Signs of Infertility
According to the National Center for Health Statistics of the Centers for Disease Control and Prevention 2002 about 12 percent of women (7.3 million) in the United States aged 15-44 had difficulty getting pregnant or carrying a baby to term.Infertility can be termed as the state in which the ability of a person to conceive or have offspring is the diminished greatly. Infertility is also defined in specific terms as the failure to conceive after a year of regular intercourse without contraception. Irreversible infertility is also referred to as sterility. In most cases couples achieve pregnancy within the first six months of trying. Overall, about 80 -85% of couples become pregnant after 12 months of unprotected intercourse. Over the next 36 months, about 50 percent of the remaining couples will go on to conceive spontaneously.
It is totally wrong to say that infertility is on woman’s part only as in only about one-third of cases infertility due to the woman (female factors). In another one third of cases, infertility is due to the man (male factors). The remaining cases are caused by a mixture of male and female factors or by unknown factors.
Causes of male infertility include abnormal sperm production or function, impaired delivery of sperm, general health and lifestyle issues, and exposure to certain environmental factors. Women aren’t the only ones with a hormone cycle. Men have a hormone cycle, too! But there are big differences. For instance, instead of having a month-long hormone cycle like gals, guys go through an entire hormone cycle in a single 24 hours. Researches show that the quality of the male sperm can go down, in accordance with his hormone cycle. The lower sperm quality of a man can significantly reduce his ability to impregnate.
