Serum 25-hidroksi vitamin E3 düzeyinin sperm parametreleri üzerine etkisi'nin değerlendirilmesi

Aim: The aim of the study was to investigate whether serum level of 25-hydroxy vitamin D3 has an impact on male factor infertility or not. Materials and Methods: This was a retrospective study which was approved by the local ethics committee of Celal Bayar University. Male partners of the infertile couples who referred to Celal Bayar University Infertility Treatment and Research Center between 10.11.2015 and 10.03.2016 were included in the study (n=100). Age, job, cigarette smoking, history of varicosele, levels of serum vitamin D, total testosterone and follicle stimulating hormone and results of the sperm analysis at the same day were recorded. SPSS-18 sattistical software programme was used for statistical calculations. Results: A total of 100 patients were divided according to the normal (13%) and abnormal (87%) semen analysis results. Level of serum vitamin D were found to be higher in the group with normal spermiogram (p=0,0001). Level of vitamin D was higher in cases with morphologically normal in semen analysis (p=0,002). The rate of motil sperms were higher in cases with normal serum D vitamin levels (p=0,008). There were no difference based on the volume, sperm count per 1 ml, total sperm count and total progressive motile sperm count between cases with normal and low levels of serum vitamin D (p>0,05). Conclusion: Deficiency of vitamin D is common in our population. Deficiency of vitamin D negatively effects the results of sperm analysis particularly in terms of morphology and motility. Key words: Infertility, sperm analysis, male factor infertility, vitamin D deficiency.
