Pregnancy Hormones and Surrogacy

Pregnancy is a transformative and remarkable journey that involves a multitude of physical and emotional changes for the expectant mother. These changes are primarily driven by the complex interplay of hormones. One crucial aspect of surrogacy is the intricate relationship between pregnancy hormones and the successful outcome of the surrogacy journey. In this informative blog post, we will delve into the significance of pregnancy hormones in surrogacy, exploring their role in supporting a healthy pregnancy and the well-being of the surrogate mother.




The Role of Pregnancy Hormones


During pregnancy, hormones play a vital role in creating an optimal environment for fetal development. Let's explore the key hormones involved and their functions:


a) Human Chorionic Gonadotropin (HCG): Produced by the placenta, HCG is the hormone responsible for confirming pregnancy through a positive pregnancy test. It supports the production of other essential hormones, such as estrogen and progesterone, which are crucial for sustaining the pregnancy.


b) Estrogen: Estrogen levels surge during pregnancy and contribute to various changes in the expectant mother's body. It aids in the growth and development of the fetus, supports healthy blood flow, promotes the growth of breast tissue, and prepares the body for childbirth.


c) Progesterone: Progesterone plays a crucial role in maintaining the pregnancy by supporting the development of the uterine lining and preventing contractions. It also helps suppress the mother's immune response to prevent rejection of the embryo.


d) Relaxin: This hormone helps relax the ligaments in the pelvis, facilitating an easier passage for the baby during labor and delivery. It also helps prevent premature contractions.


Hormonal Dynamics in Surrogacy


In the context of surrogacy, although the surrogate mother is not genetically related to the child she carries, her body undergoes similar hormonal changes to support a healthy pregnancy. Here's how pregnancy hormones are managed in surrogacy:


a) Hormonal Preparation: Before embryo transfer, the surrogate may undergo hormonal therapy to synchronize her menstrual cycle with the intended mother's or the egg donor's cycle. This synchronization ensures the uterine lining is receptive for successful embryo implantation.


b) Hormone Replacement Therapy (HRT): In some cases, surrogates may receive estrogen and progesterone supplementation to prepare the uterus for implantation and support early pregnancy until the placenta takes over hormone production. HRT helps establish an ideal hormonal environment for the embryo's development.


c) Ongoing Hormonal Monitoring: Throughout the pregnancy, the surrogate mother's hormone levels are closely monitored to ensure they remain within the appropriate range for a healthy pregnancy. This monitoring allows healthcare professionals to make any necessary adjustments to hormone dosages, ensuring optimal conditions for the baby's growth and development.


Pregnancy hormones are integral to the surrogacy process, playing a pivotal role in creating an environment conducive to successful embryo implantation, fetal growth, and the overall well-being of the surrogate mother. Through hormonal preparation, hormone replacement therapy, and diligent monitoring, at Patriot Conceptions we ensure that the surrogate's body is adequately prepared to support the development of the intended parents' baby.


The understanding and management of pregnancy hormones in the context of surrogacy have greatly contributed to the success and safety of this remarkable journey. With continued advancements in reproductive medicine, surrogacy continues to evolve, empowering those who long for a child to fulfill their dreams of parenthood.
