According to statistics, a pair of normal couples of reproductive age, marital cohabitation can engage in normal sex life, women do not take any contraceptive measures in the circumstances, within one month of about 20% of women become pregnant; three months, about 60 % -70% of women become pregnant; six months, about 75% -80% of women become pregnant; year pregnancy rate of 85%. Therefore, if cohabiting couples married for one year without conception, should be taken seriously enough and should carry out the necessary and reasonable consultation and inspection to both men and women as early as possible to understand the situation fertility.
People often infertility and infertility two words confused, in fact, they have their own meaning.  Strictly speaking, infertility is not pregnancy, is generally believed that cohabiting couples of childbearing age more than two years who did not take any contraceptive measures were never conceived, known as primary infertility; to have had fertility history or birth then a continuous history of more than two years living together, not contraception without a further pregnancy who are known as secondary infertility.  Education is not able to conceive, but can not give birth to normal live births, in the embryo after conception can not stop the normal development of the abortion or pregnancy.
The so-called infertility is due to barriers to sperm and egg occurs and can not form a fertilized egg Ershi woman failed to conceive.  Instead of education was due to embryonic or fetal development occurs in the barrier, although the sperm and egg combine to form a fertilized egg, but did not make embryos in the women's bodies mature.  Infertility or infertility caused by the above reasons may come from man, but also from the woman, or the common causes of both men and women. In general the view that the man because about 25% -40%, female 40% -45% about the reasons of common causes of about 10% -15%, there are 15% -20% for unknown reasons. 
According to The cause of infertility are classified by infertility can be divided into "relative infertility" and "absolute infertility" two.  Relative infertility: this refers to one or both couples for some factors that impede fertility, or reduced fertility caused temporary infertility, after appropriate treatment or after treatment is still not pregnant, such as uterine dysplasia, uterine extreme flexion, or after dumping bent, endocrine disorders, the man oligospermia (sperm count of less than 2 million / ml), the weak azoospermia (low activity) and immune factors, both men and women due to infertility.  Absolute infertility: this refers to one or both couples have serious congenital or acquired anatomical or physiological defects, can not be corrected, or after treatment were still not pregnant.  Congenital disorders, such as the woman's uterus or ovaries and other congenital absence of the man congenitally undeveloped testis, no sperm, etc.; acquired disorders, such as genital tuberculosis or cancer may be serious damage to reproductive capacity, which led to the absolute nature of infertility.
But with the development of medical science, the absolute nature of infertility could be transformed into the relative nature of infertility, while the relative infertility due to miss the best time to cure or misdiagnosis, mis-governance, may also be transformed into the absolute nature of infertility . Thus, in the treatment process, the doctor will focus on different situations, to adopt a different treatment. If it is the absolute nature of infertility, and was treated for a period of time has no effect in patients, should face reality and abandon the treatment, do not run around, a waste of resources.  Relative infertility patients, must be based on that science, scientific inspection, testing methods, with accurate experimental data to illustrate the problem, try to find the reasons for infertility or infertility, and to take positive and effective measures, symptomatic treatment and strive to achieve the purpose of conception.
