Relaxin
Relaxin
Relaxin (/rɪˈlæksɪn/) is a protein hormone that is involved in a variety of physiological processes, including pregnancy, childbirth, and tissue remodeling.
Etymology
The term "relaxin" is derived from its ability to "relax" the pubic symphysis during childbirth. It was first identified in the early 20th century.
Function
Relaxin is produced in the ovaries, placenta, and prostate gland. During pregnancy, it helps to prepare the body for childbirth by relaxing the ligaments in the pelvis and softening and widening the cervix. It also plays a role in the development of the mammary glands.
In men, relaxin enhances sperm motility and is involved in the development of the prostate gland.
