Having low T and E is not healthy for various reasons (increased ageing, low energy, depression, bad skin/teeth, osteoporosis, cognitive problems, insomnia, hot flushes, etc), why aren't you supplementing with any E? Also, MPA is personally not my preferred progestogen for reasons that I mentioned here several times, especially given the bio-identical form is available and if spiro alone cannot reduce T enough (it also blocks T, by the way which no test can measure), E can help further reduce T and there is also an anti-androgen called bicalutamide which (only) blocks T quite effectively even at very low doses.
Just ideas for you to share with your doctor, I'm not one, not pretending to be one but have much experience with hormones. 😉 Best of luck. 🙂
