Infertility is the inability to conceive after one year of regular, unprotected sexual activity or the inability to carry a pregnancy to term.
On average, between 10% and 20% of couples in Ireland are unable to conceive after one year of trying. Women reach the peak of fertility in their early twenties. Couples in their twenties who are in good physical health and engage in regular sexual activity have about a 25% to 30% chance per month of conceiving. Women in their thirties, particularly those over the age of thirty-five, have less than a 10% chance per month of becoming pregnant.
