Introduction
The pubis is the most prominent bone in the genital region when a woman lies supine. If you palpate the lower abdomen with your hand, you will feel a relatively hard nodule—this is the pubic tubercle; the two portions extending laterally from the pubic tubercle constitute the pubis. Some women experience pubic pain due to pubic symphysis diastasis—a separation of the pubic bones—caused by fetal development during pregnancy.
Pregnancy—a ten-month journey—is an exceptionally demanding process. Whether in the first or third trimester, it brings numerous physical discomforts to the expectant mother. In particular, during the third trimester, as the fetus continues to grow, many women experience low back pain and soreness, and may even develop pubic bone pain—potentially compromising maternal health.So, where exactly is the pubic bone located? Below, we address this question.
Where Is the Pubic Bone Located?
The pubic bone is the most prominent bony structure in the lower abdominal region when a woman lies supine. If you gently palpate the lower abdomen with your fingers, you will feel a firm, rounded bony prominence—the pubic tubercle. Extending laterally from this tubercle on both sides are the left and right pubic bones. During pregnancy, fetal growth may cause pubic symphysis separation in some women, resulting in pubic pain. The pubic bone serves to protect internal reproductive organs, and the pubic symphysis plays a crucial role in pregnancy and childbirth. Therefore, prior to delivery, it is advisable for pregnant women to undergo ultrasound assessment of fetal size and measurement of the pubic symphysis distance.
Knowledge Extension: How to Alleviate Pubic Pain During Pregnancy
1. Avoid Excessive Strain
When pubic pain occurs in late pregnancy—and especially if severe—it may become painful even to walk. Pregnant women should therefore move deliberately and gently: avoid sudden or large-amplitude movements, whether walking or sitting down. While walking, supporting the abdomen with one’s hands can help reduce pressure on the pubic bone and thereby alleviate pain.
2. Strengthen Pelvic Floor Muscles
To address pubic pain during pregnancy, women may perform gentle pelvic floor muscle exercises while lying in bed. Begin by relaxing the body and lying supine. Slowly bend both knees, then gradually spread the legs apart, and finally bring them back together—repeating this sequence several times. This helps strengthen the pelvic floor muscles. However, because the body becomes increasingly heavy in late pregnancy, fatigue may set in quickly during exercise; thus, women should always exercise within their physical limits.
The above outlines the anatomical location of the pubic bone. We hope this information proves helpful.
