Why sexual health is important

Good sexual health is fundamental to overall health and wellbeing across every stage of life. It can affect and be affected by other aspects of health, including physical, mental and emotional health.

Untreated STI can cause major health problems, like infertility, ectopic pregnancy, preterm birth, neonatal death, and pelvic inflammatory disease.
