The purpose of the present invention is to prepare a powder preparation for nasal administration that includes, as an active ingredient, a particulate steroid hormone having an average particle size of 50–300μm. The powder preparation for nasal administration may further include a water-soluble polymer (in particular, a water-soluble polysaccharide such as cellulose comprising a hydroxyalkyl group). The particulate steroid hormone may be formed from testosterone and/or a derivative thereof. The water-soluble polymer may be particulate. The proportion of the water-soluble polymer may be around 1–50 parts by weight with respect to 1 part by weight of the particulate steroid hormone. This powder preparation for nasal administration may be configured such that the Cmax of the steroid hormone component can be adjusted to be 15ng/ml or less. The powder preparation for nasal administration enables the concentration of a steroid hormone such as testosterone in the blood to be constrained to a specific range over a long period of time.
