“…In that study, Rudick et al [71] found no significant differences between vitamin D levels and ovarian stimulation parameters, fertilization rates, embryo quality markers, or number of embryos transferred. CP rates decreased with worsening vitamin D status, from 74 % in replete recipients to 35 % in recipients who were vitamin D deficient (p=0.002).…”

“…A societal perspective was employed and only estimated direct costs were considered. Vitamin D deficiency was defined as <20 ng/mL in accordance with the Endocrine Society guidelines [7], and also consistent with the definition utilized by the majority the trials included in this review [67][68][69][70][71][72]. The study by Polyzos et al [73] was selected for utilization of clinical pregnancy and ongoing pregnancy rates for mathematical modeling secondary to reporting the largest cohort, recency of publication and attempting to control for embryo quality and quantity by including single blastocyst ART cycles only.…”

“…A follow-up study examining the relationship between recipient vitamin D levels and pregnancy rates in donorrecipient ART cycles was subsequently performed to test this hypothesis [71]. In that study, Rudick et al [71] found no significant differences between vitamin D levels and ovarian stimulation parameters, fertilization rates, embryo quality markers, or number of embryos transferred.…”

Purpose To review the current literature regarding the role of vitamin D status in pregnancy outcomes in women undergoing assisted reproductive technology (ART) and to assess cost-effectiveness of routine vitamin D deficiency screening and repletion prior to initiation of ART.Methods A systematic literature review was conducted using PubMed. Relevant study outcomes were compared among the selected studies. A cost-benefit analysis was performed using a decision tree mathematical model with sensitivity analyses from the perspective of direct societal cost. Published data were used to estimate probabilities and costs in 2014 US dollars. Results Thirty-four articles were retrieved, of which eight met inclusion criteria. One study demonstrated a negative relationship between vitamin D status and ART outcomes, while two studies showed no association. The remaining five studies concluded that ART outcomes improved after vitamin D repletion. Conclusion The majority of reviewed studies reported a decrement in ART outcomes in patients with vitamin D deficiency. Cost-benefit analyses suggested that screening and supplementing vitamin D prior to ART might be cost effective, but further evidence is needed. Given the absence of Level I evidence regarding vitamin D status and ART outcomes, full endorsement of routine vitamin D screening and supplementation prior to ART is premature.

“…In a cross sectional study of infertile women undergoing IVF, we had previously identified significantly higher levels of 25-hydroxyvitamin D (25OHD), a metabolite that reliably reflects the overall vitamin D status, in the follicular fluid of women achieving clinical pregnancy following IVF [23]. While this latter observation was recently corroborated by others [24], including in donor egg recipients [25], data relating vitamin D status to IVF outcome remain far from unequivocal [26].…”

Purpose Environmental influences on reproductive success are recognized. We hypothesized that location of fertility clinics may influence treatment success and explored this hypothesis utilizing donor egg IVF (IVF) embryo transfer (ET) model. Methods Publicly accessible national registry data (Society for Assisted Reproductive Technology) on fresh & frozen (FET) ET cycles undertaken at participating clinics across North America (n=444 IVF centers) for 2007 were utilized. Information on number of donor egg IVF cycles, live birth (LB) rate following fresh and frozen ET(FET), average number (#) of ET and IVF center's location, geographical coordinates (latitude, longitude, altitude), annualized average temperatures and midyear regional ultraviolet B (UVB) radiation intensity were obtained. Multivariable logistic regression analyses assessed relationship between LBR (in tertile and uppermost versus lesser quartiles) following fresh and FET with geographical coordinates (region and altitude of clinic location) and ecological influences (average temperature and midyear UVB intensity), adjusting for #ET and clinic experience with donor egg IVF. Results Average number of fresh ET, clinic location (region) and midyear UVB intensity were positive predictors of LBR following fresh ET, whereas altitude and annualized average regional temperature demonstrated an inverse relationship with LBR following fresh ET. For FET cycles, #ET, clinic region and altitude were positive determinants of increasing LBR's. Annualized regional temperature and midyear UVB failed to demonstrate any relationship with LB following donor egg FET. Conclusion Our data suggest that ecological influences may relate to donor egg IVF cycle success. Future studies are needed to better elucidate the mechanisms that could explain the observed associations.

Background Recently, the relationship between nutrition and reproduction is being studied. In particular, when older women receive reproductive treatment, egg aging causes greater problems than organic factors. Methods This study investigated the relationship between nutrition and reproduction with a focus on factors that cause aging, including oxidation, glycation, and chronic inflammation. A large volume of data concerning each nutrient's relationship with reproductive medicine was collected from a number of observational studies. Main findings The results showed that refined carbohydrates should be avoided and care should be taken to achieve proper intake of omega‐3 fatty acids. Folic acid and vitamin D were also effective. For men, antioxidant measures are especially effective. The effects of antioxidants are related to insulin resistance, which causes chronic inflammation. Conclusion Recent research has shown that rather than meal content, meal intervals are more important for improving insulin resistance. Future research should examine lifestyle‐related nutrition factors and their relationships to reproductive treatment.
