Epididymis
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.
Sperm Maturation
Testis
Spermatozoa
Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.

Testosterone
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
Androgens
Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.
Seminiferous Epithelium
The epithelium lining the seminiferous tubules composed of primary male germ cells (SPERMATOGONIA) and supporting SERTOLI CELLS. As SPERMATOGENESIS proceeds, the developing germ cells migrate toward the lumen. The adluminal compartment, the inner two thirds of the tubules, contains SPERMATOCYTES and the more advanced germ cells.
Orchitis
Inflammation of a TESTIS. It has many features of EPIDIDYMITIS, such as swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS and then the TESTIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.
Infertility, Male
Semen
Seminal Plasma Proteins
Proteins found in SEMEN. Major seminal plasma proteins are secretory proteins from the male sex accessory glands, such as the SEMINAL VESICLES and the PROSTATE. They include the seminal vesicle-specific antigen, an ejaculate clotting protein; and the PROSTATE-SPECIFIC ANTIGEN, a protease and an esterase.
Testosterone Propionate
Fertility
Sertoli Cells
Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.

Androgen-Binding Protein
Carrier proteins produced in the Sertoli cells of the testis, secreted into the seminiferous tubules, and transported via the efferent ducts to the epididymis. They participate in the transport of androgens. Androgen-binding protein has the same amino acid sequence as SEX HORMONE-BINDING GLOBULIN. They differ by their sites of synthesis and post-translational oligosaccharide modifications.

Cryptorchidism
A developmental defect in which a TESTIS or both TESTES failed to descend from high in the ABDOMEN to the bottom of the SCROTUM. Testicular descent is essential to normal SPERMATOGENESIS which requires temperature lower than the BODY TEMPERATURE. Cryptorchidism can be subclassified by the location of the maldescended testis.

Androstane-3,17-diol
Tissue Distribution
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
Spermatocele
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Leydig Cells
Nuclease Protection Assays
Techniques for measuring specific nucleic acid interaction with another nucleic acid or with a protein by digestion of the non-interacting nucleic acid by various nucleases. After all non-interacting regions are eliminated by nuclease digestion, the protected nucleic acid that remains is analyzed. DNA FOOTPRINTING utilizes this technique to analyze the DNA contact sites of DNA-BINDING PROTEINS.
Inhibition by amiloride of sodium-dependent fluid reabsorption in the rat isolated caudal epididymis. (1/2450)
The rate of fluid reabsorption was studied in the rat isolated caudal epididymal sac in vitro. 2 Part of the fluid reabsorption was found to be dependent on intraluminal Na+. Amiloride (0.1 mM) completely inhibited this component of fluid reabsorption. 3 The log dose-inhibition curve to amiloride was sigmoid and the IC50 value was found to be 1.6 muM. (+info)Morphology of the epididymal region and ductus deferens of the turkey (Meleagris gallopavo). (2/2450)
The ductal system of the reproductive tract of the male domestic turkey was studied by gross dissection and light microscopy of paraffin and Epon embedded tissues. The succession of ductules as one passes caudally from the testis was as follows: seminiferous tubules; rete testis; ductuli efferentes; connecting ductules; ductus epididymidis; ductus deferens; receptaculum ductus deferentis; papilla ductus deferentis. Non-ciliated cells of the male tract consisted of squamous and low cuboidal cells of the rete testis, granulated columnar cells lining the ductuli efferentes and connective ductules; agranulated columnar cells which formed the epithelium of the ductus epididymidis, ductus deferens, receptaculum and papilla ductus deferentis; and basal cells which were found in increasing number from the ductuli efferentes to the papilla. The basal cells had a reduced amount of cytoplasm and stained more intensely than the other cell types. Ciliated cells were apparent in the ductuli efferentes and connecting ductules, and these consistently stained lighter than the non-ciliated cells. Non-ciliated columnar cells of the ductuli efferentes and connecting ductules contained chromatophilic granules. Cytoplasmic blebbing into the ductal lumina was found associated with these non-ciliated cells as well as the agranular cells of the ductus epididymidis and deferens. Evidence obtained from this study suggests that the non-ciliated cells of the ductuli efferentes, ductus epididymidis and ductus deferens have a contribution to make to the seminal plasma by apocrine secretion. (+info)Glutathione-independent prostaglandin D2 synthase in ram and stallion epididymal fluids: origin and regulation. (3/2450)
Microsequencing after two-dimensional electrophoresis revealed a major protein, glutathione-independent prostaglandin D2 synthase (PGDS) in the anterior epididymal region fluid of the ram and stallion. In this epididymal region, PGDS was a polymorphic compound with a molecular mass around 30 kDa and a range of pI from 4 to 7. PGDS represented 15% and 8% of the total luminal proteins present in this region in the ram and stallion, respectively. The secretion of the protein as judged by in vitro biosynthesis, and the presence of its mRNA as studied by Northern blot analysis, were limited to the proximal caput epididymidis. Using a specific polyclonal antibody raised against a synthetic peptide, PGDS was found throughout the epididymis, decreasing in concentration toward the cauda region. PGDS was also detected in the testicular fluid and seminal plasma by Western blotting. Castration and efferent duct ligation in the ram led to a decrease in PGDS mRNA and secretion. PGDS mRNA was not detected in the stallion 1 mo after castration, and it was restored by testosterone supplementation. This study showed that PGDS is present in the environment of spermatozoa throughout the male genital tract. Its function in the maturation and/or protection of spermatozoa is unknown. (+info)Localization of sodium bicarbonate cotransporter (NBC) protein and messenger ribonucleic acid in rat epididymis. (4/2450)
An acidic environment is important for sperm maturation in the epididymis and also helps to maintain mature sperm in an immotile state during storage in this organ. Both an Na+/H+ exchanger and an H+ATPase have been implicated in this process. The H+ATPase is concentrated in specialized apical (and/or narrow) and clear cells of the epididymis, while the Na+/H+ exchanger has not yet been localized in situ. As in other proton-secreting epithelia, bicarbonate transport occurs in the epididymis, where it is implicated in luminal acidification. In this study we used an antibody raised against a fusion protein (maltose-binding protein: MBP-NBC-5) from the C-terminus of the recently cloned rat kidney Na+/HCO3- cotransporter (NBC) to localize this protein in the epididymis and vas deferens of the rat. The distribution of the respective mRNA was mapped by in situ hybridization. NBC message was strongly expressed in the initial segment and the intermediate zone of the epididymis, and the NBC-5 antibody gave a strong basolateral staining in both principal cells and apical/narrow cells in this region. Western blotting revealed a single band at about 160 kDa in the epididymis. The intensity of staining as well as mRNA levels decreased in the cauda epididymidis and in the vas deferens, where only weak staining was seen. Basolateral NBC may function in parallel with apical proton secretion to regulate luminal acidification and/or bicarbonate reabsorption in the excurrent duct system. (+info)Involvement of polyomavirus enhancer activator 3 in the regulation of expression of gamma-glutamyl transpeptidase messenger ribonucleic acid-IV in the rat epididymis. (5/2450)
Gamma-glutamyl transpeptidase (GGT) mRNA-IV and polyomavirus enhancer activator 3 (PEA3) mRNA are highly expressed in the initial segment of the rat epididymis, and both are regulated by testicular factors. PEA3 protein in rat initial segment nuclear extracts has been shown to bind to a PEA3/Ets binding motif, which is derived from the partially characterized GGT mRNA-IV promoter region. This suggests that PEA3 may be involved in regulating transcription from the rat GGT mRNA-IV gene promoter in the initial segment. Using DNA oligonucleotide primers and DNA sequencing analysis, an approximately 1500-basepair (bp) DNA sequence at the 5' region of the promoter was obtained. Using transient transfection, PEA3 activated transcription of the rat GGT mRNA-IV promoter only in cultured epididymal cells from the rat initial segment, but not in Cos-1 or NRK-52E cells. Promoter deletion analysis indicated that a PEA3/Ets binding motif between nucleotides -22 and -17 is the functional site for PEA3 to activate transcription of GGT promoter IV and that an adjacent Sp1 binding motif is also required to maintain promoter IV activity in epididymal cells. Transcriptional activation of promoter IV was shown to be epididymal cell-specific and PEA3-specific. In addition, PEA3 may act as a weak repressor for transcription of promoter IV, probably using a PEA3/Ets binding motif(s) distal to the transcription start site. A model of how PEA3 is involved in the regulation of transcription of GGT promoter IV in epididymal cells is proposed. (+info)An intact sperm nuclear matrix may be necessary for the mouse paternal genome to participate in embryonic development. (6/2450)
We have been interested in determining the minimally required elements in the sperm head that are necessary in order for the paternal genome to participate in embryogenesis. We used an ionic detergent, mixed alkyltrimethylammonium bromide (ATAB), plus dithiothreitol (DTT) to remove the acrosome and almost all of the perinuclear theca, leaving only the sperm nucleus morphologically intact. We also tested the stability of the sperm nuclear matrix by the ability to form nuclear halos. Sperm nuclei washed in freshly prepared 0.5% ATAB + 2 mM DTT completely decondensed when extracted with salt, but nuclei washed in the same buffer that was 1 wk old, and then extracted with salt, produced nuclear halos, indicating stable nuclear matrices. When we treated sperm heads with freshly prepared ATAB+DTT and injected them into oocytes, none of the oocytes developed into live offspring. In contrast, sperm heads treated in the same way but with 1-wk-old ATAB+DTT solution could support development of about 30% of the oocytes to live offspring. Electron microscopy demonstrated that most of the perinuclear theca had been removed in both cases. These data suggest that at least in the mouse, the only component of the spermatozoa that is crucial for participation in embryologic development is the sperm nucleus with a stable nuclear matrix. (+info)Identification of Rickettsia rickettsii in formalin-fixed, paraffin-embedded tissues by immunofluorescence. (7/2450)
With slight modification of a trypsin digestion technique, Rickettsia rickettsii were demonstrated specifically by immunofluorescence staining in Formalin-fixed, paraffin-embedded tissue sections from a human, rhesus monkey, and guinea pig with Rocky Mountain spotted fever and in infected membranes from a chicken embryo. Tissues were cut at 4 micron and, using geltain as a tissue adhesive, were hydrated in a routine manner. Sections were then digested in refrigerated 0.1% trypsin for 16 h, washed, and stained specifically for R. rickettsii by direct or indirect immunofluorescence. Rickettsial organisms were localized in affected vessels of the mammalian species and within the yolk sac epithelium of the chicken embryo. Specificity was confirmed by adsorbing antibody conjugates with R. rickettsii organisms. Trypsin digestion probably decreased tissue proteins which interfered with immunochemical attachment of antibody to the rickettsiae. The technique is valuable in that a diagnosis of Rocky Mountain spotted fever can be confirmed from Formalin-fixed tissues processed in a routine manner. (+info)Reversing adipocyte differentiation: implications for treatment of obesity. (8/2450)
Conventional treatment of obesity reduces fat in mature adipocytes but leaves them with lipogenic enzymes capable of rapid resynthesis of fat, a likely factor in treatment failure. Adenovirus-induced hyperleptinemia in normal rats results in rapid nonketotic fat loss that persists after hyperleptinemia disappears, whereas pair-fed controls regain their weight in 2 weeks. We report here that the hyperleptinemia depletes adipocyte fat while profoundly down-regulating lipogenic enzymes and their transcription factor, peroxisome proliferator-activated receptor (PPAR)gamma in epididymal fat; enzymes of fatty acid oxidation and their transcription factor, PPARalpha, normally low in adipocytes, are up-regulated, as are uncoupling proteins 1 and 2. This transformation of adipocytes from cells that store triglycerides to fatty acid-oxidizing cells is accompanied by loss of the adipocyte markers, adipocyte fatty acid-binding protein 2, tumor necrosis factor alpha, and leptin, and by the appearance of the preadipocyte marker Pref-1. These findings suggest a strategy for the treatment of obesity by alteration of the adipocyte phenotype. (+info) Epididymitis is an inflammation or swelling of the epididymis, a tube-like structure located at the back of the testicle that stores and carries sperm. It can be caused by infection or other factors, such as sexually transmitted infections (STIs), urinary tract infections (UTIs), or prostate problems. Symptoms may include scrotal pain, swelling, redness, and fever. Treatment depends on the underlying cause and may involve antibiotics, pain relief medication, or surgical intervention. Complications of epididymitis can include abscesses, infertility, and chronic pelvic pain.

Testicular diseases refer to any medical condition that affects the testicles, which are the oval-shaped organs located within the scrotum that produce sperm and testosterone. These diseases can cause a range of symptoms, including pain, swelling, and abnormalities in sexual function.
Some common types of testicular diseases include:
1. Testicular torsion: This is a condition where the spermatic cord becomes twisted, cutting off blood flow to the testicle. It is a medical emergency and can cause permanent damage if not treated promptly.
2. Epididymitis: This is an inflammation of the epididymis, a tube that runs along the back of the testicle and helps to store and transport sperm. It can be caused by bacterial infections or viral infections such as chlamydia or gonorrhea.
3. Orchitis: This is an inflammation of the testicles, usually caused by a virus or bacterial infection.
4. Hydrocele: This is a build-up of fluid around the testicle, which can be caused by infection, injury, or other factors.
5. Varicocele: This is a swelling of the veins in the scrotum, which can be caused by a blockage or weakness in the valves that control blood flow.
6. Testicular cancer: This is a type of cancer that affects the testicles, and it is relatively rare but can be aggressive if left untreated.
7. Undescended testicle(s): This is a condition where one or both testicles fail to descend from the abdomen into the scrotum during fetal development.
8. Testicular atrophy: This is a shrinkage of the testicles, which can be caused by a range of factors including aging, injury, or certain medical conditions.
9. Painful ejaculation: This is a condition where ejaculation causes pain in the testicles, and it can be caused by a range of factors such as inflammation or infection.
10. Low testosterone: This is a condition where the levels of testosterone in the body are lower than normal, which can cause a range of symptoms including low sex drive, fatigue, and osteoporosis.
It's important to note that some of these conditions can be caused by other factors as well, so it's always best to consult with a healthcare professional for an accurate diagnosis and treatment plan.
Orchitis is an inflammatory condition that affects one or both testicles, usually caused by a viral or bacterial infection. It can be a serious condition, especially if left untreated, and can cause complications such as testicular atrophy, infertility, and chronic pain.
Symptoms of orchitis may include:
* Scrotal pain
* Swelling of the scrotum
* Redness and tenderness of the scrotum
* Fever
* Chills
* Abdominal pain
* Nausea and vomiting
Treatment for orchitis typically involves antibiotics to clear up any bacterial infections, as well as supportive care such as rest, ice packs, and over-the-counter pain medication. In severe cases, hospitalization may be necessary to monitor and treat the condition.
Prevention of orchitis includes avoiding close contact with people who have the infection, practicing safe sex, and maintaining good hygiene. Vaccination against certain types of bacteria that can cause orchitis, such as the H. influenzae type b (Hib) vaccine, can also help prevent the condition.
It is important to seek medical attention if symptoms of orchitis are present, as early treatment can help prevent complications and improve outcomes.
Male infertility is defined as the inability of a man to conceive a child with his partner after one year of regular, unprotected sexual intercourse. It is estimated that approximately 10-15% of couples experience fertility issues, and in about 40% of these cases, the problem lies solely with the male partner.
Male infertility can be caused by a variety of factors, including:
1. Low sperm count or poor sperm quality: This is one of the most common causes of male infertility. Sperm count is typically considered low if less than 15 million sperm are present in a sample of semen. Additionally, sperm must be of good quality to fertilize an egg successfully.
2. Varicocele: This is a swelling of the veins in the scrotum that can affect sperm production and quality.
3. Erectile dysfunction: Difficulty achieving or maintaining an erection can make it difficult to conceive.
4. Premature ejaculation: This can make it difficult for the sperm to reach the egg during sexual intercourse.
5. Blockages or obstructions: Blockages in the reproductive tract, such as a blockage of the epididymis or vas deferens, can prevent sperm from leaving the body during ejaculation.
6. Retrograde ejaculation: This is a condition in which semen is released into the bladder instead of being expelled through the penis during ejaculation.
7. Hormonal imbalances: Imbalances in hormones such as testosterone and inhibin can affect sperm production and quality.
8. Medical conditions: Certain medical conditions, such as diabetes, hypogonadism, and hyperthyroidism, can affect fertility.
9. Lifestyle factors: Factors such as smoking, excessive alcohol consumption, and stress can all impact fertility.
10. Age: Male fertility declines with age, especially after the age of 40.
There are several treatment options for male infertility, including:
1. Medications to improve sperm count and quality
2. Surgery to repair blockages or obstructions in the reproductive tract
3. Artificial insemination (IUI) or in vitro fertilization (IVF) to increase the chances of conception
4. Donor sperm
5. Assisted reproductive technology (ART) such as ICSI (intracytoplasmic sperm injection)
6. Hormone therapy to improve fertility
7. Lifestyle changes such as quitting smoking and alcohol, losing weight, and reducing stress.
It's important to note that male infertility is a common condition and there are many treatment options available. If you're experiencing difficulty conceiving, it's important to speak with a healthcare provider to determine the cause of infertility and discuss potential treatment options.
A broad category of diseases and disorders that affect the male reproductive system and/or urinary tract. Examples include epididymitis, orchitis, prostatitis, and urethritis.
This definition of 'Genital Diseases, Male' is from the Healthcare Professionals Network (HPN) Thesaurus, a comprehensive collection of terms used in healthcare and related fields.
Cryptorchidism is a congenital abnormality that affects the development of the testes in male embryos. It is characterized by one or both testes failing to descend from the abdomen into the scrotum, resulting in the testes being located higher than normal within the groin area.
Cryptorchidism can be classified into two types:
1. Abdomenal cryptorchidism: In this type, the testis is located in the abdominal cavity above the inguinal ring and is not covered by any skin or membrane.
2. Inguinoscrotal cryptorchidism: In this type, the testis is located in the inguinal canal and may be covered by a thin layer of skin or membrane.
Cryptorchidism is usually diagnosed at birth or during childhood, and it can occur as an isolated condition or as part of other congenital anomalies. Treatment options for cryptorchidism include:
1. Watchful waiting: In mild cases, doctors may choose to monitor the child's development and delay any treatment until they are older.
2. Surgical repair: In more severe cases or those that cause discomfort or other complications, surgery may be recommended to move the testes into the scrotum.
3. Hormone therapy: In some cases, hormone therapy may be used to stimulate the descent of the testes.
4. Assisted reproductive technology (ART): In cases where fertility is a concern, ART such as in vitro fertilization (IVF) may be recommended.
It's important to note that cryptorchidism can increase the risk of complications such as testicular cancer, infertility, and twisting or inflammation of the testes (torsion). Regular check-ups with a healthcare provider are essential for monitoring and managing this condition.
A spermatocele is a benign cyst that forms in the epididymis, which is a tube-like structure located behind each testicle in the male reproductive system. It is caused by an accumulation of fluid and sperm within the epididymis, which can lead to swelling and distension of the tube.
Spermatoceles are usually small and do not cause any symptoms. However, if they become large enough, they can cause discomfort or pain in the scrotum or testicles. They may also affect fertility by blocking the flow of sperm from the epididymis into the vas deferens.
Spermatocele is a type of hydrocele, which means that it is caused by an accumulation of fluid within a closed sac-like structure. Hydroceles can occur in other parts of the body, such as the groin or abdomen, but spermatocele specifically affects the epididymis.
The exact cause of spermatocele is not known, but it may be related to inflammation or blockage of the epididymis. It can also occur as a result of surgery or trauma to the groin area.
Diagnosis of spermatocele is usually made through ultrasound or scrotal imaging. Treatment for spermatocele may involve draining the fluid from the cyst, or in some cases, surgical removal of the affected portion of the epididymis.
In conclusion, a spermatocele is a benign cyst that forms in the epididymis and can cause discomfort, pain, or fertility issues in men. It is important to seek medical attention if symptoms persist or worsen over time.
