In the months preceding birth, the hormone which causes pelvic ligaments to become more flexible to enable widening of the pelvis during delivery is relaxin.
What is relaxin hormone?
- The ovary and placenta both generate the hormone relaxin, which has significant effects on the female reproductive system and on pregnancy.
- It loosens the ligaments in the pelvis and softens and opens the cervix in order to prepare for childbirth.
- Progesterone starts to come out of the corpus luteum, and it combines with relaxin to thicken the uterine lining, aiding in the implantation of the fertilized egg.
- In both pregnant and nonpregnant females, the corpus luteum is principally responsible for producing relaxin.
- During pregnancy, its plasma levels are at their peak.
- The decidua and placenta both manufacture relaxin during this state.
- Relaxin is produced in the prostate and released into the seminal fluid in males.
