The journey of surrogacy is a path filled with hope, determination, and sometimes, complexity. A crucial aspect that influences the success of a surrogacy process is the age of everyone involved: the surrogate mothers, the intended parents, and the egg donors. Age affects various factors including fertility, pregnancy health, and the surrogacy outcome.

Let’s explore how age and having a history of previous successful pregnancy and delivery play a pivotal role in becoming a surrogate.

The Importance of Age for Surrogate Mothers

Surrogate mothers are indispensable in the process of gestational surrogacy, offering their wombs to carry the pregnancies to term. The preferred age for gestational carriers is broadly set between 21 and 39 years for several compelling reasons:

  1. Previous Successful Pregnancy and Delivery: Women within this age bracket are more likely to have experienced at least one previous successful pregnancy and delivery without significant issues, a fundamental criterion for surrogacy agencies. This history suggests they can carry a pregnancy to term with a lower risk of complications, making them ideal candidates for surrogacy. 
  2. Reduced Pregnancy Complications: Younger surrogates typically present with a lower incidence of health risks such as gestational diabetes and high blood pressure, conditions that can complicate pregnancy. Their lower risk profile is associated with higher chances of maintaining a healthy pregnancy and achieving a successful delivery, often resulting in vaginal deliveries without the need for interventions like induction of labor or blood transfusion. 
  3. Healthy Pregnancy Outcome: The chances of miscarriage, chromosomal abnormalities, and birth defects are statistically lower in younger surrogate mothers. This is partly due to better overall health, including factors like a healthy weight and a more robust response to fertility treatments if needed. Consequently, these surrogates are more likely to contribute to healthier pregnancy outcomes, with fewer birth defects and higher birth weights, leading to successful pregnancies. 

The Role of Age in Egg Donation

If you plan on becoming an egg donor, age is also a strict requirement. The age of the egg donor is pivotal, especially in scenarios where the intended mother is unable to use her eggs. Typically, egg donors are selected from women aged between 21 and 29 due to:

  1. Egg Quality and Quantity: Women in this age group tend to produce a higher number of eggs during each menstrual cycle, with a lower likelihood of genetic mutations. This leads to the creation of high-quality, healthy embryos, which are crucial for a successful embryo transfer and, ultimately, a successful pregnancy. 
  2. Lower Risk Factors: Eggs from younger donors come with a reduced risk of complications like preterm birth, low birth weight, and neural tube defects. These eggs offer the best chance for a healthy embryo, minimizing the risk of miscarriage and genetic conditions that could affect the fetus.

How Age Affects Intended Parents

The age of intended parents, particularly that of the intended mother (if using her eggs), significantly influences surrogacy success rates due to:

  1. Menstrual Cycle and Fertility: Older intended mothers may experience issues with their menstrual cycle and a decline in fertility, often leading to the necessity for donor eggs to achieve a successful pregnancy. This is where reproductive technology and fertility treatments play a crucial role. 
  2. Reproductive Technology Success: The success rates of advanced reproductive technologies such as IVF (In Vitro Fertilization) and artificial insemination can vary based on the age of the genetic material used. While younger eggs increase the chances of a successful pregnancy, older eggs may lead to increased risk factors, including chromosomal abnormalities and other health conditions that affect the surrogate pregnancy.

The influence of age on surrogacy extends beyond just the medical aspects, touching on the psychological well-being of all parties involved, including the development of mother-child relationships and parent-child relationships post-birth, as studied by researchers like Golombok et al.

Age Requirement For Prospective Surrogates

The minimum age for a surrogate is usually set at 21 years. Setting strict age and health requirement for surrogates ensures that they have reached an adequate level of physical maturity and is legally considered an adult, capable of making informed decisions about her health and the surrogacy agreement. It also increases the likelihood that she has had the opportunity to experience a full-term pregnancy and childbirth, which is a common prerequisite for becoming a surrogate.

On the other hand, the maximum age for surrogate mothers is generally set between 39 and 45 years, depending on the policies of the surrogacy agency or fertility clinic. This range is considered because, beyond this age, the risks associated with pregnancy increase, including a higher likelihood of gestational diabetes, high blood pressure, and other complications that could affect both the surrogate and the baby’s health.

Furthermore, pregnancy rates from assisted reproductive technologies (ART), including IVF, tend to decrease as a woman ages, especially after 40.

Factors Influencing Age Requirements

  1. Health and Medical History: Besides age, surrogacy agencies also consider the overall health and previous pregnancy history of the prospective surrogate. A history of healthy pregnancies and deliveries without complications is crucial. 
  2. Psychological Maturity: Emotional and psychological readiness plays a significant role in the surrogacy process. The minimum age requirement helps ensure that the surrogate is psychologically mature enough to understand and cope with the emotional complexities of surrogacy. 
  3. Legal and Ethical Considerations: Age requirements also reflect legal and ethical considerations, aiming to protect all parties involved in the surrogacy process, including the surrogate, the intended parents, and the child. 
  4. Agency and Clinic Guidelines: Specific age requirements can vary between different surrogacy agencies and fertility clinics. These organizations may have their criteria based on their experience, success rates, and the guidance of medical professionals.
