yes this can be true anon, estrogen in both sexes is required in the proper amounts ,but much lower in men , when balances get out of whack in either sex it can cause many health related problems ,for example :breast cancer in women ,and prostate cancer in men, many poeple that start taking a hormone suppliment like dhea do not realize that dhea will convert to both estrogen and testosterone at the same time then eventualy the testosterone converts to elevated levels of dihydotestosterone (or DHT ) in both sexes this is why women that take dhea long term will start to grow facial hair , this is why hormone balance is very important in either sex .
