The seminal vesicles are a pair of sac-like glands that can be found within the male pelvis. They’re responsible for producing the majority of the components that make up精液。
Read on to learn more about the seminal vesicles.
The seminal vesicles are located below thebladderand above theprostate gland。An individual seminal vesicle consists of a single coiled tube off of which several pouches branch.
The tube of a seminal vesicle is made up of three different layers:
- 潮湿的专门细胞的内层，可产生精液囊泡液
- 平滑肌组织的中层
- 结缔组织的外层
一部分囊泡和vas deferenscombine to form the射精管, which eventually drains into the prostatic portion of the尿道。During ejaculation, the smooth muscle layer of the seminal vesicles contracts, releasing the seminal vesicle fluid into the ejaculatory duct.
The function of the seminal vesicles is to both produce and store fluid that will eventually become semen. This fluid comprises about
The fluid produced in the seminal vesicles provides an environment that’s very important for the proper functioning and survival of sperm. The main components of this fluid are:
- 果糖，一种为精子提供能量的糖
- 碱性液，有助于中和雄性尿道和雌性阴道的酸性性质
- Semenogelin等蛋白质，该蛋白质在精子周围形成类似凝胶的保护层
- phosphorus and potassium, which help sperm move
- prostaglandins, hormones that have a role in lowering the female immune response to semen
There are a variety of conditions that can affect the seminal vesicles, although they tend to be rare.
Seminal vesicle infection and abscess
A seminal vesicle abscess occurs when bacteria invade the seminal vesicles. This can occur after an infection of the urethra or the prostate gland. Treatment for an infection of the seminal vesicles is a course of antibiotics.
在某些情况下，可能会因感染而发生一个被称为脓肿的脓肿。在这种情况下，可能需要排干脓肿。
Seminal vesicle cysts
Cysts in the seminal vesicles are often asymptomatic, meaning they present no outward symptoms. They can be present from birth (congenital) or acquired. Acquired seminal vesicle cysts can arise from things like scarring from infection or a prior prostate surgery.
Depending on the size of the cyst, alaparoscopic可以执行外科手术以将其删除。
Seminal vesicle stones
The presence of stones in the seminal vesicles is very rare. They’re believed to form due to inflammation or structural abnormalities in the seminal vesicles. Reflux of urine back into the ejaculatory duct may also play a role in stone formation.
建议去除精确的囊泡结石，尤其是当它们大或有多个石头时。这可以通过endoscopicor laparoscopic surgical procedure.
Cancer of the seminal vesicle
在精液囊泡中发展的癌症非常罕见。截至2000年，
Many cancers that involve the seminal vesicles occur because of invasion of the seminal vesicles due to another malignant cancer, typicallyprostate cancer。The closeness of the seminal vesicles with the prostate makes this invasion possible.
精液囊泡状况的症状通常包括：
- abdominal, pelvic, or penile pain
- pain or discomfort when ejaculating
- 射精中的血液
- low volume of ejaculate
- 排尿痛苦
- blood in the urine
重要的是要注意，这些症状也可以指示其他骨盆，尿路或生殖疾病。如果您经历了精确囊泡状况的任何症状，则应与医生预约讨论。
由于精液中的大部分液体都在精液中贡献了大部分液体，因此保持健康很重要。请按照下面的提示进行良好的囊泡和生殖健康。
Practice safe sex
Be sure to practice safe sex with any new sexual partner. Condoms not only prevent unplanned pregnancies, but they can also防止性传播感染。感染会导致泌尿生殖道（包括精囊）的炎症和疤痕。
Try to maintain a healthy weight
锻炼并旨在保持健康的体重。更高的体重指数是associatedwith lower sperm movement and count.
Eat a healthy diet
您应该旨在食用富含蔬菜和水果的饮食，其中含有有益的抗氧化剂。包括全谷物和瘦肉。避免处理或饱和脂肪或糖分高的物品。
停止吸烟
Smoking cigarettes能够make your sperm less mobile and also lower your sperm count. Quitting smoking can be difficult but it’s possible. A doctor can help create aplan to quit smoking这适合您。
不要忽略令人担忧的症状
如果您注意到自己的症状与囊泡状况一致，请务必与医生预约以讨论您的担忧。
