Quality of fresh and cryopreserved bovine sperm is reduced by BPA and BPF exposure
Reproduction and Fertility, 2023 Bisphenol A (BPA) is an endocrine-disrupting compound, used as the key monomer of polycarbonate plastics and epoxy resins. BPA has been detected in both humans and farm animals and has been correlated with decreased sperm counts and motility. BPS and BPF

Modulation of fetoplacental growth, development and reproductive function by endocrine disrupters
Frontiers in Endocrinology, 2023 Maternal endocrine homeostasis is vital to a successful pregnancy, regulated by several hormones such as human chorionic gonadotropin, estrogen, leptin, glucocorticoid, insulin, prostaglandin, and others.

Estrogenic effects of several BPA analogs in the developing zebrafish brain
Frontiers in Neuroscience, 2016 Important set of studies have demonstrated the endocrine disrupting activity of Bisphenol A (BPA). The present work aimed at defining estrogenic-like activity of several BPA structural analogs, including BPS, BPF, BPAF, and BPAP, on 4-day or 7-day post ...

Oral Systemic Bioavailability of Bisphenol A and Bisphenol S in Pigs [PDF]
Environmental Health Perspectives, 2019 Given its hormonal activity, bisphenol S (BPS) as a substitute for bisphenol A (BPA) could actually increase the risk of endocrine disruption if its toxicokinetic (TK) properties, namely its oral availability and systemic persistency, were higher than those of BPA.The TK behavior of BPA and BPS was investigated by administering the two compounds by ...

4,4′-(((Perfluoropropane-2,2-diyl)bis(4,1-phenylene))bis(oxy))-bis(2,3,5,6-tetrafluoropyridine)
Molbank, 2023 The title compound was synthesized in near-quantitative yield using nucleophilic aromatic substitution of 4,4′-(hexafluoroisopropylidene)diphenol (BPAF) with perfluoropyridine (PFP). The purity and structure were determined by NMR (1H, 13C, 19F), GC–EIMS,

Comment on “Toxicokinetics of bisphenol A, bisphenol S, and bisphenol F in a pregnancy sheep model”
Chemosphere, 2019 Gingrich et al. (2019) report a comparative toxicokinetic (TK) study of Bisphenol A (BPA), Bisphenol S (BPS) and Bisphenol F (BPF) in the pregnant ewe model after a single subcutaneous administration of BPS or a mixture of BPA, BPS and BPF. The topic is highly relevant. Unfortunately, many errors were noted in the calculation of TK parameters.
