There are several reasons for infertility in men. Fortunately, once diagnosed, it is possible to address some of these causes.
If you are worried about your health or any of the following conditions, you should speak as soon as possible to your healthcare professional.
The abnormal sperm
Several male fertility problems may be associated with abnormal sperm. S Only a few hundred sperm, among the millions who are normally deposited in the vagina, s’approchant of the egg and will have a chance to fertilize. Several factors play a role in the success of sperm:
the sperm count (number of sperm);
sperm motility (ability to move),
progression forward (quality of movement)
the size and shape of sperm.
A failure of one of these factors can cause fertility problems. Although the sperm count is important, motility and progression forward sperm appear to be even more crucial in determining whether the sperm can fertilize an egg. Despite the low numbers of sperm, several men whose sperm is of good quality can still be fertile. Your doctor can perform a simple analysis of semen in his office to determine the quality of sperm.
A wide variety of conditions may play a role in the cause abnormal sperm.
Age
The effect of advancing age on male fertility is not well known, but some recent data indicate that it may be a factor. In general, a male fertility starts to decline to 35 years although it is possible that sperm quality starts to decline. Moreover, it is possible that the mobility of sperm declines with age. The rates of fertilization are usually above 60% for men under 39 years, but for older men, the rates are reduced to just over half.
Immunological disorders
Some problems of the immune system can bring the body to treat sperm as if they were foreign bodies The immune system can then produce antibodies to fight and destroy sperm. In the general population, it occurs in only 1% to 2% of men but in this small population, fertility is reduced by 40%.
claries against cancer
The chemotherapy and radiation may contribute to some problems with fertility as the site of treatment, medication and dosage used. Unrest particularly important may be caused by a number of chemotherapy treatments for platinum-based, as in the removal of genitals and adjacent areas (such as testicular cancer). For more information on how to preserve your fertility before starting treatment against cancer, talk to your oncologist or a specialist in fertility.
Sexually Transmitted Infections (STI)
The ITS can damage body parts that carry sperm into the reproductive tract Talk to your doctor about how ITS can affect your fertility, how to reduce your risk and you have to undergo tests.
The disease, lifestyle and environmental factors
Temperatures higher
Prolonged exposure to high temperatures such as hot baths and saunas can reduce sperm production, like wearing tight underwear.

Little black spots begin to speckle the wall, as a musty smell fills the room winding its way into your unsuspecting nostrils.  You walk across your living room carpet with bare feet and sense an unwelcome sensation of moistness seeping between your toes.  Suddenly realizing that water is penetrating the security of your home like a burglar in the night, your first impulse is a sense of low-level panic!  Where is the moisture coming from  Then, it hits you like a freight train.   Those specks on the wall are mold!

Frantically, you begin searching for the source of leakage into your home.  Lifting up the carpet, you notice water is all over the floor-base and sections of the wood molding are dry while one long patch under the speckled portion of the wall is completely saturated.  The problem could be that the actual leakage is coming from within the wall and not from an easily detectable area such as a patio doorway.  You wonder how long this has been happening and what can be done about itfast!  You and your wife are elderly and maneuverability is difficult, so tackling this problem could be beyond your physical capabilities.  What can you do

You and your wife have been having sinus problems over a six-month period with constant attacks of flu-like symptoms.  Is there a connection between your discovery of mold contamination and the health problems you are experiencing  Is mold exposure hype or really dangerous (more…)
