RESUMEN
INTRODUCTION: Acromegaly is a disease with various comorbidities and hypogonadism is a common comorbidity in patients with acromegaly. Herein, we aim to present our experience with clomiphene citrate in a patient with acromegaly accompanied by hypogonadism, who declined surgery. CASE REPORT: A 40-year-old male patient with impaired fasting glucose, hyperlipidemia, and psychosis and who complained of increasing tongue growth, snoring, enlargement of the hands, spacing between the teeth, and loss of libido for the last 6 years was followed up. Acromegaly was diagnosed, with high levels of insulin-like growth factor-1 (IGF-1) and a pituitary neuroendocrine tumor measuring 11 mm; the patient had concomitant hypogonadism. Lanreotide was started as the initial primary medical treatment. Clomiphene citrate was added to the patient's treatment. The patient, whose IGF-1 level was high during follow-up, did not want to use the intramuscular testosterone esters for hypogonadism. In the third month of clomiphene citrate treatment, IGF-1 normalization was achieved and the patient's total testosterone level increased. DISCUSSION: Biochemical control is not always achieved with somatostatin receptor ligands and dopamine agonists in the treatment of acromegaly. Therefore, we support the use of clomiphene citrate (CC) as a cost-effective oral add-on treatment option in selected hypogonadal acromegaly cases.
