The high levels of oestradiol found in the HF group could be – at least in part – a consequence of the presence of high lauric acid(33), which is known to increase the activity of aromatase(4) (that converts the A ring of testosterone, dihydrotestosterone or 11b-hydroxytestosterone to oestrogens) and an active substrate to treat inflammation(34). The gene discussed is CYP19A1; the disease is hydrops fetalis.
