Introduction: Infertility etiology and offspring health.

This issue's of Views and Reviews considers the origins of lifetime health established around the time of conception in some prevalent conditions related to infertility. Reviews will look at the effects of advanced paternal and maternal age, the influence of the severe sperm factor, and the impact of some endocrinopathies commonly seen in infertile couples, especially women, like polycystic ovary syndrome, under- and overweight, diabetes, and thyroid disorders. The aim of this Views and Reviews section is to summarize current evidence on the consequences of these conditions on postnatal health to encourage research in this field and the need to develop strategies and preventative measures to reduce or prevent unfavorable outcomes in future generations.
