What does Hegar's sign indicate?

• A. Softening of the cervix
• B. Changes in fetal heart rate
• C. Softening and compressibility of the lower uterus
• D. Darkening of the areola

Answer: (C)

Hegar's sign is an important clinical indication during pregnancy, specifically referring to the softening and compressibility of the lower segment of the uterus. This sign typically becomes noticeable around the sixth to eighth week of gestation and is caused by hormonal changes that lead to increased blood flow and relaxation of the uterine tissue. The presence of Hegar's sign provides confirmatory evidence of early pregnancy and is often assessed during a pelvic examination.

This physiological change is important for healthcare providers as it helps them confirm the viability of the pregnancy and assess its progression. Recognizing Hegar's sign contributes to the overall understanding of reproductive health and fetal development during the early stages of pregnancy.
