Hi, and thanks for your medical question on eHealth forum!
If your ovaries have been removed at such a young age, then most gynecologist would recommend HRT to tide over the side effects of low estrogen such as osteoporosis, hot flashes, depression, and increased risk of cardiovascular diseases. Since HRT replaces body hormones, the side effects outweigh the benefits. Please consult your gynecologist regarding this. Hope this helps. Take care!
