The hormone that maintains pregnancy is progesterone

The hormone that maintains pregnancy is progesterone. Progesterone plays a crucial role in preparing and maintaining the uterus for pregnancy. After fertilization, the fertilized egg implants itself into the uterine lining, and the levels of progesterone rise.

Progesterone helps in several ways to ensure the success of the pregnancy. Firstly, it helps to thicken and maintain the uterine lining, known as the endometrium, which provides a nourishing environment for the developing embryo. This thickened lining helps to prevent the shedding of the uterine lining during menstruation, thus maintaining the pregnancy.

Furthermore, progesterone also helps to relax the smooth muscles of the uterus, preventing contractions that could potentially lead to a miscarriage. This muscle relaxation effect of progesterone is important throughout the pregnancy to maintain a stable environment for the growing fetus.

In addition, progesterone plays a vital role in suppressing the mother’s immune response, preventing her body from rejecting the developing fetus as a foreign object. This is important because the fetus carries genetic material from both the mother and the father, which could potentially be recognized as foreign by the mother’s immune system.

Overall, progesterone is a key hormone in maintaining pregnancy by supporting the development of the uterine lining, preventing contractions, and suppressing the immune response to support the growth and development of the fetus.
