Male hypogonadism is a medical condition associated with disorders of sperm production or testicular hormone function. Endocrine disorders related to a deficiency in testosterone secretion can lead to various systemic complications, which can be alleviated by appropriate hormone supplementation. The key to successful treatment lies in an accurate diagnosis based on thorough diagnostic procedures. Studies have shown that testosterone supplementation provides real benefits only for patients with genuine hypogonadism. During the diagnostic process, it is also necessary to exclude secondary causes of hypogonadism. In Poland, healthcare professionals have access not only to various testosterone preparations but also to medications that act on the gonadotropic axis. These individually dosed treatments allow for therapeutic success. The widespread availability of laboratory tests and literature (not always of a professional nature) may encourage patients to self-diagnose and self-administer subjective hypogonadism treatment, leading to numerous complications. Doctors should alert patients to this potential issue and refer them to specialists to ensure that such therapy is conducted according to medical indications and with patient safety in mind.
