Weakness of ejaculation is mainly caused by factors such as decreased secretion of testosterone, reproductive system diseases, frequent sex life and mental stress. 1. Decrease in testosterone secretion: The decrease in testosterone secretion caused by age or disease factors and the decrease in ejaculatory nerve reflexes may lead to weak ejaculation. 2. Reproductive system diseases: If the patient has prostatitis, urethritis, urethral injury and other reproductive system diseases, ejaculatory weakness may occur. 3. Frequent sex life: If sex life is too frequent, leading to a decline in sperm quality and quantity, it is also easy to have weak ejaculation. 4. Mental factors: patients with high mental stress and poor mood may also experience weak ejaculation. Patients should ensure adequate nutrition, maintain regular work and rest, strengthen physical exercise, avoid excessive sex and masturbation, relieve mental stress, and maintain a relaxed mood. If you suffer from reproductive system diseases, you should treat the primary disease in time, which can help relieve the symptoms of weak ejaculation. Patients with symptoms of weak ejaculation should go to a regular hospital in time, under the guidance of the doctor, to identify the causes, targeted treatment.
