Can a man expel semen through the urethra?

The male urinary and reproductive systems are connected and normally semen is excreted through the external urethra. The main components of semen in men are spermatozoa and seminal plasma. The spermatozoa of which are produced in the testes, will further mature in the male epididymis and finally complete their final change in the female vagina. Seminal plasma is mainly composed of various fluids, including prostate fluid, fluid secreted by the seminal vesicle glands, and urethral bulbourethral fluid. Among the components of semen are water, mucus, proteins, enzymes, calcium, and carbon dioxide. Semen is stored in the patient’s seminal vesicles bilaterally before it is expelled. When the patient reaches orgasm, the seminal vesicle fluid is expelled through the urethra via the vas deferens that opens into the urethra. To summarize, if there is any discomfort, consult a doctor promptly.
