miraDry is FDA approved for hyperhidrosis of the underarms but can be used 'off label' in other areas like the groin at the discretion of the treating physician. If by 'groin' you mean the inguinal folds, the folds between the pubic area and the thighs, this is generally a safe area and not likely to injure vascular structures or genitalia. However, > 99% of physicians are not likely to treat areas if there is no formal FDA approval. Physicians have treated the inner thighs and back with miraDry and this is an active area of clinical research. It may be prudent for you to wait until the FDA approves the miraDry procedure for groin hyperhidrosis before you pursue it further. This promises the best possible outcome.
