The invention relates to the veterinary field. Proposed is a method for temporary blocking sexual function in a male mammal including behavioural phenomena (search for a partner, vocalization, etc.). The method comprises administration of a pharmaceutical composition once or twice to an animal, wherein said composition comprises the following active ingredients: an α-adrenergic blocking agent, tropic to the posterior nucleus of the hypothalamus, melatonin, and a steroid with gestagenic activity. The method makes it possible, while using the minimal dose of the steroid hormone, to inhibit sexual behaviour of a male animal for the period of several weeks to half a year (depending on the length of the daytime period). The pharmaceutical composition is intended for transdermal administration during any period of the sexual cycle. The use of the drug preparation is not associated with any side effects characteristic of the drugs of this type. |
