چکیده

BACKGROUND Bisphenol A (BPA) is a synthetic chemical widely used in the production of polycarbonate plastic and epoxy resins found in numerous consumer products. In experimental animals, BPA increases embryo implantation failure and reduces litter size. OBJECTIVE We evaluated the association of urinary BPA concentrations with implantation failure among women undergoing in vitro fertilization (IVF). METHODS We used online solid phase extraction-high performance liquid chromatography-isotope dilution tandem mass spectrometry to measure urinary BPA concentrations in 137 women in a prospective cohort study among women undergoing IVF at the Massachusetts General Hospital Fertility Center in Boston, Massachusetts. We used logistic regression to evaluate the association of cycle-specific urinary BPA concentrations with implantation failure, accounting for correlation among multiple IVF cycles in the same woman using generalized estimating equations. Implantation failure was defined as a negative serum β-human chorionic gonadotropin test (β-hCG < 6 IU/L) 17 days after egg retrieval. RESULTS Among 137 women undergoing 180 IVF cycles, urinary BPA concentrations had a geometric mean (SD) of 1.53 (2.22) µg/L. Overall, 42% (n = 75) of the IVF cycles resulted in implantation failure. In adjusted models, there was an increased odds of implantation failure with higher quartiles of urinary BPA concentrations {odds ratio (OR) 1.02 [95% confidence interval (CI): 0.35, 2.95}, 1.60 (95% CI: 0.70, 3.78), and 2.11 (95% CI: 0.84, 5.31) for quartiles 2, 3, and 4, respectively, compared with the lowest quartile (p-trend = 0.06). CONCLUSION There was a positive linear dose-response association between BPA urinary concentrations and implantation failure.

Effects of bisphenol-S low concentrations on oxidative stress status and in vitro fertilization potential in mature female mice

Bisphenol-S (BPS) is a new bisphenol-A substitute widely used in many plastic products. Bisphenol-A as a main member of bisphenol family has been known as an endocrine system disrupter chemical compound. Like other members of bisphenol family, there is public health concern about the toxic effects of BPS on reproductive system, thus, we examined BPS effects on in vitro fertilization (I...

Paternal Urinary Concentrations of Parabens and Other Phenols in Relation to Reproductive Outcomes among Couples from a Fertility Clinic

BACKGROUND Human exposure to phenols, including bisphenol A and parabens, is widespread. Evidence suggests that paternal exposure to environmental chemicals may adversely affect reproductive outcomes. OBJECTIVES We evaluated associations of paternal phenol urinary concentrations with fertilization rate, embryo quality, implantation, and live birth. METHODS Male-female couples who underwent ...

P-102: Recurrent In Vitro Fertilization Failure and Hereditary Thrombophilia

a:4:{s:10:"Background";s:363:"The largest percentage of failed in vitro fertilization (IVF) cycles are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure. The aim of this case-control study was to determine whether or not hereditary thrombophilia is more prevalent in women with recurrent IVF failures.";s:19:"Ma...

Association of estrogen receptor 1 rs9340799 polymorphism with implantation failure in Iranian infertile women

  Purpose: Estrogen as a crucial hormone during pregnancy acts by two types of receptors.   Estrogen receptor alpha, expressed by estrogen receptor 1 (ESR1) gene, is more abundant and   exists in all human reproductive systems. Association of ESR1 gene polymorphism has been   shown in some reproductive fields such as spontaneous abortion, endometriosis-related infertility   and in vitro fertili...

Association between MTHFR 1298A>C Polymorphism with RSA and IVF Failure

Abstract Background Polymorphism A1298C of the methylenetetrahydrofolate-reductase (MTHFR) gene has been implicated in spontaneous abortion. In this study, we determined the allele and genotype frequencies of this polymorphism in recurrent spontaneous abortion (RSA) and implantation failure after in vitro fertilization (IVF). Materials and Methods We performed a case–control study on 60 wom...
