Fujimoto et al. in an observational prospective cohort study carried out in 58 infertile female patients aged 36–40 years and 37 male partners aged 38–42 years undergoing a first IVF cycle reported a 9% decrease in the probability to retrieve a mature oocyte for a doubling of female serum BPA levels; further, in the same study a 55% decrease in the probability for fertilization was associated with a doubling in female serum BPA levels [69]. This evidence concerns the gene DST and Infertility.
