Although the effect of advanced maternal age on obstetric and neonatal morbidities is well established, the effect of advanced paternal age needs additional exploration in association with adverse reproductive outcomes. Some studies suggest that the sperm of fathers with advanced age harbor germline mutations that influence reproductive, neonatal, and adult health outcomes of the progeny. Data on the contribution of advanced paternal age to spontaneous abortion, postconceptual age, birth weight, and neonatal mortality depends on the population and the design of the study. There is stronger evidence that advanced paternal age contributes significantly to congenital malformations and the health of the offspring in adolescence and adulthood with an increased risk of cancer, neurologic disorders, and cardiac diseases. In this review, we summarize the results of different studies that address the effect of advanced paternal age on reproductive outcomes and the origin of illnesses in adulthood. We also discuss possible mechanisms and theories behind these potential associations.

Limited awareness of adolescents in preconception health may be addressed through school education. The aim of this intervention is to assess preconception health awareness among adolescents in Lebanese high schools and to test the effectiveness of a one-time educational session in improving preconception knowledge. The intervention consisted of a 30-minute educational session about good practices in preconception health, developed by the National Collaborative Perinatal Neonatal Network's (NCPNN) research team. A convenience sample of high school Lebanese students in grades 10 to 12, aged 14 to 26 years old, from 70 private and public schools in all six Lebanese provinces, participated in the intervention in 2011 and 2012. A multiple-choice questionnaire administered prior to and 2 months after the session was used to assess knowledge improvement among the students. A total of 7,290 students were e...
