The absence of spermatorrhea during puberty and the absence of other abnormalities are usually normal. If there are other symptoms such as abnormal development of reproductive organs, the possibility of pathological factors should be considered. The sex organs of adolescent males are gradually maturing, and they will produce sperm continuously and store them in the seminal vesicles. Once they are stored in excess, spermatozoa may occur when they are slightly stimulated. However, some adolescent males who masturbate regularly or have normal sex can ejaculate sperm regularly, and the phenomenon of no sperm loss may occur. It is important to note that adolescent males who persistently do not ejaculate, and who have abnormal penile and testicular development, or slow development of secondary sexual characteristics, should also consider the possibility of slow development and low hormone levels. Adolescent males who do not ejaculate for a long period of time can consult a doctor to confirm the diagnosis, and under the guidance of the doctor to be treated accordingly, do not carry too much psychological pressure.
