Infertility is not for women only. About 30 percent of infertility cases involve a male factor and about 20 percent involve factors from both partners. With these statistics, the male partner is either the sole or a contributing cause of infertility in half of the infertile couples. Like those of female infertility, male causes of infertility are categorized, usually into seminal and structural abnormalities.
Seminal abnormalities include low or poor sperm production. Both the quantity and the quality of sperm are important for conception to occur.
There is no sperm found in the efaculation in an Azzospermia. When the sperm count is low it is called Oligospermia. If there is not enough sperm then the egg has less of a chance of being fertilized.
Not only is the number of sperm important, but so is the quality. Sperm quality is judged according to their motility (ability to move) and their morphology (structure). Without good motility, sperm cannot make that long swim up to an awaiting egg. If damaged, they can’t swim properly or penetrate an egg.
Abormalities in Structure
Things like illness, surger, and abnormalities at birth can cause infertility in males. The main cause in male infertility includes the following:
The network of dilated varicose veins in the scrotum is known as Variocele and is the most common cause of male infertility. Almost ninety percent of variocele are in the left side.
When teststicals do not drop into the scrotum it is called undescended teststicals. If they are not taken from the abdomen the production of sperm is impaired.
Surgeries such as hernia, prostrate, bladder, neck, and testicular cancer.
The impairment of sperm’s ability to travel to the penis in ejaculation is called Epididymis. Surgery and birth defects can both cause this problem. But there are times when it is not known.
Sterilization that is voluntary keeps the sperm from joining the ejaculate.
What Medical Disorders Affects Infertility in Males
Several medical conditions can also harm male fertility. The most common are infections and injury. In addition, cystic fibrosis, sickle-cell disease, and renal disease can impair a man’s ability to father a child. Also a variety of drugs and environmental agents can hamper male fertility.
Several medical conditions, in particular, infections, can affect a man’s ability to produce a child. In fact, any infection or fever can impair sperm development and affect the ability to conceive for three months! So if your doctor orders sperm analysis, don’t forget that one test result is not always conclusive.
Testicular trauma or torsion
Testicular trauma is the most common cause of inaccurate tests. Torsion happens when the testicles become wrapped in the cord. The quick interruption of blood to the testicle can cause swelling and surgery is required to repair the testicle. If treatment is not done then it will die.
Medications, toxins and illicit drugs
A variety of drugs-therapeutic and illicit-can have detrimental and sometimes devastating effects on male fertility. These can range from impotence to sterility. In addition, exposure to environmental and occupational toxins can impair testicular function.
