The concept of infertility in medicine is defined as follows: both male and female partners have normal sexual relations without using any contraceptives, and if the female cannot become pregnant after a year, this condition is diagnosed as infertility. Previously, the time frame for diagnosing infertility was set at two years. However, due to the implementation of the two-child policy, the average age of both men and women tends to be higher, so it is generally limited to one year. If there is no pregnancy within this period, it is urgent to go to the hospital for diagnosis and treatment in order to identify the cause early and treat it accordingly, to avoid delaying the condition.
