Relaxin During Pregnancy

Relaxin is a hormone produced by the ovaries and in the placenta during pregnancy. When this hormone is released in the body,  the sex organs undergo a transformation, so that the process of delivery becomes easier. The muscles of the ligament in the pelvis become relaxed and the cervix is widened.

Relaxin during the first trimester

Relaxin during pregnancy

When corpus luteum is circulated in the ovaries, then a hormone named relaxing is released. During pregnancy, this hormone is circulated from the placenta also. After ovulation, the levels of relaxin rise and hence the walls of the uterus are also relaxed due to inhibiting contractions. These hormones usually pass through the lining of the uterus and a woman becomes pregnant. But, if she does not become pregnant, then the relaxin levels become lower. But, during pregnancy, the relaxin levels rise drastically and they are higher during the first pregnancy and first trimester. At this stage, the fetus in the womb is properly implanted which develops later on.

This hormone also prevents the uterus from contracting and hence it prevents pre-mature birth. The muscles of the renal system and the cardiovascular system become relaxed resulting in increased blood circulation. The blood circulates properly from the cardiovascular system to the placenta and kidneys.

During the third trimester

At the end of the third trimester, the relaxing products rupture the membranes surrounding the fetus. The cervix should be widened during the process of childbirth. The ligaments that are presented in front of the pelvis are relaxed.

This hormone is released in the ovary during the menstrual cycle and it is stimulated by the luteinizing hormone that is released from the pituitary gland. It enters through the lining of the uterus and flows back if the woman is not pregnant. If the woman is pregnant, then it is present in the uterus and the levels of relaxing become higher during pregnancy. It helps is relaxing various muscles in the abdominal area.

Due to excessive levels of production, a woman may experience premature birth. The fetal membranes are ruptured and the cervix is opened earlier. If this hormone is not secreted adequately, then it is known as scleroderma. Due to this condition, the skin hardens and different parts of the body such as the stomach, lungs, and blood vessels are hardened.

In the female, this hormone is produced by corpus Lethem, and during pregnancy by the placenta. Usually, this hormone is produced by both pregnant and non-pregnant females and the levels of relaxing rise during pregnancy. This hormone is involved in the process of decasualization, allowing the endometrial to cause implantation. During the first trimester of the pregnancy, excessive relaxing is produced in deciduas. So, throughout pregnancy, it plays a vital role in relaxing different muscles of the body. The muscles of the cervix and vagina are relaxed before the process of childbirth. So, the process of childbirth becomes easier.

Experts have not been able to research, how this hormone can be controlled. The relaxing hormone can usually feedback to the pituitary or fetus to stimulate human chorionic gonadotrophin levels so that the hormone is controlled.
