Conclusion
Our study provides a comprehensive estimation of the TTP among Chinese
couples of reproductive age. Over half of women aged <35 years
would conceive within 1 year, the proportion of which increased to 80%
at 2 years. Conversely, the probability of natural conception among
women older than 35 years was only half that within 2 years. Along with
the TTP distribution in Chinese couples, this study also detected
related risk factors for fecundity such as age, toxic exposure, and
socioeconomic status. Although the diagnosis and treatment of
subfertility or infertility are becoming more accurate and less
invasive, there remains
a
need to explore the overall fecundity of couples in order to guide
clinicians toward the appropriate timing of treatment. Hence, the
results of our study provide important information for policy makers to
improve sexual health education for couples of reproductive age.
