Essential Fertility Diagnostic Tests Explained

Diagnostic tests like Day Three Blood Work (FSH, AMH), ultrasound for antral follicle count, HSG for uterine/fallopian health, and semen analysis help evaluate fertility. These tests, completed in 2-3 weeks, guide treatment plans and identify issues like blocked tubes or low sperm quality.
