Infertility exists when you and your life partner are unable to conceive a child even after twelve  months of continuous ual intercourse without birth control methods. Infertility can be because of a single cause in either your body parts or your partner's, or a combination of factors that may prevent a pregnancy from occurring or continuing.

Infertility is different from sterility. Being sterile means you will never ever conceive a child. With sterility, you or your partner has a physical problem that precludes the ability to conceive. A diagnosis of infertility simply means that becoming pregnant may be a challenge rather than an impossibility.

Causes of male infertility
There are a number of causes for male infertility which can result in impaired count or mobility, or impaired ability to fertilize the egg. The most common causes of male infertility include abnormal production or function, impaired delivery of , conditions related to a man's general health and lifestyle, and overexposure to extreme environment:

Abnormal production or function. Most cases of male infertility are due to abnormalities, such as:

  • Impaired shape and movement of . must be properly shaped and able to move rapidly and accurately toward the egg for fertilization to occur. If the shape and structure (morphology) of the are abnormal or the movement (motility) is impaired, may not be able to reach the egg.
  • Absent production in testicles. Complete failure of the testicles to produce is rare, affecting very few infertile men.
  • Low concentration. A normal concentration is greater than or equal to 20 million per milliliter of semen. A count of 10 million or fewer per milliliter of semen indicates low concentration (subfertility). A count of 40 million or higher per milliliter of semen indicates increased fertility.
  • Varicocele. A varicocele is a varicose vein in the scrotum that may prevent normal cooling of the testicle and raise testicular temperature, preventing from surviving.
  • Undescended testicle (cryptorchidism). This occurs when one or both testicles fail to descend from the abdomen into the scrotum during fetal development. Undescended testicles can cause mild to severely impaired production. Because the testicles are exposed to the higher internal body temperature compared to the temperature in the scrotum, production may be affected.
  • Testosterone deficiency (male hypogonadism). Infertility can result from disorders of the testicles themselves, or an abnormality affecting the hypothalamus or pituitary glands in the brain that produce the hormones that control the testicles.
  • Klinefelter's syndrome. In this disorder of the chromosomes, a man has two X chromosomes and one Y chromosome instead of one X and one Y. This causes abnormal development of the testicles, resulting in low or absent production. Testosterone production also may be lower.
  • Infections. Infection may temporarily affect motility. Repeated bouts of ually transmitted diseases (STDs), such as chlamydia and gonorrhea, are most often associated with male infertility. These infections can cause scarring and block passage. Mycoplasma is an organism that may fasten itself to cells, making them less motile. If mumps, a viral infection usually affecting young children, occurs after puberty, inflammation of the testicles can impair production. Inflammation of the prostate (prostatitis), urethra or epididymis also may alter motility.
