Infertility is commonly defined as the inability of a couple to conceive a child after one year of engaging in regular, unprotected sexual intercourse. This condition can arise from a variety of factors, including complications related to either partner or a combination of issues that interfere with the natural process of achieving pregnancy. It's important to recognize that infertility affects many couples and can stem from various medical, anatomical, or hormonal challenges. Understanding the underlying causes is crucial for exploring effective options and potential treatments for those struggling with this condition.
