When conceiving naturally, hormone levels undergo changes, with varying effects from person to person. However, achieving a successful pregnancy without these essential hormones is challenging.

Initially, a surrogate mother’s body does not naturally produce pregnancy hormones. Therefore, physicians utilize medications to stimulate their release and maintain appropriate levels in the body. Fortunately, hormone therapies for surrogates are highly effective and boast a high success rate. Here’s more information to reassure you about pregnancy hormones and surrogacy.

Why are hormone treatments essential for surrogates?

During a natural pregnancy, specific hormones are produced by the body to prepare for the upcoming journey. These hormones are crucial for a successful and healthy pregnancy as they facilitate the development and growth of the embryo.

For surrogate pregnancies, hormone treatments can mimic the effects of the natural hormones present at the time of conception.

Which hormones are vital during a surrogate pregnancy?

The critical pregnancy hormones include:
• hCG
• Estrogen
• Progesterone
• Estrone (E1)
• Estradiol (E2)
• Estriol (E3)
• Prolactin
• Relaxin

Human chorionic gonadotropin, or “hCG,” is one of the earliest hormones released when you conceive. It plays a significant role in preparing the ovaries during the first trimester, and home pregnancy tests detect this hormone in urine. Thus, hCG serves as a “trigger” hormone, signaling the body to release more estrogen and progesterone by forming the corpus luteum.Estrogen aligns with a woman’s menstrual cycle. Its levels remain elevated during pregnancy, peaking a few weeks before childbirth. Notably, there are three types of estrogen: E1, E2, and E3.

E1 is a weaker form produced post-menopause, while E2 is the primary estrogen in adults. E3 is closely related to pregnancy as it’s responsible for building a healthy womb lining.
Progesterone assists the womb in supporting a healthy embryo and prevents womb contractions and premature labor. Physicians may recommend additional progesterone during the first few weeks.
Prolactin initiates breast milk production, while relaxin stops the womb from contracting and induces relaxation during labor for a smoother birth.

What are the benefits of using pregnancy hormones?

The primary benefit of using pregnancy hormones is their effectiveness. Administering pregnancy hormones is time-efficient and safe, especially for individuals in excellent health. A smooth pregnancy is more likely when your body is adequately prepared with the appropriate hormone levels to support a healthy baby.
