Causes of male infertility
Infertile couples have been trying to get pregnant but seemly hard to get success. Many couples automatically attributed the causes of infertility to women. Actually forty percent of fertility issues are male-related problems. In men, there are many different causes of infertility, including trauma or sports related injuries, hormonal disorders, illness, medications, or anatomical problems.
Varicocele: Varicocele affectes about 40 percent of infertile men. It is caused by enlargement of the veins in the scrotum.If these veins are enlarged it can cause the temperature to increase. Increased scrotal temperature can affect sperm production and sperm quality.
Cryptorchidism: If the testes do not properly descend into the scrotom this is called cryptorchidsm. Cryptorchidism is fairly common in premature births and occurs in full term births at a much lesser rate. Usually this resolves itself within a few weeks, but sometimes corrective surgery is needed. Cryptorchism can seriously impair fertility rates. If both testes are affected the chance of a successful pregnancy is very small.
Disease or illness: Diseases such as cystic fibrosis can affect male fertility. Men who have undergone chemotherapy or had sexually transmitted desases may also be at greater risk of infertility.
Obstructions in the reproductive tract: Obstructions in the male reproductive system is another common cause of infertility. Men with obstruction problems are usually making sperm but it is not making its way outside of the penis. Common causes of obstructions are urinary tract infections, scarring from sexually transmitted disease, injury, vasectomy or anatomical defects.
Damage: an accident or injury may cause damage, and result in infertility of the male reproductive system.
Hormone deficiency: the male hormone testosterone can affect sperm production, such as manufacturing defects. Doctors usually ask the beginning of puberty, because age of male puberty can be a indicator of hormonal imbalance.
Drugs: Many drugs affect fertility and lead to sexual disfunctions. It is important for physicians to assess the possible impact on his fertility.
Retrograde ejaculation: Retrograde ejaculation causes the bladder nerves or muscles do not work. What happens is sperm is transported backwards into the bladder instead of forward and out through the penis. Sometimes men ejaculate because of the cloudy urine.
If you have infertility problems, it is important that both partners to be tested. The doctor will do a thorough physical examination and evaluate the man's sperm. Men may be uncomfortable going in for an exam but it is really necessary that both partner's be evaluated during a fertility work up. Treatment will be differ from the causes of the infertility.
