Pregnant Woman with Fetus at 23 Weeks, Lateral View (Caucasian Skin)

Description

Seen from the side, the maternal torso is rendered semi-transparent so that the gravid uterus fills the lower abdomen and pelvis at approximately 23 weeks of gestation. The fetus lies curled within the amniotic cavity in a cephalic-leaning position, head directed inferiorly toward the pelvic inlet, limbs flexed against the trunk, with the coiled umbilical cord running from the ventral abdominal insertion toward the placenta on the uterine wall. Beneath and behind the uterus the view shows the cervix and vagina, the urinary bladder compressed anteriorly behind the pubic bone, and the rectum and sacrum posteriorly, while the fundus rises above the level of the umbilicus and displaces the maternal abdominal wall forward. A lateral projection is the clearest way to convey second-trimester spatial relationships: fundal height relative to the umbilicus, anterior displacement and reduced capacity of the bladder, and the increased lumbar lordosis that accompanies the shifting centre of gravity. At 23 weeks the fetus is nearing the threshold of viability, making this stage central to discussions of preterm birth, antenatal corticosteroid timing and neonatal intensive care counselling. The visible cervix and lower uterine segment also support teaching on cervical length assessment, cervical insufficiency and placental localisation on ultrasound. The image suits obstetric and midwifery teaching sets, antenatal class handouts, and patient-facing material explaining what happens during the sixth month of pregnancy, including common symptoms such as urinary frequency and back pain. As part of a week-by-week series it works for publishers building gestational timelines, for apps and websites aimed at expectant parents, and for journal or textbook figures illustrating fetal position and maternal anatomy in the second trimester.
