If you have tried to have a baby for two years in vain, it is called infertility. The term, when you prevent conception or you don't because it is no matter for you to conceive or not, is not included. I t means two years since you begin trying to conceive eagerly. However, if you have kept taking your basal body temperature and tried hard to be pregnant for one year, and it doesn't seem to work, I recommend you to go to the hospital. Since there are many factors of infertility, please refer to the table for judgement in which they are combined. And those who are oversensitive to cold and have obesity, tend to become infetile constitutionally. Try to improve your physical constitution before going to the hospital.�@
Now, after you have decided to go to the hospital, the next thing you should do is to choose the hospital and your doctor. If you make a mistake at this point, you might lose a chance to succeed. Even if it might take longer, you should make a choice very carefully.
Once you choose , be sure not to change a hospital easily. Some people continue going this and that hospital because the doctor has a good reputation or appears in the newspaper. But they cannot be successful. This is called " Doctor shopping" and it is the worst way of taking treatment. A doctor ,who is also a human, will be the most enthusiastic when mutual confidence grows between him and his patient. Moreover, if you change a hospital for a short period, it would be difficult to analyze the present condition owing to dispersion of your precious data.

At least, you should keep taking your basal body temperature before going to the hospital, and make sure to have the table with you there.

Let me tell you about the foundation of infertility treatment. Although there are various kinds of treatments for it, following three main points are the most important.
The first is whether you ovulate or not, and whether the quality of an oocyte is good or bad. Some oocytes are immature and others are overmature,and both result not to fertilize. So it is important that an ovum in exactly suitable maturity has come out. The second is whether an oviduct is patent or not. Even if ovulation is successful, an ovum cannot meet a sperm when the fallopian tube is narrow or obstructed.
The third is the condition of the semen. It is a big matter whether a sperm can come up to ampulla of fallopian tube and meet the ovum. Since these important three are more than 90% of the causes of infertility, it is general that they are examind at first.
