In women, relaxin is secreted into the circulation by the corpus luteum in the ovary. During pregnancy it is also released from the placenta, the membranes which surround the fetus, and the lining of the uterus

In men, relaxin is secreted from the prostate gland and can be detected in the semen, but is not generally found in the blood circulation.

The effects of relaxin are most well-described during the female reproductive cycle and pregnancy. Relaxin levels in the circulation rise after ovulation, during the second half of the menstrual cycle. At this stage it is thought to relax the wall of the uterus by inhibiting contractions, and it also prepares the lining of the uterus for pregnancy. If pregnancy does not occur, relaxin levels drop again.

Early in pregnancy, relaxin also inhibits contractions in the wall of the uterus, to prevent premature childbirth. Relaxin can regulate the mother’s cardiovascular and renal systems to help them adapt to the increase in demand for oxygen and nutrients for the fetus, and to process the resulting waste products. It is thought to do this by relaxing the mother’s blood vessels to increase blood flow to the placenta and kidneys.
