Infertility is defined as failure to conceive after one year of regular, unprotected sex(at least twice in a week ) with the same partner. The chance of conception is 20% per month. On average nine out of ten will conceive during their first year while around one in twenty will conceive within two years.
I prefer to call “Sub fertility” rather than infertility, because there is chance less to conceive naturally, unless and until there is small rudimentary uterus, absent ovaries and both blocked fallopian tubes or if the male has no sperms . There are various causes of sub fertility.
