The number of women undertaking a pregnancy in late reproductive age is increasing. It is unclear if age of 35 to 40 years constitutes a real biologic limit to reproduction or if unfounded social prejudices play a role. Many publications present advanced age as a significant risk factor for the mother and fetus. Only recent data can be considered because of constant advances in perinatal medicine. Furthermore, many studies are limited by the small sample size and by the lack of control groups and correct statistical analysis. Reproductive outcome is influenced by obstetric, maternal, social and psychological factors. The most recent data obtained on large series of women after control for confounding variables have demonstrated that advanced maternal age is a risk factor for fewer complications than generally believed, such as probability of conception, frequency of chromosomal anomalies, occurrence and consequences of hypertension and diabetes, type of delivery, and maternal and fetal mortality. In the absence of preexisting maternal disease and if correct care is provided by health personnel the prognosis for a pregnancy in an older woman is not greatly different from that of a younger one. By adopting an appropriate attitude the physician can reduce the mother's excessive preconceived concerns, thus allowing the delivery of correct prenatal care and a serene pregnancy.
