Did You Know ?

Did You Know ?

In the fourth week, the embryonic heart starts beating. The neural tube, which becomes the brain and spinal cord, forms. At this point, a woman has likely only been aware of her pregnancy for one week.

Did You Know ?

In the seventh week after conception, networks of neurons produce brain waves that have been recorded as early as 6 ½ weeks after conception. The embryo spontaneously moves his arms, hands, and legs, and may even hiccup. The embryo’s heart now has all four chambers.

Did You Know ?

By the seventeenth and eighteenth week after gestation, the fetus shows a clear response to pain in multiple studies, and at least one brain pathway is mature enough to create a perception of pain. The fetus also practices breathing, crying, and breastfeeding in the womb. The fetal heart has beat over 20 million times and circulates about 55 quarts of blood per day.

Did You Know ?

In the eighth month of pregnancy the fetal brain is ready to learn! At 32 weeks after conception, neurons are creating 40,000 new connections, called synapses, every second! With repeated exposures, the fetus can learn flavors, nursery rhymes, songs, and even words that she will recognize after birth!

Steve Calvin, M.D.

Associate Scholar

Steve Calvin is board-certified in OB/GYN and Maternal-Fetal Medicine. He has cared for mothers and babies with the entire range of pregnancy concerns. As founder and medical director of the Minnesota Birth Center he strongly supports pregnancy care for low-risk mothers that is provided by nurse midwives in birth centers and hospitals.  

He believes that health care reform should start where we all did – with pregnancy and birth, and that all mothers deserve comprehensive team-based care for a single package price. To that end he developed the BirthBundle® and is focused on improving care for mothers and babies covered by Medicaid.  

He is currently in the last year of an appointed four-year term on the U.S. Department of Health and Human Services (HHS) Advisory Committee on Infant and Maternal Mortality.

Induced Abortion and Risk of Subsequent Preterm Birth

Preterm birth is one of the most significant challenges facing the field of obstetrics and remains a considerable public health issue. For years, concerns have been raised about a potential association between frequently performed induced abortion procedures and preterm delivery in subsequent pregnancies.  Such concerns have been largely ignored in mainstream U.S. medical literature and are unknown to wider public opinion.  However, a growing body of worldwide evidence suggests that the association between preterm birth and history of induced abortion is indeed credible.
