PSYCHOTIC DISORDER INDUCED BY CLOMIPHENE CITRATE IN A MAN: A RARE CASE REPORT

The clomiphene citrate is one of the selective estrogen receptor modulators and its function is to indirectly induce ovulation, stimulating the secretion of pituitary gonadotropins (follicle-stimulating hormone (FSH) and luteinizing hormone (LH)), subsequently increasing testosterone circulation levels. Its main adverse effects include increased ovarian volume, vasomotor symptoms, pelvic discomfort, and hepatic dysfunction. However, some reactions to this medication may be unknown or poorly reported in the scientific literature. Hormonal effects may be responsible for the unfavorable psychotic outcomes in conjunction with the antiestrogenic activity of clomiphene. The appearance of psychotic symptoms, especially in women with a pre-existing psychiatric history, has been previously studied [1,4]. The effects were attributed to an enhanced testosterone-androgen receptor interaction in the brain, subsequently leading to alteration of emotional conditions. Proposed neurobiological targets include catecholaminergic cells in the hypothalamus and other limbic regions of the brain.). Nevertheless, the occurrence of such symptoms has not been reported in the literature in males. This letter aims to report the case of a 36-year-old male patient who presented an adverse reaction that is not clear in the literature on Clomiphene Citrate, since the majority of reported cases are in the female population with some previous psychiatric comorbidity. The patient had a previous diagnosis of fibromyalgia. Approximately 20 days after the introduction of the medication, he presented his first psychotic episode with manifest characteristics, with increased energy, hypersexualization, low need for sleep, grandiose delusions, impulsive and inappropriate behavior lasting an average of 4 days. The patient's family reported that he had never exhibited similar behavior. The second psychotic episode occurred approximately 20 days after the first. In the latter, the patient presented with persecutory delusions, risky behavior, paranoid behavior, risk of self- and hetero-aggression, and was taken to his first psychiatric hospitalization. It was reported that he used clomiphene citrate up to 15 days before psychiatric hospitalization. The use of other psychoactive substances was also ruled out (a toxicological test with a negative result) and admission and neuroimaging exams (magnetic resonance imaging of the skull) were carried out, with all results within normal limits. The patient was
