A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.
A cystic dilation of the EPIDIDYMIS, usually in the head portion (caput epididymis). The cyst fluid contains dead SPERMATOZOA and can be easily differentiated from TESTICULAR HYDROCELE and other testicular lesions.
Accumulation of serous fluid between the layers of membrane (tunica vaginalis) covering the TESTIS in the SCROTUM.
Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.
The network of channels formed at the termination of the straight SEMINIFEROUS TUBULES in the mediastinum testis. Rete testis channels drain into the efferent ductules that pass into the caput EPIDIDYMIS.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
A pouch or sac developed from a tubular or saccular organ, such as the GASTROINTESTINAL TRACT.
The convoluted cordlike structure attached to the posterior of the TESTIS. Epididymis consists of the head (caput), the body (corpus), and the tail (cauda). A network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of SPERMATOZOA.

Giant multilocular prostatic cystadenoma presenting with obstructive aspermia. (1/2)

Giant multilocular prostatic cystadenoma (GMPC) is a rare benign tumor involving the prostate gland. Microscopically, it masquerades phyllodes tumor or transitional zone hyperplasia. We report one case of GMPC arising from the prostate central zone (CZ), presenting with long-standing aspermia associated with seminal vesicle fibrous obliteration.  (+info)

Molecular analysis of aspermic Fasciola flukes from Korea on the basis of the nuclear ITS1 region and mitochondrial DNA markers and comparison with Japanese aspermic Fasciola flukes. (2/2)

It has been speculated that populations of aspermic Fasciola flukes in Korea and Japan have a close phylogenetic relationship. To evaluate this, we analyzed 33 Korean aspermic Fasciola flukes on the basis of nuclear ribosomal internal transcribed spacer 1 (ITS1) and mitochondrial NADH dehydrogenase subunit 1 (nad1) and cytochrome c oxidase 1 (cox1) sequences. Fh, Fg, and Fh/Fg types were detected in the ITS1 region and displayed the fragment patterns of F. hepatica, F. gigantica, and both species, respectively by a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Additionally, three concatenated haplotypes of nad1 and cox1(nad1/cox1) were detected, and 2 of these, Kor1/Kor1 (Fsp1/Fsp1) haplotype and Kor2a/Kor2 (Fsp2/Fsp2) haplotype, were shared by Korean and Japanese aspermic flukes. The Fst value (0.019), calculated using the concatenated sequences, indicated that Korean and Japanese aspermic Fasciola populations were genetically undifferentiated. Interestingly, a combination of the Fh/Fg type and Kor1/Kor1 haplotype was found at the highest frequency in Korean aspermic flukes, whereas the Fg type and Fsp2/Fsp2 haplotype combination was found at a conspicuously high frequency in Japanese aspermic flukes. This indicates that a founder effect caused by the introduction of infected hosts may have played a key role in the introduction of aspermic Fasciola flukes from Korea into Japan.  (+info)

Aspermia is a medical term that refers to the absence of semen, which is typically released during ejaculation in males. This condition can occur due to various reasons such as obstruction in the reproductive tract, retrograde ejaculation (where semen flows backward into the bladder instead of out through the urethra), or a failure of the testicles to produce sperm. Aspermia is often associated with infertility and requires medical evaluation and treatment.

A spermatocele is a type of cyst that develops in the epididymis, which is a small, coiled tube located on the back surface of the testicle. This cyst typically contains sperm and fluid from the epididymis, and it is usually benign and harmless.

Spermatoceles are often asymptomatic and may be discovered during a routine physical examination or self-examination. In some cases, however, they may cause discomfort or pain, particularly if they become large enough to press on the testicle or surrounding structures.

While spermatoceles do not typically require treatment unless they are causing symptoms, it is important to have them evaluated by a healthcare provider to rule out other potential causes of any symptoms and to ensure that appropriate treatment is provided if necessary.

A testicular hydrocele is a type of fluid-filled sac that forms around the testicle (testis), typically in the scrotum. This sac, known as the tunica vaginalis, normally contains a small amount of fluid that helps to lubricate and protect the testicle. However, when an excessive amount of fluid accumulates in this sac, it results in the formation of a hydrocele.

Testicular hydroceles can be congenital (present at birth) or acquired later in life due to various reasons such as injury, inflammation, or infection in the scrotal area. They are usually painless but may cause discomfort or a feeling of heaviness in the scrotum, especially when they become large. In some cases, hydroceles may resolve on their own without treatment, while others may require surgical intervention to drain the fluid and repair the underlying issue.

It is essential to differentiate between hydroceles and other conditions with similar symptoms, such as hernias or tumors, which may require more urgent medical attention. A healthcare professional can perform a physical examination and possibly recommend further testing, like an ultrasound, to confirm the diagnosis of a testicular hydrocele.

Epididymitis is defined as the inflammation of the epididymis, a curved tube-like structure located at the back of the testicle that stores and transports sperm. The inflammation can result from infection, trauma, or other causes, and may cause symptoms such as pain, swelling, and tenderness in the scrotum. In some cases, epididymitis may also be associated with urinary tract infections, sexually transmitted infections, or other medical conditions. Treatment typically involves antibiotics to treat any underlying infection, as well as pain relief measures and supportive care to help reduce symptoms and promote healing.

The rete testis is a network of tubules in the male reproductive system that serves as a passageway for sperm to travel from the seminiferous tubules, where sperm are produced, to the epididymis, where they mature. It is located in the mediastinum testis, which is the central part of the testicle.

The rete testis is made up of a series of interconnected tubules that are lined with simple cuboidal epithelial cells. These tubules merge to form larger ducts called efferent ductules, which then connect to the epididymis. The rete testis plays an important role in the transport and maturation of sperm, as well as in the regulation of fluid balance in the male reproductive system.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

A diverticulum is a small sac or pouch that forms as a result of a weakness in the wall of a hollow organ, such as the intestine. These sacs can become inflamed or infected, leading to conditions like diverticulitis. Diverticula are common in the large intestine, particularly in the colon, and are more likely to develop with age. They are usually asymptomatic but can cause symptoms such as abdominal pain, bloating, constipation, or diarrhea if they become inflamed or infected.

The epididymis is a tightly coiled tube located on the upper and posterior portion of the testicle that serves as the site for sperm maturation and storage. It is an essential component of the male reproductive system. The epididymis can be divided into three parts: the head (where newly produced sperm enter from the testicle), the body, and the tail (where mature sperm exit and are stored). Any abnormalities or inflammation in the epididymis may lead to discomfort, pain, or infertility.

Spermatoceles can be discovered as incidental scrotal masses found on physical examination by a physician or by self-inspection of the scrotum and testicles.[7] The various types of diagnosis for spermatocele types include hydrocele, varicocele, hernia, simple epididymal cyst, and neoplasm.[8] The primary care physician may diagnose and manage benign causes of scrotal masses such as hydrocele, varicocele and spermatocele. However, if a "must not miss" diagnosis related to testicular masses such as testicular torsion, epididymitis, acute orchitis, strangulated hernia and testicular cancer is suspected, the family physician must refer to a urologist.[19] Finding a painless, cystic mass at the head of the epididymis that is clearly separate from the testicle can indicate a spermatocele. Shining a light through the mass, a process known as transillumination, can also help differentiate between a fluid-filled cyst and a tumor, which would not allow as much light to pass.[20] If uncertainty exists, ...
