Correlations between Polymorphisms of Estrogen 1, Vitamin D Receptors and Hormonal Profile in Infertile Men
Acta Endo (Buc) 2016, 12 (2): 137-144doi: 10.4183/aeb.2016.137
Objective. Estrogen receptor alpha (ESR1) polymorphisms (XbaI and PvuII) and vitamin D receptor (VDR) polymorphisms (FokI, BsmI, ApaI and TaqI) are the most frequently studied regarding the correlations with the infertility in males, but the results are controversial. The purpose of this study is to evaluate possible correlations between hormonal markers, VDR and ESR1 genotypes and semen analysis, in order to bring new data for a better understanding of male infertility. Subjects and Methods. 42 infertile men and 28 controls were enrolled. The polymorphisms of VDR gene (ApaI, TaqI, BsmI and FokI) and ESR1 (XbaI and PvuII) were performed by PCR-RFLP, along with hormonal markers. Results. An important correlation between PvuII polymorphism and infertility status was revealed. A significant difference between control and infertility group regarding the presence of BsmI (A>G) and ApaI (G>T) polymorphisms was observed in infertile group, prolactin and DHEA were found to correlate significantly statistic with BsmI GG genotype, whereas ApaI AA genotype correlates with prolactin and SHBG levels. Conclusions. By a multivariate analysis, we demonstrated a cumulative effect of some genetic variants in the hormonal status of infertile patients. Therefore, we show that specific genetic variants of ESR1 and VDR genes may jointly influence human spermatogenesis.
Keywords: ESR1 polymorphism, VDR polymorphism, men infertility.
