So, dear women (and men, because even men's coffee intake has a detrimental effect, see below):
Caffeine is a catastrophe for your hormones! Tons of reputable studies link caffeine with impaired fertility and hormonal discord. Research e.g. shows that drinking 3 cups of coffee a day (consumed by either men or women!!) increases the risk of miscarriage by 74%. Coffee is considered equal to drinking alcohol and smoking in terms of impairing fertility. And coffee depletes the B vitamins that are so necessary for healthy ovulation and hormone balance.
Caffeine also severely affects menopausal symptoms, and takes a very heavy toll on your nervous system, adrenal glands and kidneys (your body needs 5 liters of water to balance the kidneys again after one cup of coffee).
