Causes For Male Infertility



Causes for male infertility


In about 30% - 40% of the couples, men found to be the only contributing cause for infertility problems and in about 50% of the cases, the cause of male infertility cannot be found. A lack of sperm is the cause of about 10%-15% of men who are infertile. A man sperms should meet with woman egg to conceive a baby. 

During sexual intercourse, the penis delivers sperm to the female reproductive tract through ejaculation. The more common cause for male infertility can be the blockage in male reproductive organs, hormone imbalances or the problem with testicles and its working.   


Find below the causes for male infertility

Ozoospermia – Is one of the male infertility causes that at about 15% infertile men face.  Ozoospermia is a condition of no sperm count that completely lacks sperm. Blockage of sperms movement or a hormone imbalance can cause azoospermia.



Oligospermia – Is a condition of low sperm count (low sperm concentration) in the ejaculate. Having low sperm count may suggest that it is difficult to get pregnant but does not mean that it is hard to become pregnant and many men with low sperm counts conceive without having any trouble and not knowing they have low sperm counts. The most common causes for this can be a varicocele (an enlarged vein in the testicle), which can be treated surgically.

Genetic abnormalities are found in men with severe oligospermia.  Missing regions in the Y chromosome found in 15% of men with no sperm counts and 6% of men with low sperm counts.

Low sperm count can be an indication of genetic condition.  2% of men with low sperm counts and 15-20% of men with no sperm counts hold chromosomal abnormalities noticed by cytogenetic analysis (karyotype). This includes conditions such as Klinefelter syndrome (47, XXY) and the commute of genetic materials in non-sex chromosomes.  They are detected through blood tests.




There are many conditions associated with low sperm counts.

Varicocele – The condition of an enlarged vein in the testicle, which can be treated surgically.



The consistent use of recreational drugs such as alcohol, cocaine, marijuana or tobacco, hot baths, and fevers from flu’s or infections can lower the sperm counts.



Stress from travelling, work, sleep disorders, or any emotional issues can also lower sperm counts. Generally this becomes reversible upon recovery. 

Obesity, heart diseases, diabetes, chromosome defects, impotence, spinal cord injury, Y chromosome deletions, and sickle cell anemia can also cause low sperm count.

Karyotype anomalies (chromosome defects)

Injury to the testicles or testicles swelling due to infections such as Chlamydia, mumps, or gonorrhea.

Chemotherapy, radiation, and reactions to medications.

Thyroid problems.

Sexually transmitted diseases (STD’s).

Multiple sclerosis.

Surgical procedures such as vasectomy, hernia, and orchiectomy.

Testis cancer and treatment

Organs failure such as liver or renal failure.


Levels of low sperm count (the WHO considered 15million/mL of sperm count to be low for fertile men)

Mild oligospermia                       10 million to 20 million sperm/mL

Moderate oligospermia               5 million to 10 million sperm/mL

Severe oligospermia                   0 to 5 million sperm/mL

Cryptoozospermia                       0 to rare sperm

Azoospermia                               0 sperm                    
         
In some men, the sperm may move too slowly or no movement at all so that the sperms die before they can reach the egg and in some cases the seminal fluid that contains the sperm is too thick for the sperms to move around. This causes in about 10% to 20% of the cases of male infertility. This can be due to natural obstructions within the tubes that carry sperm from the testicles to the penis or due to a vasectomy (surgical procedure that cuts and seals the tubes).

Some men will have problem with an erection (called erectile dysfunction), that makes sex difficult.
 
There is a condition in which sperm moves into the bladder rather than out of the penis (this is called retrograde ejaculation) which can also cause infertility.
