Is there a difference in side effects between Lupron/Zoladex and having ovaries removed?

I’m 46, and met with a surgical gynecologist on Friday about getting my fallopian tubes and ovaries out. First I met with a resident doctor who claimed the side effects were identical, but from reading this sub, I’m getting the sense that this is not true.

What has your experience been like? I’m in chemo-pause now, dreading starting Lupron shots come December but not quite ready to undergo another surgery and recovery.

Also, it seems like our ovaries still produce some testosterone and hormones post menopause so I was hoping to keep mine for later.
