen quality and the sperm DNA fragmentation index(DFI)response to varicocele repair in men with ipsilateral testicular atrophy(TA)versus men with no testicular atrophy(NTA).Semen parameter values and DFI in both groups were compared preoperatively and postoperatively.The Mann-Whitney U test and the Wilcoxon signed-rank test were used where appropriate.There were 20 men in the TA group and 121 men in the NTA group with no difference in age,varicocele grade,or preoperative semen parameter values between the two groups.The NTA group had a higher preoperative DFI than the TA group.Both groups showed improvement in semen quality postoperatively,only the TA group showed a significant improvement in DFI,whereas the NTA group showed significant improvements in several parameter values and DFI.The change from preoperative to postoperative parameter values when comparing the two groups revealed a difference in total sperm motile count and DFI,with a larger mean improvement in the NTA group than in the TA group.Both TA and NTA groups showed improved semen quality and DFI after varicocele repair,but the NTA group had more improvement than the TA group.However,only total motile count(TMC)and DFI had a significantly greater mean change in preoperative to postoperative response in the NTA group than in the TA group. | Parviz K Kavoussi Natasha Abdullah Melissa S Gilkey Caitlin Hunn G Luke Machen Shu-Hung Chen Keikhosrow M Kavoussi Amy Esqueda J David Wininger Shahryar K Kavoussi | 2021 | Asian Journal of Andrology2021，23，2： | 2 |
| 2 | 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 |
