Primary sterility is referred to when a couple do not succeed in becoming pregnant after one year of sexual relations without protection. Infertility is when a couple do conceive but the gestation does not evolve correctly and does not go to term, in other words it does not result in the birth of a "normal" child.
Between 15 and 17 percent of couples experience fertility problems. The causes may range from the delay in trying for a first child (older mothers), to medical problems such as fallopian tube obstruction, hormone and semen alterations etc.

From the age of 35, fertility decreases significantly, and from the age of 40 the numbers of pregnancies carried to term are extremely low.
