The seminal vesicle plays a crucial role in the male reproductive system. It is a pair of glands located behind the bladder and above the prostate. The primary function of these glands is to produce a significant portion of the seminal fluid, which constitutes a major part of semen. This fluid is rich in various substances that nourish and help transport sperm.

Structure and Location

The seminal vesicles are tubular structures that are situated posterior to the bladder. They are connected to the vas deferens and their secretions merge with sperm to form semen. Their placement allows them to effectively contribute to the ejaculate.

Function and Fluid Production

These glands secrete a thick, yellowish fluid that contains fructose, proteins, and enzymes. This fluid provides energy to the sperm and helps in their motility. It also contains substances that aid in the coagulation and liquefaction of semen, ensuring effective sperm delivery.

Clinical Significance

Disorders of the seminal vesicles, such as inflammation or cysts, can impact fertility. Conditions like seminal vesiculitis may affect the quality and quantity of seminal fluid, leading to potential complications in reproductive health.

In summary, the seminal vesicles are vital for male fertility, contributing essential fluids to semen that support sperm health and mobility. Understanding their function helps in diagnosing and treating reproductive issues.
