Infertility affects one in every ten American couples. Cause of infertility includes a wide range of physical as well as emotional factors. Approximately 30% to 40% of all infertility is due to the "male factor". The "female factor" is responsible for 40% to 50% of infertility of couples. The remaining 10% to 30% may be caused by contributing factors in both partners, or no cause can be identified.
For a man, being the infertile factor can be quite embarrassing. However, they must keep their heads high, wish for the best and do their homework. One reason for infertility is whether or not they have good quality of sperm cells. There are five factors that affect this. The first is to have a normal sperm count. Second, the number of sperm cells per milliliter of semen is taken into affect. This is called concentration. Also, motility, the ability to "swim", and speed, number of sperm that are the fastest swimmers are taken into consideration.
The last factor tested is morphology, which measures the size and shape of sperm cells. The higher the percentage of misshapen sperm, the less likely fertilization can take place.
Other than the quality of the sperm cells, many other factors may interfere with how fertile an individual may or not be. Such factors include, infections (viral and bacterial), Varicoceles, and Hypogonadism. An individuals everyday lifestyle also can factor fertility. Alcohol, drug use (especially heavy use of marijuana), herbs and supplements, smoking, heat, and stress are just a few examples. Also prescribed medications can alter sperm cells. Tagamet, used to treat stomach ulcers and reflux disease will increase a man's level of prolactin. Also, different antibiotics alter, destroy and kill off sperm such as minocycline, marcroliases, and sulfasalazine.
