Hormones of Pregnancy Series: Flexible Effects of Relaxin

During pregnancy a special type of hormone produced by the placenta, known as relaxin, is released in abundance. The hormone, quite fittingly, causes muscles to relax and stretch. This stretching is necessary to help the body accommodate an ever-growing uterus as it stretches from around the size of a tennis ball, to something large enough to support a seven pound baby or two. This hormone also helps to expand the blood vessels without raising blood pressure, help the ligaments to stretch, and all around loosen up a pregnant woman’s body.

Often women notice that crampiness and discomfort around their pelvis region early in pregnancy. This is often a result of relaxin, as it works to help the round ligaments expand.

Though relaxin, which was first recognized in 1926, is primarily associated with pregnant women, it is present in the body of both non-pregnant females, as well as males.

Relaxin keeps the hips flexible and easy to mold post-pregnancy. Peak times for relaxin release are ovulation in the non-pregnant female, first trimester in the pregnant female, and during labor. Following birth the hormone will still be highly concentrated within the body for a bit. This flexible time is a good time to try Hipslimmer, while the hips are still so very malleable.
