This condition is called Surgical Menopause
. Removal of ovaries commonly leads to decreased libido as a side effect.
This happens due to deficiency of hormones like Testosterone
production which normally occurs from the ovaries.
She may need hormone replacement therapy
for this, but that can be decided upon only after ruling out other causes of decreased interest in sex.
This can be done by consulting a Gynecologist or Endocrinologist
Hormone replacement therapy has side effects like acne, facial hair and excess anger. It has to be decided by the doctor examining her regarding the best possible treatment for her.
