The normal ejaculation volume for men is 2-6ml, if it is significantly more than this standard, it is recommended to go to the hospital for further examination to clarify the causes: 1. For patients who have been abstinent for a long time or have not had sex for a long time, it may cause an increase in the volume of semen during the first or first few times of sex, which is a normal phenomenon and not a disease condition. This is a normal phenomenon, not a disease. There is no ejaculation pain or discomfort in this case, and no related treatment is needed. 2. If there is vesiculitis, prostatitis or inflammation of the seminal caruncle, it can cause an increase in the secretion of the corresponding secretory organ, such as increased secretion of prostate fluid and increased secretion of seminal vesicle fluid, which can appear as an increase in semen volume. This is because prostatic fluid and seminal vesicle fluid are also a component of seminal fluid. However, both are accompanied by pain during ejaculation, or with yellowish semen, or with abnormal odor of semen, or with hematosperm and other symptoms, which need to be further confirmed by seminal vesicle prostate related examination. 3. If there is an abnormal increase in pituitary secretion of hormones, it can also manifest as an increase in ejaculation volume. This is a result of the fact that the ejaculation volume increases continuously, without any conscious symptoms, mostly related to factors such as precocious puberty or excessive secretion of gonadotropins.
