The secretory proteins of the seminal vesicles are proteins and enzymes that are important in the rapid clotting of the ejaculate. The major clotting protein is seminal vesicle-specific antigen. Many of these seminal vesicle proteins are under androgen regulation, and are substrates for the prostatic enzymes, such as the PROSTATE-SPECIFIC ANTIGEN, a protease and an esterase.
The male reproductive organs. They are divided into the external organs (PENIS; SCROTUM;and URETHRA) and the internal organs (TESTIS; EPIDIDYMIS; VAS DEFERENS; SEMINAL VESICLES; EJACULATORY DUCTS; PROSTATE; and BULBOURETHRAL GLANDS).
Tumor or cancer of the MALE GENITALIA.
Membrane-bound compartments which contain transmitter molecules. Synaptic vesicles are concentrated at presynaptic terminals. They actively sequester transmitter molecules from the cytoplasm. In at least some synapses, transmitter release occurs by fusion of these vesicles with the presynaptic membrane, followed by exocytosis of their contents.
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
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.
A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.

Vesicles derived from the GOLGI APPARATUS containing material to be released at the cell surface.
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.
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.
The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.
Surgical removal or artificial destruction of gonads.
The measurement of an organ in volume, mass, or heaviness.
Complete or partial surgical removal of the prostate. Three primary approaches are commonly employed: suprapubic - removal through an incision above the pubis and through the urinary bladder; retropubic - as for suprapubic but without entering the urinary bladder; and transurethral (TRANSURETHRAL RESECTION OF PROSTATE).

Potent inhibition of CD4/TCR-mediated T cell apoptosis by a CD4-binding glycoprotein secreted from breast tumor and seminal vesicle cells. (1/751)

We previously isolated a CD4 ligand glycoprotein, gp17, from human seminal plasma; this glycoprotein is identical with gross cystic disease fluid protein-15 (GCDFP-15), a factor specifically secreted from primary and secondary breast tumors. The function of gp17/GCDFP-15 in physiological as well as in pathological conditions has remained elusive thus far. As a follow up to our previous findings that gp17 binds to CD4 with high affinity and interferes with both HIV-1 gp120 binding to CD4 and syncytium formation, we investigated whether gp17 could affect the T lymphocyte apoptosis induced by a separate ligation of CD4 and TCR. We show here that gp17/GCDFP-15 is in fact a strong and specific inhibitor of the T lymphocyte programmed cell death induced by CD4 cross-linking and subsequent TCR activation. The antiapoptotic effect observed in the presence of gp17 correlates with a moderate up-regulation of Bcl-2 expression in treated cells. The presence of gp17 also prevents the down-modulation of Bcl-2 expression in Bcl-2bright CD4+ T cells that is caused by the triggering of apoptosis. Our results suggest that gp17 may represent a new immunomodulatory CD4 binding factor playing a role in host defense against infections and tumors.  (+info)

The novel analgesic compound OT-7100 (5-n-butyl-7-(3,4,5-trimethoxybenzoylamino)pyrazolo[1,5-a]pyrimid ine) attenuates mechanical nociceptive responses in animal models of acute and peripheral neuropathic hyperalgesia. (2/751)

We investigated the effects of OT-7100, a novel analgesic compound (5-n-butyl-7-(3,4,5-trimethoxybenzoylamino)pyrazolo[1,5-a]pyrimidi ne), on prostaglandin E2 biosynthesis in vitro, acute hyperalgesia induced by yeast and substance P in rats and hyperalgesia in rats with a chronic constriction injury to the sciatic nerve (Bennett model), which is a model for peripheral neuropathic pain. OT-7100 did not inhibit prostaglandin E2 biosynthesis at 10(-8)-10(-4) M. Single oral doses of 3 and 10 mg/kg OT-7100 were effective on the hyperalgesia induced by yeast. Single oral doses of 0.1, 0.3, 1 and 3 mg/kg OT-7100 were effective on the hyperalgesia induced by substance P in which indomethacin had no effect. Repeated oral administration of OT-7100 (10 and 30 mg/kg) was effective in normalizing the mechanical nociceptive threshold in the injured paw without affecting the nociceptive threshold in the uninjured paw in the Bennett model. Indomethacin had no effect in this model. While amitriptyline (10 and 30 mg/kg) and clonazepam (3 and 10 mg/kg) significantly normalized the nociceptive threshold in the injured paw, they also increased the nociceptive threshold in the uninjured paw. These results suggest that OT-7100 is a new type of analgesic with the effect of normalizing the nociceptive threshold in peripheral neuropathic hyperalgesia.  (+info)

Testosterone control of nucleic acid content and proliferation of epithelium and stroma in rat seminal vesicles. (3/751)

Tissue wet weight, nucleic acid content and epithelial and stromal cell numbers were measured in the seminal vesicles of sexually mature male rats. After castration, tissue weight and RNA decreased rapidly and in aprallel to reach, after 14 days, values only 15-20% of those in control (not castrated) animals. During this period, DNA decreased to a much lesser extent (by about 40%), but this change in DNA correlates well with the observed loss of cells from the epithelium. Testosterone in vivo promoted an immediate resynthesis of RNA, the value characteristic of control animals being reached within 80h. Delays occurred in the hormone-induced regain of tissue weight (30h) and DNA (40h), each of which preceded proliferation of the epithelium (40--50h). The cells of the stroma were unaffected by these changes in the androgenic statls of the animal. It is suggested that these proliferative changes in the epithelium cannot account for the previously reported induction by testosterone of basic secretory proteins in this tissue.  (+info)

Seminal tract infections: impact on male fertility and treatment options. (4/751)

Bacterial and viral infections of the genital tract may be important aetiological factors for male infertility. Infectious processes may lead to deterioration of spermatogenesis, impairment of sperm function and/or obstruction of the seminal tract. Detection of bacteria in semen does not necessarily signify infection since bacteriospermia may represent contamination, colonization or infection. Reported prevalence of Ureaplasma urealyticum in human semen varies from 10 to 40%. Enterobacteria can even be found in up to 90% of semen samples depending on the sensitivity of detection methods used. Chlamydia trachomatis is the most frequent sexually transmitted bacterial organism in industrialized countries. It is suggested that its main influence is due to sexual transmission resulting in tubal disease and subsequent infertility in the female partner rather than a direct influence on male reproductive functions. The effect of leukocytospermia on male fertility is controversial. This is probably due to different detection methods, different populations studied and to the fact that leukocyte subtypes in semen may have different functions. In addition to potentially negative effects, leukocytes may even have protective effects on spermatozoa. Only recently have amplification methods been established to detect viruses in semen with high sensitivity and specificity. It is unclear if these infections significantly contribute to male infertility.  (+info)

Many LH peaks are needed to physiologically stimulate testosterone secretion: modulation by fasting and NPY. (5/751)

The pulsatile luteinizing hormone (LH) and testosterone secretions were studied during serial blood collections performed at 7-min time intervals in the male rat. In fed rats, a discontinuous pattern of LH secretion was observed. Periods without secretion alternated with active secretory episodes consisting in trains of three to four LH peaks that triggered testosterone secretion usually 1-2 h later. The magnitude of the testosterone response was not correlated with the amplitude of the LH peaks. Isolated, single peaks of LH did not evoke clear testosterone responses. Forty-eight hours after initiation of fasting, testosterone secretion was markedly decreased, but integrated LH secretion was only partly reduced. Chronic infusion of neuropeptide Y (NPY; 18 microgram/day, icv) reduced testosterone secretion to very low levels and abolished pulsatile LH secretion or testosterone response to isolated LH peaks. In conclusion, the stimulation of testosterone secretion by LH necessitates several LH peaks organized in a proper sequence, and the testosterone response is not immediate. Low testosterone secretion in fasting rats appears to result from disappearance of coordinated, multiple LH peaks of sufficient size. Inhibition of the gonadotropic axis achieved by central NPY administration is due to either absence of LH peak "clusters" or occurrence of nonfunctional single LH peaks.  (+info)

Comparison of the peroxidase reaction kinetics of prostaglandin H synthase-1 and -2. (6/751)

Prostaglandin H synthase isoforms 1 and 2 (PGHS-1 and -2) each have a peroxidase activity and also a cyclooxygenase activity that requires initiation by hydroperoxide. The hydroperoxide initiator requirement for PGHS-2 cyclooxygenase is about 10-fold lower than for PGHS-1 cyclooxygenase, and this difference may contribute to the distinct control of cellular prostanoid synthesis by the two isoforms. We compared the kinetics of the initial peroxidase steps in PGHS-1 and -2 to quantify mechanistic differences between the isoforms that might contribute to the difference in cyclooxygenase initiation efficiency. The kinetics of formation of Intermediate I (an Fe(IV) species with a porphyrin free radical) and Intermediate II (an Fe(IV) species with a tyrosyl free radical, thought to be the crucial oxidant in cyclooxygenase catalysis) were monitored at 4 degrees c by stopped flow spectrophotometry with several hydroperoxides as substrate. With 15-hydroperoxyeicosatetraenoic acid, the rate constant for Intermediate I formation (k1) was 2.3 x 10(7) M-1 s-1 for PGHS-1 and 2.5 x 10(7) M-1 s-1 for PGHS-2, indicating that the isoforms have similar initial reactivity with this lipid hydroperoxide. For PGHS-1, the rate of conversion of Intermediate I to Intermediate II (k2) became the limiting factor when the hydroperoxide level was increased, indicating a rate constant of 10(2)-10(3) s-1 for the generation of the active cyclooxygenase species. For PGHS-2, however, the transition between Intermediates I and II was not rate-limiting even at the highest hydroperoxide concentrations tested, indicating that the k2 value for PGHS-2 was much greater than that for PGHS-1. Computer modelling predicted that faster formation of the active cyclooxygenase species (Intermediate II) or increased stability of the active species increases the resistance of the cyclooxygenase to inhibition by the intracellular hydroperoxide scavenger, glutathione peroxidase. Kinetic differences between the PGHS isoforms in forming or stabilizing the active cyclooxygenase species can thus contribute to the difference in the regulation of their cellular activities.  (+info)

Significant changes in volume of seminal vesicles as determined by transrectal sonography in relation to age and benign prostatic hyperplasia. (7/751)

We evaluated the changes in volume of the seminal vesicles as determined by transrectal sonography in terms of the possible relationship with aging, lower urinary tract symptoms and benign prostatic hyperplasia (BPH) in community based populations in Japan. In 641 men (55-86 year, mean 67) on a mass screening program for prostatic diseases, the maximum horizontal area of the seminal vesicles (MHA) was compared with age, American Urological Association (AUA) symptom index scores and transrectal ultrasonic parameters of the prostate including prostatic volume, transition zone (TZ) volume, TZ index and presumed circle area ratio (PCAR). Simple regression analyses demonstrated that MHA correlated significantly with age, prostatic volume, TZ volume, TZ index and PCAR, but not with AUA symptom index scores. Multiple regression analysis revealed age, prostatic volume and PCAR to be independent determinants of MHA. There was a difference in MHA between subjects with BPH (7.1+/-2.5 cm2) and those with a normal prostate (5.6+/-2.1 cm2) with a statistical significance. In the morphological evaluation of the seminal vesicles, the significant influence of age and BPH has to be taken into account.  (+info)

Hyperplasia in multiple smooth muscle tissues in transgenic mice expressing a temperature-sensitive SV40 T-antigen under the control of smooth muscle alpha-actin regulatory sequences. (8/751)

Control of smooth muscle cell (SMC) proliferation is of fundamental importance in the development and pathology of the vasculature. To derive vascular SMC with conditional inactivation of negative cell cycle regulatory proteins in the context of smooth muscle protein expression, a 3.4 kb fragment of the mouse SMC alpha-actin promoter was used to target a temperature-sensitive mutant SV40 T antigen (tsA58) to smooth muscle in transgenic mice. Mice with this genotype display a heritable phenotype of abnormal SMC proliferation in the central tail artery, vasa deferentia, seminal vesicles, prostate, and uterus, with the latter resembling uterine leiomyomatosis and prostatic hypertrophy. Neither the aorta nor other viscera manifested abnormal proliferation. Cultures from aorta, vas deferens, seminal vesicle, and kidney tissue were characterized with regard to protein expression, stability, and matrix remodelling capacity. The alpha-actin content/cell was up to 3-4-fold higher, as well as more stable than in primary SMC cultures, suggesting successful selection for propagation of cells expressing this differentiation marker. All cells displayed enhanced growth at the permissive temperature. As an initial functional assessment, the cells were compared to non-transformed mouse aortic SMC with respect to the ability to remodel collagen gel matrices, and demonstrated conservation of this physiologic function. This in vivo analysis of the SMC alpha-actin promoter supports a broader range of smooth muscle-directed expression activity than previously recognized, and establishes the feasibility of its use to direct transgene expression to vascular as well as genito-urinary smooth muscle. The targeted expression of the tsA58 T antigen has yielded transgenic animals with several manifestations of smooth muscle hyperplasia; these animals have in turn permitted the derivation of several murine SMC lines with phenotypic stability and conditionally-modulated proliferation. These cells will allow expansion of derivative transfected smooth muscle cell lines under permissive conditions, as well as oncogene inactivation at the restrictive temperature when desired for functional studies.  (+info)

All the major androgen-regulated secretory proteins of rat seminal vesicles have been purified in high yield from polyacrylamide gels using electroelution. In the process a sixth previously undocumented protein has been identified. Amino acid compositions of all the proteins are very similar and highly unusual, being high in lysine and arginine, and with 40-50% of the residues accounted for by serine, glycine and glutamate/glutamine. N-Terminal amino acid sequences for 3 of the proteins show that they are clearly the products of related genes. At least one of the other proteins is N-terminally blocked in vivo. Antibodies specific for each protein have been raised and provide evidence of structural similarity between the proteins. The antibodies were also used in immunofluorescence histochemistry with the rat copulatory plug, showing for the first time that all the major proteins of seminal vesicle secretion are components of this reproductive structure.. ...

AU - Hamann, W.. PY - 1986/1/1. Y1 - 1986/1/1. N2 - Congenital seminal vesicle cysts represent a rare but illustrative type of embryological malformation. They often are combined with ipsilateral upper urinary tract abnormalities. In most of the cases described in the literature the diagnosis has been made with rather invasive procedures. On the basis of our experience with 3 cases we recommend pelvic ultrasonography as the initial study in patients in whom such a malformation is suspected. Although other radiological procedures may be required to confirm the diagnosis, this approach appears to be cost-effective and accurate in most instances. The treatment of such malformations should be restricted to symptomatic cases and usually consists of vesiculectomy with or without removal of the ipsilateral ...

LSN was easily identified and isolated grossly. Antegrade catheterization via the SV tail to the main lumen was performed similar to the technique of i.v. catheterization, and the pressure recording was quite satisfactory. The vesicle response to ES was frequency-dependent and reproducible. Under the conditions of 10 V and 1 ms, the maximal vesicle pressure was 81.7 ± 2.8 mmHg with 80 Hz of ES. The inhibitory response of SV to ES by clomipramine was concentration-dependent. Clomipramine (3 mg/kg) could inhibit 53% of control responses (n = 7). This ...

Question - Have grade -II prostatomegaly and small seminal vesicle cyst. Do I need urgent medical cure?. Ask a Doctor about Prostate, Ask a Urologist
After castration, treatment with 17 beta-estradiol (20 micrograms/kg.day) for 3 days induced the LF mRNA in the seminal vesicle of both control and prenatally DES-exposed mice; however, the levels in DES-treated tissues were approximately 6-fold higher than those in control tissue.. This report describes the presence of LF in seminal vesicle tissues and secretions of prenatally DES-exposed mice, as determined by immunohistochemistry and Western blot analysis.. Further, these data are correlated with immunolocalization of the estrogen receptor in the seminal vesicle tissue.. We conclude that the seminal vesicle of prenatally DES-exposed male mice has acquired two key characteristics of female tissues, namely LF production/regulation and estrogen receptor localization/distribution similar to that in uterine tissues.. ...
In this report we determined that the level of LTF mRNA is minimal in the seminal vesicles of normal mice.. In contrast, expression of LTF mRNA in the seminal vesicles of developmentally estrogenized males was both constitutive and estrogen inducible.. The mRNA for the major estrogen-inducible uterine secretory protein, lactoferrin (LF), was constitutively expressed in the seminal vesicle of male mice exposed prenatally to DES, but not in the seminal vesicle of control mice. The results suggested that this alteration may be an example of atypical gene expression after hormonal manipulation early in development.. ...
Ectopic prostatic tissue and seminal vesicle at pericolic fat is extremely rare. The nodules in the pericolic fat could raise a dilemma of metastatic deposits in cases of rectal adenocarcinoma. A 61 years old male underwent abdomino-perineal resection for rectal carcinoma. Nodules along with lymph nodes from pericolic fat were sampled to assess the spread. Histopathological and immunohistochemical staining of one nodule confirmed it to be the prostatic tissue while another nodule to be seminal vesicle. Seminal vesicle and prostatic heterotopia is significant in several respects, either symptomatic or asymptomatic, as the ectopic tissue can be endoscopically and histologically confused with malignancy of urinary or lower gastrointestinal system and may reflect divergent differentiation or a malformative process. ...

Adenocarcinoma is most common epithelial tumour, and the Clear Cell variant of Adenocarcinoma (CCA) so far has not been reported in literature. Primary SV malignancies like adenocarcinoma pose a diagnostic dilemma as it becomes difficult to differentiate it from secondaries or as involvement from other adjacent organs even with imaging, histopathology and Immunohistochemistry (IHC).

It is very significant that these two apertures should be so extremely small, much smaller than the two seminal ducts. Because the two seminal vesicles are only laterally attached to their ducts it may happen (in contradistinction to the urinary apparatus, in which both the ureters discharge into the bladder itself), that sperm cells simply pass by the seminal vesicle without entering it. In this manner it might only too easily happen that semen would escape with urine unnoticed, without exercising its fertilising function, as is sometimes the case in serious paralytic conditions (spermator-rhea seminal emission without erection). But the extreme fineness of the two apertures in itself causes a resistance as elastic as the best occlusory muscle. So the antagonism in connection with the secretion of semen is unmistakable, even for those sperm-cells which have not penetrated into the seminal vesicles.. The problem of the ejaculation of the semen is rendered very much more difficult, because on ...

Rats can be used as a model organism to teach physiological concepts in a laboratory setting. This article describes a two-part laboratory that introduces students to hypothesis testing, experimental design, the appropriate use of controls and surgical techniques. Students perform both a castration and sham-control surgery on male rats and test the effects of reduced testosterone due to castration on the weight and histology of seminal vesicles. After performing the surgeries and collecting the data, students learn histological techniques, as well as empirical data collection, analysis and interpretation. Demonstrating the effects of testosterone through castration surgery bridges concepts learned in a traditional physiology class setting with data gleaned from research in a laboratory. Overall, the male castration surgery provides students with hands-on skills and an understanding of the work done by scientific researchers and health care professionals.

Results: The mean age was 64 years (range: 50-76 years) with mean and median PSA of 17.98 ng/ml (range: 0.3-68.3 ng/ml) and 12.1 ng/ml, respectively. With increase in preoperative Gleason score, chance of organ confinement decreases (P=0.002) and capsular penetration increases (P=0.004) linearly. With increasing serum PSA, there is linear decrease in trend of organ-confined disease (P=0.03) and increased chances of seminal vesicle involvement (P=0.02). Patients with higher clinical stage have less probability of localized disease (P=0.007) and more chances of capsular penetration (P=0.04) and seminal vesicle involvement (P=0.004). Conclusion: Our data suggest that patients with higher preoperative serum PSA, Gleason score, and clinical stage have more chances of advanced pathological stage following RARP ...
Fred,. It is common to read from newly diagnosed folks about those psychological feelings occurring allover the body. We try connecting any little feel with the cancer because the day before diagnosis we were healthy and now we think we are rotten. In fact we are now listening to our body more attentive to the extent that even the work of hearts valves is noticed or thought to be felt. Our brain is tricking us and at such a status we become vulnerable to medical vultures. Pain may exist in very advanced cases of prostate cancer (PCa) when metastases have deteriorate bone or have interfere with the functioning of an organ but these are rare cases in young newely diagnosed patients with low PSA (,50).. Some doctors may be tempted to urge patients to decide quickly for avoiding spread, which is an erroneous way of thinking. PCa does not spread that fast and your status of today would not be much different if it were 4 to 6 months later. Apart from that the treatment process would be the same with ...

A: The seminal vesicles are not only warehouse store tags Ahoinat sperm after the arrival of the testis, but it is a very important source for the production of fruit sugar (fructose), which is an indispensable element to feed Ahoinat sperm. The percentage of the sugar concentration of 120-200 mg per cent of the semen, is this amount of sugar to give enough power for about one hundred million sperm Hoin for twenty hours. Therefore, if I said the proportion of fructose in the semen than normal (as sometimes occurs in inflammatory seminal vesicles) that lead to abnormal phenomena on the one hand Ahoinat sperm count, or the movement or shapes. This may be a cause of infertility. ...
To understand how reproductive hazards affect a mans ability to have healthy children, it is important to understand how the male reproductive system works.. The testicles have two important functions: (1) they produce the hormone testosterone, which produces the deep male voice, beard, and sex drive; and (2) they produce sperm.. After the sperm are made (in about 72 days), they are stored in the epididymis, the outer structure of the testicles. The sperm remain in the epididymis for about 15 to 25 days. While there, they mature and develop the ability to swim. If the sperm are not ejaculated, they eventually die and are absorbed by the body.. When a man ejaculates, the mature sperm cells move through the vas deferens (the tube cut in a vasectomy) and past the seminal vesicles and prostate gland. The seminal vesicles and the prostate provide most of the liquid in semen.. The semen is deposited in the vagina and the sperm must then swim through the cervix into the uterus and up into the ...
The motivation behind the organs of the male conceptive framework is to play out the accompanying capacities: To deliver, keep up, and transport sperm (the male regenerative cells) and defensive liquid (semen) To release sperm inside the fe...
I am sorry to hear about this new PSA test, even though it is much lower than the other two. And thank you for your kind words about my surgery. In may case, I had no ECE, seminal vesicle invasion, nodal involvement, or positive surgical margins, so I stand a good chance at cure, but as you can tell, nothing is certain when it comes to cancer (I was forced not to participate in the test for circulating tumor cells based on the chance of infection, since prior to surgery they use needle aspiration of the bone marrow for that test). Anyway, I just posted a reply on a case of biochemical recurrence. I mention CellSearchTM there. It would prove useful if your father had this test done, for at least it would lend some indication if he is in real trouble. Read what I posted there (I wrote about other ways to control the cancer, at least a little bit, for the time being). Although I have no answer for why the PSA is bouncing around like this (consistent with radiotherapy but not surgery), the good news ...

Provided the above examinations show normal findings, nothing further needs to be done.. Hematospermia usually resolves on its own over time.. In some men, it may be a recurrent problem and develop on an intermittent basis.. Rarely, it may be a steady ongoing problem. In these circumstances, a transrectal ultrasound may be done to evaluate the seminal vesicle and prostate. Prostate ultrasound is done by inserting a small probe into the rectum that takes sonographic pictures of the prostate and seminal vesicles. This is a simple office procedure that is similar to a digital rectal exam. Ultrasound is carried out to make sure there are not abnormalities such as cysts or calcifications in the seminal vesicle or prostate.. If there is a persistent hematospermia, then treatment with Proscar (finasteride) for several months may be recommended. Proscar is a drug that was designed to reduce the size of the prostate in men with BPH (benign prostatic hyperplasia), which is the normal enlargement of the ...

There is a high relapse rate for patients who have undergone prostatectomy and have pathologic extracapsular prostate extension, positive surgical margins or seminal vesicle involvement (pathologic stage 3 disease). While adjuvant radiation improves progression-free and overall survival, approximately half of these patients will develop recurrence. Similarly, radiation therapy has become the standard salvage therapy for patients with rising PSA ,0.1 - , 2.0 ng/mL. In common solid tumors such as NSCLC, head and neck cancer and upper gastrointestinal cancers, the addition of chemotherapy to radiation improves survival. It is hypothesized that the addition of radiosensitizing chemotherapy to standard adjuvant radiation will improve survival in patients with stage 3 prostate cancer after prostatectomy and patients with rising PSA , 2.0 ng.mL without detectable disease. Taxanes are powerful radiation enhancers since they synchronize tumor cells in G2/M the most radiosensitive phase of the cell ...

Hemospermia is divided in Primary and Secondary Hemospermia. In Primary Hemospermia, the patients only symptom is the presence of blood in the semen. Before setting the diagnosis, the physician has to make sure that there is neither any microscopic/macroscopic hematurea nor any asymptomatic urinary tract infection. Primary hemospermia is a self-limiting condition -in 15% of patients it occurs as an individual episode. In Secondary Hemospermia, the cause is usually known; for example, prostate biopsy, prostate cancer or urinary tract infection, particularly prostatitis. However, there are some other more rare causes, such as:. ...
Once a man is capable of having erections, he generally has four to five erections each night. You generally dont notice them because you are asleep, but they generally occur during the phase of sleep known as REM (rapid eye movement). This is the phase when you dream. Since you usually pass through the REM phase just before waking up, you usually find yourself with an erection. There is a secondary reason for this happening. When you are sexually aroused, muscles in your prostate gland close off the path to your bladder and open the path to the ejaculatory ducts. You have small muscles that hold the bladder closed until you are ready to pee, and the arousal brings in a second set of muscles to make sure urine doesnt escape while you sleep. It happens just before you wake up in the morning because your bladder is full and it is pressing against your seminal vesicles. Recall that as your seminal vesicles become full, you are more easily aroused. Well, in the morning the seminal vesicles may not ...

Thanks for your questions. Lots of people have questions about sperm and semen, and how they are made.. Sperm is the male gamete or sex cell. Sperm contain the genetic information of sex-assigned at birth males.. Semen is fluid that contains both sperm and seminal fluid (a whitish fluid). Seminal fluid is made by the seminal vesicles and prostate gland.. Testicles have very small tubes called seminiferous tubules; this is where sperm develop. As sperm cells mature and develop, they move through the epididymis (a coiled tube). Sperm cells finish development in the epididymis. They are also stored in the epididymis until ejaculation, when they move to the vas deferens (or sperm duct).. The vas deferens and seminal vesicle come together at the ejaculatory duct. This is where sperm and seminal fluid meet to form semen. The ejaculatory duct then empties into the urethra (urine tube). The urethra ends at the tip of the penis ...

Urology is the specialty of medicine that focuses on the urinary tracts of males and females, and on the reproductive system of males. Medical professionals specializing in the field of urology are called urologists and are trained to diagnose, treat, and manage patients with urological disorders. The organs covered by urology include the kidneys, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate and penis). In men, the urinary system overlaps with the reproductive system, and in women the urinary tract opens into the vulva. In both sexes, the urinary and reproductive tracts are close together, and disorders of one often affect the other. Urology combines management of medical (i.e., non-surgical) problems such as urinary infections, and surgical problems such as the correction of congenital abnormalities and the surgical management of cancers. Such abnormalities within the genital region are called genitourinary ...

Each drop of semen represents a concentrate of lecithin, hormones, minerals and vitamins equal to 60 drops of blood. Hence, the loss of this fluid drains the blood of its best elements. Seminal fluid is potential nerve and brain nutriment and when not wasted of lost through involuntary emission, it is absorbed by lymphatics which line the seminal vesicles and carried to the recepaculum chyli, from where it ascends via the thoracic duct to the left subclavian vein prior to its entrance to the heart, and in this way lymphatically resorbed seminal fluuid enters the circulation. The conserved lecithin is then carried by the blood to nerve and brain cells, which require it for their nourishment and vital activity. FOr this reason, sexual losses, voluntarily or involunarily, rob the nerves and brain of nourishment; and, if they are excessive, lead to nervous and mental diseases. Since ancient times, it was known to physicians that the gonads or sex glands manufacture a vital substance which, if ...
Mr. Meiosis and Mrs. Meiosis gave birth to a sperm born on February 20, 2000 in Testi Hospital. The Meiosis family decided to name the sperm Sammy. When Sammy the sperm was 5 months old, Sammy became lost and ended up in the Epididymis. Sammy learned and matured over this period of time. Sammy started his journey to find the golden egg. Before Sammy left, his dad told him to always go left. Sammy did not know what he was talking about. He swam down to the Van Deferens Water Highway, he then reached Lake Bladder. There was a race to get to the other side of the lake, the winner would be able to find the golden egg and free dinner. Sammy won the race and ate at the Seminal Vesicle Diner.

5α-reductases, also known as 3-oxo-5α-steroid 4-dehydrogenases, are enzymes involved in steroid metabolism. They participate in 3 metabolic pathways: bile acid biosynthesis, androgen and estrogen metabolism. There are three isoenzymes of 5α-reductase, which vary in different tissues with age. 5α-Reductases catalyze the following chemical reaction: a 3-oxo-5α-steroid + acceptor ⇌ a 3-oxo-Δ4-steroid + reduced acceptor Thus, the two substrates of these enzymes are a 3-oxo-5α-steroid and acceptor, whereas its two products are 3-oxo-Δ4-steroid and a reduced acceptor. The enzyme is produced in many tissues in both males and females, in the reproductive tract, testes and ovaries, skin, seminal vesicles, prostate, epididymis and many organs, including the Nervous System. There are three isoenzymes of 5α-reductase: steroid 5α-reductase 1, 2, and 3 (SRD5A1, SRD5A2 and SRD5A3). 5α-Reductases act on 3-oxo (3-keto), Δ4,5 C19/C21 steroids as its substrates. 3-keto refers to the double bond of ...

I had no real symptoms before I was diagnosed with prostate cancer; Id had a bit of a slow urine flow, but I had thought that was just something that happens as you get older. It came as a shock when I was asked to make an appointment, as my PSA levels had come back very high. I was checked for urinary tract infections, had an MRI and bone scan, and then a prostate biopsy. While resting after my prostate biopsy, I was given antibiotics intravenously.. A week later, I was told I had an advanced and aggressive prostate cancer- much worse than I had expected. My cancer had also spread to the nearby seminal vesicles. The first treatment I was given was hormone therapy- this started as daily tablets, and after about a month I had a Zoladex implant* in my abdomen. Ill have three years of hormone treatment in all.. In November I had another DRE and was told that I had a 50/50 chance of recovery. I began radiotherapy treatment in January 2016, every day for 7 and a half weeks. I had to have a CT scan ...

Partially digested food starts to arrive in the small intestine as semi-liquid chyme, one hour after it is eaten.[citation needed] The stomach is half empty after an average of 1.2 hours.[31] After four or five hours the stomach has emptied.[32] In the small intestine, the pH becomes crucial; it needs to be finely balanced in order to activate digestive enzymes. The chyme is very acidic, with a low pH, having been released from the stomach and needs to be made much more alkaline. This is achieved in the duodenum by the addition of bile from the gall bladder combined with the bicarbonate secretions from the pancreatic duct and also from secretions of bicarbonate-rich mucus from duodenal glands known as Brunner's glands. The chyme arrives in the intestines having been released from the stomach through the opening of the pyloric sphincter. The resulting alkaline fluid mix neutralises the gastric acid which would damage the lining of the intestine. The mucus component lubricates the walls of the ...

... l agenesis[17] is a rare birth defect in which the trachea fails to develop. The defect is usually fatal though sometimes surgical intervention has been successful. A tracheoesophageal fistula is a congenital defect in which the trachea and esophagus are abnormally connected (a fistula). This is because of abnormalities in the separation between the trachea and oesophagus during development.[4] This occurs in approximately 1 in 3000 births, and the most common abnormalities is a separation of the upper and lower ends of the oesophagus, with the upper end finishing in a closed pouch.[4] Other abnormalities may be associated with this, including cardiac abnormalities, or VACTERL syndrome.[4] Such fistulas may be detected before a baby is born because of excess amniotic fluid; after birth, they are often associated with pneumonitis and pneumonia because of aspiration of food contents.[4] Congenital fistulas are often treated by surgical repair.[10] In adults, fistulas may occur because of ...
In tetrapods, the pharynx is much shorter, and the esophagus correspondingly longer, than in fish. In the majority of vertebrates, the esophagus is simply a connecting tube, but in some birds, which regurgitate components to feed their young, it is extended towards the lower end to form a crop for storing food before it enters the true stomach.[36][37] In ruminants, animals with four stomachs, a groove called the sulcus reticuli is often found in the esophagus, allowing milk to drain directly into the hind stomach, the abomasum.[38] In the horse the esophagus is about 1.2 to 1.5 m (4 to 5 ft) in length, and carries food to the stomach. A muscular ring, called the cardiac sphincter, connects the stomach to the esophagus. This sphincter is very well developed in horses. This and the oblique angle at which the esophagus connects to the stomach explains why horses cannot vomit.[39] The esophagus is also the area of the digestive tract where horses may suffer from choke. The esophagus of snakes is ...

The gustatory cortex is the primary receptive area for taste. The word taste is used in a technical sense to refer specifically to sensations coming from taste buds on the tongue. The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami. In contrast, the term flavor refers to the experience generated through integration of taste with smell and tactile information. The gustatory cortex consists of two primary structures: the anterior insula, located on the insular lobe, and the frontal operculum, located on the frontal lobe. Similarly to the olfactory cortex, the gustatory pathway operates through both peripheral and central mechanisms.[clarification needed] Peripheral taste receptors, located on the tongue, soft palate, pharynx, and esophagus, transmit the received signal to primary sensory axons, where the signal is projected to the nucleus of the solitary tract in the medulla, or the gustatory nucleus of ...
Because the beta cells in the pancreatic islets are selectively destroyed by an autoimmune process in type 1 diabetes, clinicians and researchers are actively pursuing islet transplantation as a means of restoring physiological beta cell function, which would offer an alternative to a complete pancreas transplant or artificial pancreas.[14][15] Islet transplantation emerged as a viable option for the treatment of insulin requiring diabetes in the early 1970s with steady progress over the last three decades.[16] Recent clinical trials have shown that insulin independence and improved metabolic control can be reproducibly obtained after transplantation of cadaveric donor islets into patients with unstable type 1 diabetes.[15] Islet transplantation for type 1 diabetes currently requires potent immunosuppression to prevent host rejection of donor islets.[17] An alternative source of beta cells, such insulin-producing cells derived from adult stem cells or progenitor cells would contribute to ...

The pituitary gland is found in all vertebrates, but its structure varies among different groups. The division of the pituitary described above is typical of mammals, and is also true, to varying degrees, of all tetrapods. However, only in mammals does the posterior pituitary have a compact shape. In lungfish, it is a relatively flat sheet of tissue lying above the anterior pituitary, but in amphibians, reptiles, and birds, it becomes increasingly well developed. The intermediate lobe is, in general, not well developed in any species and is entirely absent in birds.[21] The structure of the pituitary in fish, apart from the lungfish, is generally different from that in other animals. In general, the intermediate lobe tends to be well developed, and may equal the remainder of the anterior pituitary in size. The posterior lobe typically forms a sheet of tissue at the base of the pituitary stalk, and in most cases sends irregular finger-like projection into the tissue of the anterior pituitary, ...
