Patient's question:
Patient gender, male.:Please help me answer my question, dear doctors: I have recently noticed that my semen is becoming less, is there a problem?
Patient age, 19:
Doctor's answer:
There are three possible reasons for a low semen volume:(1) Poor function of the seminal vesicles and prostate: We know that semen consists of two parts—only a small portion is sperm, while the majority is seminal plasma. Seminal plasma is composed of secretions from accessory glands such as the seminal vesicles and prostate. If the seminal vesicles or prostate are underdeveloped, inflamed, or lack androgens, leading to reduced secretion function, the volume of semen will decrease.
(2) Obstruction or stenosis of the ejaculatory ducts: Sperm and seminal fluid from the seminal vesicles must enter the urethra for expulsion, and the exit is the ejaculatory duct. Specifically, the ampulla of the vas deferens merges with the seminal vesicle duct to form the ejaculatory duct. If the ejaculatory duct is blocked or narrowed, the seminal fluid and sperm cannot be expelled or are expelled in reduced amounts. As a result, only a small amount of fluid from the prostate duct, which opens directly into the urethra, is released during ejaculation, causing a significant decrease in semen volume.
(3) Diverticula or stenosis in the urethra: Diverticula or stenosis in the urethra can cause some of the semen to be retained in the diverticula or blocked above the stenotic area, preventing complete expulsion. It is recommended to seek professional medical evaluation for a detailed examination and targeted treatment.
