What causes Hyperviscous sperm?
Hypofunction of the prostate or seminal vesicles causes abnormal viscosity of seminal fluid. Infection and high levels of seminal leukocytes may also result in the development of SHV. Oxidative stress and biochemical and genetic factors can furthermore contribute to this condition.
Is viscous sperm good?
Viscosity– This term refers to the consistency or thickness of the seminal fluid. Low or moderate viscosity is considered normal and flows easily. If the consistency is too thick, the semen has a harder time leaving the reproductive track.
What is a good sperm count?
Normal sperm densities range from 15 million to greater than 200 million sperm per milliliter of semen. You are considered to have a low sperm count if you have fewer than 15 million sperm per milliliter or less than 39 million sperm total per ejaculate.
What is the average sperm volume?
1.5 to 5.0 milliliterNormal Results The normal volume varies from 1.5 to 5.0 milliliter per ejaculation. The sperm count varies from 20 to 150 million sperm per milliliter. At least 60% of the sperm should have a normal shape and show normal forward movement (motility).
Is healthy sperm thick or runny?
Normally, semen is a thick, whitish liquid. However, several conditions can change the color and consistency of semen. Watery semen can be a sign of low sperm count, indicating possible fertility problems. Ejaculating thin, clear semen may also be a temporary condition with no serious health concerns.
Which sperm is more powerful?
Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind.
What sperm count is infertile?
The authors conclude that a sperm count of less than 13.5 million per mL, motility less than 32 percent, and less than 9 percent normal morphologic sperm forms predicted infertility (see accompanying table).
How much sperm is enough for pregnancy?
Fertility is most likely if the semen discharged in a single ejaculation (ejaculate) contains at least 15 million sperm per milliliter. Too little sperm in an ejaculation might make it more difficult to get pregnant because there are fewer candidates available to fertilize the egg.
How do I read my sperm test results?
Anything less than 15 million sperm per milliliter, or 39 million sperm per ejaculate, is considered low. A low sperm count is often referred to as oligospermia. A high, or above average, sperm count is over 200 million sperm per millimeter. You can determine your sperm count through a semen analysis.
At what age do men stop producing sperm?
Although men never stop producing sperm throughout their lives, sperm production does begin decreasing after age 35. Motility, volume and genetic quality of sperm of older men are less likely to achieve a successful pregnancy even in younger women.
How many times should a man release sperm in a week?
It is completely healthy to ejaculate more or less than three times a week! The average ejaculation frequency for men ranges from two to seven times a week, which is a pretty wide gap. So it's clear that there's no right or wrong answer, nor are there any significant health risks associated with ejaculation frequency.
Is high sperm volume good?
It is the opposite of hypospermia (low semen volume), and is generally defined in humans when the ejaculate is over 5.5 ml. In most cases, hyperspermia does not interfere with fertility. If the semen contains an adequate concentration of healthy sperm, higher volumes actually enhance fertility, respectively.
Can I get pregnant with high viscosity sperm?
Objective. Patients with highly viscous semen may have decreased fertility since spermatozoa become trapped in the coagulate.
How do I know if my sperm are good?
Having your semen tested by a lab is the best way to know whether you're fertile. This type of test is called a lab semen analysis. A lab semen analysis checks: Semen volume.
Does thick sperm affect fertility?
When sperm is expelled in ejaculation it should have a thick consistency. However, a very dense ejaculate can affect other seminal quality parameters such as sperm motility. Therefore, abnormally thick semen could lead to male fertility problems.
Why is sperm liquidy?
The concentration of sperm is what makes the semen cloudy and thick, so if your ejaculate is watery it is possible that you have a low sperm count. This doesn't mean you're infertile (so precautions to prevent pregnancy still need to be taken for couples that don't want to get pregnant).
What is the process of spermatogenesis?
The spermatogenesis is the process by which spermatozoa are generated in the testes. The spermatozoa travel male reproductive tract during which they meet many substances secreted from reproductive organs. One of the substances is epididymal protease inhibitor (EPPIN) that is involved in the post-testicular maturation including capability of fertilizing the eggs. The expression of EPPIN gene was investigated in various tissues of sexually mature and regressed male Syrian hamsters by reverse transcription polymerase chain reaction (RT-PCR). The EPPIN gene was identified in the testis and epididymis of the male Syrian hamsters and compared to the genes reported previously. There was no expression of EPPIN gene in reproductively and completely regressed testes of Syrian hamster. These results suggest that the expressions of the EPPIN gene are associated with the reproductive capability in the Syrian hamsters.
Where are sperms produced?
The morphogenetically matured spermatozoa (sperm) are generated in the testes by the spermatogenesis. They travel male reproductive tract with many substances secreted from the accessory reproductive organs. One of the substances is the semenogelin (SEMG) released from the seminal vesicles that is involved in the post-testicular maturation. The expression of SEMG gene was investigated in seminal vesicle tissues of sexually matured and regressed male Syrian hamsters by reverse transcription polymerase chain reaction (RT-PCR). The SEMG gene was uniquely identified in the seminal vesicles of the matured Syrian hamsters and compared to the genes reported previously. But the expression of SEMG gene was not observed in reproductively and completely regressed testes of Syrian hamsters. These results indicate that the expressions of the SEMG gene are related to the reproductive capability in the male Syrian hamsters.
What causes infertility in men?
Infertility is a worldwide problem affecting about 15% of couples trying to conceive. Asthenozoospermia (AZS) is one of the major causes of male infertility, diagnosed by reduced sperm motility, and has no effective therapeutic treatment. To date, a few genes have been found to be associated with AZS in humans and mice, but in most of cases its molecular aetiology remains unknown. Genetic causes of AZS may include chromosomal abnormalities, specific mutations of nuclear and mitochondrial genes. However recently, epigenetic factors, altered microRNAs expression signature, and proteomics have shed light on the pathophysiological basis of AZS. This review article summarises the reported genetic causes of AZS.
Where does decondensation occur in spermatozoa?
The decondensation of the nucleus of human spermatozoa normally occurs in the oocyte and allows the formation of a male pronucleus. This phenomenon must occur rapidly at this stage but is excluded during all the preceding stages of maturation of the sperm and during travel through the female genital tract, as otherwise it would loose its genome. The compactness of the sperm nucleus has been studied in an attempt to understand the biochemical substratum involved in the condensation/decondensation processes. This review is limited to human sperm, as the decondensation process seems, up to a point, rather different from that described in animals because of different susceptibilities to decondensing reagents and different protein ratios.
Is seminal analysis a predictor of male reproductive potentiality?
Abstract Background : It is a scientific fact today that routine seminal analysis is only a poor predictor of male reproductive potentiality , so that there is an increased need for finding out new functional tests in the assessment of male infertility . Objective : The aim of the present study was to investigate the predictive value of sperm chromatin integrity assays as a complementary tool to assist in diagnosis of infertility . Method : This study was carried out between January 2013 and November 2013 including one hundred (100) selected infertile men who attended to fertility Center in Al-Sadr Medical City . The study also included twenty (20) healthy fertile volunteers as a control . Aniline blue (AB) staining was used to differentiate between normal condensed chromatin (unstained) and abnormal decondensed chromatin (blue), while toluidine blue (TB) was used to differentiate between normal intact sperm DNA (blue) and abnormal damaged sperm DNA (purple), this is the first study in Iraq that employed (TB) to assess sperm DNA fragmentation . Results : The results showed that there was a high significant difference (p<0.01) in sperm chromatin decondensation and sperm DNA damage between infertile and fertile men . The study also revealed a significant difference (p<0.05) in sperm DNA damage between normozoospermic and fertile men, but no significant difference (p>0.05) was found in the sperm chromatin condensation . Both sperm chromatin condensation and sperm DNA damage showed a significant positive correlation with sperm morphology, and a significant negative correlation with sperm concentration, motility and progressive motility.
What is hyperviscosity syndrome?
In adults, hyperviscosity syndrome is often caused by an underlying condition such as leukemia. The condition needs to be properly treated first to see if this improves the hyperviscosity. In severe situations, plasmapheresis may be used.
What are the symptoms of hyperviscosity?
Other symptoms of hyperviscosity syndrome include: abnormal bleeding. visual disturbances. vertigo. chest pain.
What is the normal blood viscosity?
Normal values are usually between 1.6 and 1.9. During treatment, the goal is to lower viscosity to the level needed to resolve an individual’s symptoms.
How does hyperviscosity affect children?
In children, it can affect their growth by reducing blood flow to vital organs, such as the heart, intestines, kidneys and brain.
What happens if a baby has hyperviscosity syndrome?
If your baby’s doctor determines that your baby has hyperviscosity syndrome, your baby will be monitored for possible complications. If the condition is severe, your doctor may recommend a partial exchange transfusion. During this procedure, a small amount of blood is slowly removed.
Is hyperviscosity a risk factor for a baby?
Also, those who have a history of serious bone marrow conditions are at a greater risk of developing hyperviscosity syndrome .
Can a baby have hyperviscosity?
If your baby has a mild case of hyperviscosity syndrome and no symptoms, they may not need immediate treatment. There’s a good chance for full recovery, especially if the cause appears to temporary. If the cause is related to a genetic or inheritable condition, it may require long-term treatment.
