It is generally accepted that couples of childbearing age who do not use contraception have an average of 25% chance of becoming pregnant per menstrual cycle, 50% should become pregnant within 3 months of marriage, 72% should become pregnant within 6 months of marriage, and 80% to 85% should become pregnant within 12 months of marriage, while infertility may affect about 10% of couples of childbearing age. Therefore, if you are married for more than one year, have regular sexual intercourse, do not use any contraceptive measures, and your spouse cannot get pregnant or can conceive but fails to conceive and deliver, you should consider the possibility of infertility, which is collectively referred to as infertility in medicine, including male infertility and female infertility (pregnancy).
