Infertility is a medical condition characterized by the inability of an individual or a couple to achieve pregnancy or sustain a pregnancy to term after a year or more of regular, unprotected sexual intercourse. It can result from various factors, including reproductive health issues in both men and women, hormonal imbalances, age-related factors, or underlying medical conditions. Infertility can be a challenging and emotional experience for those affected, often involving medical interventions, lifestyle adjustments, or assisted reproductive technologies to help conceive.
