1. What is infertility? A couple who have had normal sexual intercourse without contraception for at least 12 months without obtaining a clinical pregnancy. Those who have never had a history of pregnancy and have not been pregnant for more than 12 months without contraception are called primary infertility; those who have had a history of pregnancy and then have not been pregnant for 12 consecutive months without contraception are called secondary infertility. You should know: infertility is mostly a sub-infertility state, unless the ovarian function is completely declining, congenital hypothalamic amenorrhea, blocked fallopian tubes and other diseases, the general situation of infertility is not completely no chance of getting pregnant day after day, but only a sub-infertility state, it may not be possible to get pregnant one day. There are too many examples of this kind of infertility, long-term infertility after the adoption of a child pregnant; several failed in vitro fertilization suddenly pregnant on their own, ovulation several times without pregnancy, stop but pregnant, and so on, and so forth, so do not despair, active efforts, the baby will come. 2.How high is the probability of infertility? 82% of couples prepare for pregnancy for one year to conceive; 92% of couples prepare for pregnancy for two years to conceive; the total incidence of infertility is 10-12%. The incidence of infertility is very high, but there is still a chance to continue trying to conceive, but you should seek medical attention when appropriate. 3.How long has it been preparing for pregnancy without pregnancy need to be checked? <35 years of age for one year of infertility needs to be checked for infertility causes; female partner age >36 years of age for 6 months of infertility needs to be checked for infertility causes; those with known diseases that may cause infertility: azoospermia, pcos, amenorrhea, history of ovarian surgery need to be evaluated for fertility as early as possible. Therefore, not all people have equal chances of conceiving, and older age and diseases affect fertility. If you are infertile, you should seek medical attention in time to avoid delay. 4. How much does age affect fertility? Seven couples between 30-34 years old have one pair of infertility; five couples between 35-39 years old have one pair of infertility; four couples between 40-44 years old have one pair of infertility; after 50 years old, most women lose their fertility. The older you are, the lower your chances of conception. Make a fertility plan as early as possible while you enjoy life. Some things are just too good to lose! 5. Is infertility just a woman’s problem? Infertility is a matter of both husband and wife; men and women have equal influence on the occurrence of infertility; the cause of infertility should be investigated in men first, because infertility tests should be simple before complicated, and it is more convenient for men to investigate. Conception requires both partners to provide sperm and eggs respectively, so it is wrong to investigate only the female partner or the female first for infertility.
