Around 3–5% of pregnant women at term (37–40 weeks pregnant) have a breech baby. [2] Due to their higher than average rate of possible complications for the baby, breech births are generally considered higher risk. [3] Breech births also occur in many other mammals such as dogs and horses, see veterinary obstetrics.

Although described as "morning sickness," pregnant women can experience this nausea any time of day or night. The exact cause of morning sickness remains unknown.

According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
