Oophorectomy complications?

[darkswitcher]

I'm FTM and going in for hysterectomy and oophorectomy tomorrow. My surgeon says injected testosterone will counter any side effects from not having estrogen anymore (and I'm switching to topical testosterone soon, so my levels will be more constant). Has anyone else had bottom surgery and can provide insight on what might happen bone/heart-wise? Supplements? Should I just drink milk or something?

Btw I'm 21, LDL slightly high, fairly healthy otherwise.
