Low androgen secretion in men may be caused by poor lifestyle, testicular pathology, etc. Patients can be treated by improving lifestyle and using medications such as testosterone undecanoate as prescribed by the doctor. 1. Improve lifestyle: Anxiety and depression, lack of exercise, unhealthy diet, etc. may impair the function of testicular hormone secretion, which may lead to decreased secretion of androgen. Patients can improve by strengthening exercise, eating a balanced diet and maintaining a good mood. 2. Testicular lesions: lesions of testis itself may lead to low testicular function, unable to secrete enough androgen. Exogenous androgen can be taken orally as prescribed by the doctor, and common drugs include testosterone undecanoate, methyltestosterone and so on. Patients need to find out the cause of the disease under the guidance of a physician to carry out targeted treatment, follow the doctor’s instructions to use drugs, not to take their own medication or the use of prescriptions.
