Semen stickiness is related to ejaculation frequency, and ejaculation difficulty is related to infectious lesions, urinary tract obstruction, and poor physical condition. 1. Sticky semen: If the patient lacks sexual life in daily life and the frequency of ejaculation is relatively low, the semen may be sticky. After more frequent intercourse, the semen may be relatively thin. 2. Infectious lesions: If the patient has urethritis, cystitis, prostatitis, epididymitis and other conditions, it may be difficult to ejaculate. At the same time, it is often accompanied by frequent urination, urinary urgency, urinary pain and other manifestations. 3. Urinary tract obstruction: if the patient has urethral foreign body, urethral stone, urethral scar, etc., and the urethra is not smooth, the symptoms of ejaculation difficulty may occur. 4. Poor physical condition: If the patient has recent physical fatigue, mental deficiency, or the existence of diabetes and other pathological conditions, resulting in poor physical condition, may also have ejaculation difficulties. If the patient is not feeling well, he should consult the doctor for examination and early treatment.
