what is the medical term for the relaxin hormone in pregnancy
A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. Relaxin is a vital pregnancy hormone that also can be the source of some decidedly unrelaxing aches and pains. Before I talk about its side effects, you first need to understand the hormone's purpose. Relaxin does just what you'd think it does - it relaxes. Most importantly, it relaxes the intrauterine ligaments.
