Causes of male infertility

Causes of male infertility
Back sterility man often either disorder in sperm count (few in number or absence) or the weakness of movement or to the large Chohadtha or weak ability to fertilization (although in numbers and strength of the movement), also cause infertility reasons for not entering the semen to the wife as the weak erection, or for other reasons unknown in rare occasions.
Attributed the small number of sperm or the lack of it either to double production in the testis or sperm duct obstruction leading to the outside.
* Embolism:Cause a blockage spermatic duct, which leads to sperm abroad in infertility.
If there is a blockage in the spermatic duct, withhold sperm inside the channel or within the testis (depending on position of the blockage), which leads to the absence or lack of numbers in the semen. We note that the blockage does not prevent the liquid from the exit, but only prevents sperm, where the fluid out of the seminal vesicle, prostate, and not from the testicle.
Embolism occurs and infertility as a result of infections, surgical errors or defects.
* Seminal tract infections result:
Enemy nationalityUrinary infection (due to reflux Paul microbes into the spermatic duct)Enemy general (as a result of the transmission of the microbe of infection elsewhere in the body to channel the sperm through the blood or other)Schistosomiasis.Tuberculosis.Obstruction and infertility occurs in these cases as a result of the accumulation of pus and fibrous tissue (caused by inflammation) in Hungarian and around it, which leads to Ansdadeh, in addition to a narrow channel by muscle contraction of the membrane in the wall under the influence of microbes that irritate the wall.

Surgical errors:
Are some surgeries in the inguinal region (the sperm into the passage channel and the lower abdomen on the right or left hand), and surgery of varicose veins and inguinal hernia. Also conducts other surgeries in the scrotum while also passing spermatic duct. If you made this surgery, however, is concerned, can be infected sperm channel بالانسداد result of exposure to injury, leading to infertility. And highlights this problem in particular in the process of inguinal hernia repair in children, which gets 27% of them obstruction leads to infertility.

Birth defects:
Sometimes that does not create spermatic duct from the ground up. And in this case related to testicular body by Oeitha vessels and be full of activity, but the sperm do not go out to the semen and the absence of the vas deferens (spermatic duct). This can happen up in both testicles or in one.
Can be accompanied by not creating the channel not to create sperm seminal vesicle, a gland that secretes seminal fluid, which leads to decrease the amount of fluid (in addition to being free of sperm). Can also be accompanied by this disappearance or atrophy in one of the kidneys.

And birth defects leading to infertility, a vesicle overgrown at the meeting point of the two channels Alntin channels bombers urethra into the prostate gland. This vesicle press channels bombers, leading to partial or total blockage of sperm in the channel, in turn leads to the disappearance of sperm and lack the amount of semen.

* Testicular damage (laziness production)
Varicose veins
Varicose disease of testicular veins (vein is a blood vessel which discharge waste-laden blood). This disease leads to widening the veins and blood stasis, loaded with waste and waste that are harmful to the testicle. Of this waste carbon dioxide, heat, and others. And in the upper grades of varicose veins, blood Ertdja in reverse direction from top to bottom, blaming hormone adrenaline clutch of the arteries, which leads to decreased blood flow loaded with oxygen and food to the testicle. That is how varicose lead to infertility.
In the case of testicular varicose, testicular damage irritation begins, and produce a number of sperm is much higher than usual, and then begins the sperm count and movement to fall to below the normal level, and distortions abound and less than the size of the testis and less hardness, the end of testicular atrophy (full damage). And it is not necessary to have this is accompanied by pain or certain symptoms, but can be detrimental to varicose veins clandestine Bal_khasip.
Consists of varicose veins on the left side often, and sometimes on both the left and right, and are rarely varicocele on the right side only. Increased incidence of varicocele on the left side due to several reasons, including the fact that vein left my head, making its content of blood rising to the top of heavier and slower movement by gravity if the person standing. Slow moving blood accumulates and helps breadth varicose vein and be.
Reasons to be varicocele whatever terms: the cause is unknown, but there are different theories about the cause, including the genetic factor leading to weak blood vessel walls, consisting of collagen. And imbalance in this article. Double wall leads to expansion of the vein due to its content of blood. Excludes from the varicose veins that occur on the right side without left, and are often the result of the body of the compressor in the abdomen, pressed the veins and prevent the rise of blood.
Symptoms of varicocele: varicose veins are often no symptoms, and discovered the damage and affected testicle, and the complaint in this case is infertility. In some cases large varicose veins, the patient complains of pain in the testicle, and in particular with the ongoing stand and walk for long distances. However, the occurrence of pain is the exception, not the rule. And here lies the importance of pre-marital testing, which reveal the presence of the disease so that was without symptoms.
Cryptorchid
Arise testis of the fetus inside the abdomen, and then gradually fall to settle in the bag at birth. If testicular refuses to go down and concerned within the abdominal cavity or the abdominal wall (undescended testicle), are susceptible to damage, tumors and infertility.
The corruption occurs, infertility and malignant tumors are a result of exposure testicular high temperature inside the abdomen, or the pressure and injuries if they are in the abdominal wall. Since the temperature inside the abdomen much higher than in the scrotum.
Cause testicular attached either a defect in the genes (genetic material), or endocrine disruption, or an obstacle to the road such as inguinal hernia. In rare instances, it can not create the testis of the foundation.
Diagnosis: locate testicular radiation television. If he does not appear testicular resort to MRI or CAT scan, did not show up, it does not mean they do not exist, because the aforementioned means is not accurate in the diagnosis. Faisal in this matter is to search for surgical abdominal lens, and is the most accurate and the best routes. And is a procedure does not take more than 30 minutes, through a hole in the border ten millimeters, and no need to stay overnight in the hospital, and can be made with this diagnostic procedure, the treatment of undescended testicle landed at the same time.
Be necessary to accelerate in the treatment of undescended testicle very seriously in order to avoid damage or incidence of malignant tumors.
In some cases, the testes no longer exist at all, any not Tkhalqa. And the distinction between this case and the case of undescended testicle possible test hCG stimulation test, where the man is injected hormone leads to activating the testicle - if any - to the secretion of the hormone testosterone. The increased level of the hormone, means that the presence of the testicles. And that has not increased, we conclude that the testicles did Tkhalqa.
And at other times, testicular be in its natural place, but it is up and down vigorously, sometimes Vtassad to the abdominal wall Vchabh undescended testicle, then do not soon return to its normal position. Ascension be the result of muscle contraction surrounding Bal_khasip, testicular and respond to constriction and escalate if they are small or lightweight. This case is called: testicular animation.
Segregation patient be sitting briefly in a squatting position for several minutes, during which landing testis to its natural place, if not outstanding.
Testicular animation is prone to tumors, but they are susceptible to injury when their ascent in the abdominal wall with seating and link belt and direct injury to the abdomen. Different doctors in the feasibility of surgery in this case, some فيراها necessary for cosmetic purposes and to protect them from infection, while others deem unnecessary because testicular susceptible even in its natural place. If you have been diagnosed with testicular moving at a young age, can wait several years until testicular growth and increase its weight Vtstqr in its natural place and do not respond to the surrounding muscle contraction. But if continued unchanged until puberty, there is no prospect of stability and must either be installed surgically Oalqpol intact with careful not exposed to injury. The use of hormones to increase testicular size and weight, it is a last resort.
As for the treatment of undescended testicle is surgical attempt Bailout, and laparoscopic If the testicle in the abdominal cavity or surgical conquest if they are in the abdominal wall. Landing attempt may succeed and may fail. If it fails, must eradicate undescended testicle because the left inside the abdomen leads to the occurrence of malignant tumors and will not help in procreation because testicular damage with its presence in the abdomen. Testicular eradication does not lead to impotence except in the case of the eradication of both. Here, have treatment at a dose of testosterone every three weeks for life to maintain sexual potency. Inguinal hernia repair should, if any.
Testicular landing at a young age is very important because the probability of maintaining reproductive capacity in this case, higher than if was testicular landing in old age.Treatment of undescended testicle using hormones to increase the weight of the testicle is contained in the opinion of most doctors only if testes close to the scrotum (the bag) and not in the upper abdomen, and if the disease is detected at a young age.
Birth defects
There are a lot congenital diseases coupled with damage (atrophy) of the testicles and infertility. Notably disease "Klinefelter" Klinefilter Syndrome, which causes the increase in the number of chromosomes (genetic material found in the nucleus of every cell) Pkromuzum one in this atrophy. Known that the number of units of the genetic material (chromosomes) in every cell of the man 46 chromosome. Increased to 47 lead to infertility, where there is no sperm production in full (in most cases)
And birth defects also affects the pituitary gland, which leads to a lack of anabolic hormones of the testis and thus to infertility. And the pituitary gland is the maestro who controls all the glands in the body through stimulating hormones secreted by the pituitary gland, every gland in its stimulating hormone. Of these diseases disease "Kalman" Kallman which prevents stimulating hormone secretion of the pituitary gland of the brain, and thus lack the secretion of anabolic hormones without glands, including the testicles.

Lack of hormones
Produced by the pituitary gland in the brain hormones governing the work of most other glands in the body, and testis. Refrain pituitary for secretion of hormones activated to produce sperm and notably hormone FSH result of injuries to the head or tumors in the brain or birth defects (as mentioned earlier) most notably disease "Kalman" Kallman Syndrom, which prevents secretion stimulating hormone of the pituitary gland of the brain, and thus lack of secretion of anabolic hormones without glands, including the testicles.

Infections
Some infections lead to testicular atrophy, infertility, and most notably the disease, "Abu Allkim" Mumps Orchitis and is the result of a virus that affects mostly children and lead to inflammation of the salivary gland (in the jaw), and accompanied by inflammation of the testicles (in 30% of cases).
Radiation
Exposure to radiation, either casual or consistently as in the treatment of tumors and in some professions (such as radiology technician and atomic energy workers) to testicular atrophy and infertility. The extent of damage to the testicles depends on the radiation dose and duration of exposure.Necessary before radiation exposure that are stored some sperm cryo special equipment, so used to impregnate the wife to later childbearing order, and because testicular be subject to full damage. It also recommends using gray insulation, which reduces the proportion of radiation that reaches the testes.
Chemicals
Affected testicle some chemicals, and on her head chemotherapy for tumors, and petroleum products, and toxic emissions, and lead, and others. Oncology patients are advised to store sperm before treatment Therapeutics chemical, and advised workers exposed to harmful chemicals to conduct periodic tests to take any medicine and refrain from exposure to toxic substance if there was a reduction in the activity of the testis.

Heat
High temperatures negatively affect the activity of the testis. For example, exposed workers in the fields of iron and steel furnaces and heavy transport to heat harmful Bal_khasip, and they revealed periodically to follow the reproductive capacity and saved if began to decline.
Injuries
Cause direct injury of the testis to laceration wall and out of their contents and bleeding. In case of injury should consult a specialist immediately testicle for TV and radiation detection, to determine the extent of damage and the need for immediate surgical intervention, and in order to preserve the remaining healthy tissue. And in severe cases can store some of the sperm emerging from infected testicular cooling (when the incision). Surgical repair is to stop the bleeding and sew the hole in the testis and empty assembly bloody.
Testicular torsion
Related testicular body's blood vessels carrying blood to oxygen-laden and other necessities of life (arteries) and another flying about waste and waste (veins).
If turned on its axis upper testicle Torsion, Taatdfr blood vessels around itself so that it closes completely. This results in the death of testis (atrophy) and consequent infertility.
Testicular torsion occurs without warning, and just be symptoms sudden pain. This pain can occur as a result of other things is torsion, such as orchitis (Epididymoorhitis), except that it is imperative to make sure there is no twisting, and treatment, if any, and the seriousness of the complications (testicular atrophy).
Should Escarh doctor specialist immediately when a pain Bal_khasip, and because delays in treatment lead to a loss of testicular fully .. Click here to see how to diagnose and treat

Tumors
Lead some tumors of the testicles to the erosion of tissue product of sperm, as well as the spread of tumor in various parts of the body. And lead others to the emergence of symptoms of femininity from breast enlargement and sexual weakness and futility.
Diagnosis is clinical detection and X-television and oncology indications, and are materials that are measured in the blood, indicate the presence of tumor and normal.


According to the type of tumor, the treatment that ranges from surgical excision and radiation therapy or chemotherapy, and all testicular hurt, necessitating storing sperm cryo before treatment begins.

Twice the efficiency of sperm
We have mentioned that the sperm to move towards the egg to meet them, and then he has to dissolve its outer wall with certain chemicals, then he has to rush into it. Weaken these properties in some diseases leading to infertility either as a result of the non-arrival of the sperm to the egg, or his access to them but the inability to penetrate due to lack of rapid movement tides. Add to that the possibility of lack of enzymes dissolving the wall of the egg in the vesicle Alokrozumih, which prevents penetration. These properties are affected in some diseases such as varicocele, infections and birth defects.
Antibodies
Are antibodies secreted by the immune system of the body to attack microbes and cancer cells, you paralyze the movement or to kill her. In some cases, targeting the immune system of the sperm and secreted antibodies him, which prevents it from movement and fertilization, and lead to infertility. This targeting occurs because of injuries, infections or sperm duct obstruction. Are diagnosed and the presence of antibodies using Indirect MAR test on a semen sample.
As can be excreted wife antibodies in the cervix, and are awaiting the arrival of sperm to paralyze the movement.

Infections
Affects negatively the presence of microbes on the number of sperm and their movement and their ability to fertilize. And be the result of toxins produced by microbes, or as a result of a violent reaction from the immune system of the body in the form of cells Sididip and antibodies. Can also lead to severe infections testicular atrophy full, or to sperm duct obstruction.

Source of microbes is either enemy nationality of women to men or from men to women, I believe inflammation elsewhere in the body, such as urinary tract or anus, and so on.

Infections are diagnosed select number Alsididah cells in my sample of semen and prostate. If exceeded the normal limit, we can deduce the presence of microbes. And cells Alsididah not microbes, but are defensive cells of the human body. And in severe cases can make microbes farm, to test their sensitivity to various antibiotics, to choose the right treatment.
Sometimes, it is difficult to distinguish between cells Alsididah and primitive sperm cells, and cells are found naturally in the semen. Certain dyes used to differentiate between them, such as dye "peroxidase" so as not to be misplaced diagnosis.

Congenital malformations
Could create a defect in human sperm prevents them from movement or fertilization. For example, prohibits sperm in some cases of vesicle commonly found on the preface, which contain enzymes dissolving the wall of the egg, making it impossible to penetrate. There are also other congenital defects is concerned with the movement of the sperm, where the defect is in the tail.
Are diagnosed each of these disorder in a special way. For third, tail defects are diagnosed using a microscope-mail, while deficiency is diagnosed vesicle Alokrozumih test "Okrosen" Acrosin. It is important to know that the distortions are allowed within forty percent of the total number of sperm.
Inability to deliver sperm to his place in the body of the wife

Must be deposited semen in a particular place, higher genital tract wife next to the cervix, natural sexual intercourse. If fertilization can not sexually pain disorder. For example, if you happened to ED, will not be delivering semen to his goal. Also, if there very quickly tossed so that ejaculation before the introduction of User to the genital tract, and in the absence of ejaculation, and if any curvature in the penis to prevent entry.
