Doctor Deborah Lee, Doctor Fox Online Pharmacy discussed a 2012 study on caffeine’s effect on Asians who consumed 200 mg caffeine per day and were found to have higher levels of estrogenic.
“Over the longer term, this could be an important factor as oestrogen levels are important in medical conditions such as endometriosis, osteoporosis and breast cancer.
“This was a small observational study and there is no need at present for women to stop drinking coffee. More research is needed.”
With regards to another hormone testosterone, Doctor Lee discussed another study which found that regular consumption of coffee was found to increase total testosterone levels and reduce oestrogen levels.
“The authors suggested that caffeine may act as an aromatase inhibitor, increasing levels of luteinising hormone (LH), which stimulates the production of testosterone.”
