Female infertility refers to difficulties in conceiving or sustaining a pregnancy despite regular unprotected intercourse. Causes include hormonal imbalances, ovulation disorders, uterine or fallopian tube issues, endometriosis, and age-related factors. Diagnosis involves tests to assess hormone levels and reproductive organ health. Treatments may include medications, surgery, assisted reproductive technologies like IVF, and lifestyle changes. Emotional support is often crucial for individuals coping with female infertility.
