“…It has been shown that there is a positive correlation between levels of serum AMH and vitamin D in women in the premenopausal period (27). Serum AMH levels are 18% lower in the winter months than those in the summer months, but there is no such seasonal fluctuation seen in AMH when vitamin D deficiency is eliminated (28).…”

Infertility is one of the major health problems of our time. In fact, infertility is caused by many factors. Among these factors the effect of vitamin D levels of infertility are overlooked. The prevalence of vitamin D deficiency varies between 20% and 66.8% in different countries. In fact, vitamin D deficiency can lead to infertility both women and man. Lack of vitamin D in women with polycystic ovary syndrome in the study, uterine fibroids, as well as has been demonstrated over a relationship with a decrease in reserves. In males it has been suggested to affect sperm count and morphology. At the same time vitamin D levels may play a role in facilitating implantation. Even in studies in vitro fertilization has been shown to increase the success rate with the support of vitamin D. In this article, vitamin D deficiency and infertility issues were revised in light of the current articles.

“…20 Methods employing gas chromatography (GC) in conjunction with mass spectrometry detection and recently liquid chromatography (LC)-tandem mass spectrometry with on-line solid phase extraction have been proposed as reference methods. 21,22 Despite their high accuracy and precision, these methods cannot be routinely used in either diagnostic or community research laboratories because of their complexity and low throughput. 23 Harmonization of 25(OH)D assay results may potentially improve the agreement among different methods and laboratories.…”

“…Methods for the quantification of vitamin D metabolites, mainly 25OH‐D3 and 25OH‐D2, are increasingly being switched from immunoassays (IAs) and radioimmunoassays (RIAs) to liquid chromatography coupled to tandem mass spectrometry (LC/MS/MS) . There have been a number of studies on vitamin D metabolites which have shown that LC/MS/MS methods correlate well with results obtained from commercial RIAs .…”
