Taking a blocker without E will put you in menopause/andropause with all of the negative symptoms associated such as fatigue, depression, irritability, insomnia, night sweats, hot flashes, accelerated ageing (wrinkles, skin less elastic and hydrated, thinner), perhaps digestive problem and tooth problems, cognitive deficits and earlier onset of Alzheimer's, osteoporosis, increased weight gain and glucose intolerance (diabetes), etc. Some of these symptoms may never appear, some may take some time to manifest (months to years), it depends on the individual but it is not a situation I'd like to find myself in.

Yuk! E naturally reduces T, by the way, the more E, the less T.
I didn't have to present female to get hormones. That was how it was done in the old times (1970's, 1980's), maybe you need to find yourself another doctor?
