Genetic connections of a child in a surrogacy program


Surrogacy, an extraordinary assisted reproductive technology, offers a beacon of hope for parents grappling with partial infertility. This intricate process enables at least one parent to contribute genetic material, paving the way for the birth of their biological child. Despite its benefits, surrogacy is shrouded in myths and misinformation, particularly concerning the genetic relationship between the child and the surrogate mother or gestational carrier.

The Genetic Bond: Child and Surrogate Mother

A common question that stirs curiosity among prospective parents considering gestational surrogacy is whether the child will carry the surrogate mother's genes. To understand this, we need to delve into the basics of genetic transfer during physiological fertilization.

The creation of a new life requires two sex cells: a sperm and an egg. Each carries 50% of the genetic code of the future child. During fertilization, these cells unite, forming a new cell that contains 50% of the mother's DNA and 50% of the father's DNA. This genetic information, which includes traits, behaviors, and even predispositions to certain diseases, is passed down from the parents to the child.

In surrogacy, the biological parents' cells are used, if possible. The mother's egg is retrieved, and the father's sperm is collected. These cells are then combined in a laboratory setting, where an embryo develops over several days. This embryo, already carrying its complete genetic code, is then implanted into the surrogate mother's uterus. The surrogate mother carries and gives birth to the child.

Given this process, it's clear that no genetic information from the surrogate mother can be added to the existing one. The surrogate mother's role is to provide the necessary nutrients and microelements for the child's full development.

The Surrogate Mother's Influence During Gestation

Despite the clear genetic boundaries, surrogate mothers can influence the child's development and overall health. A blood-placental barrier exists between the surrogate mother and the baby, protecting the baby from harmful substances. However, this barrier cannot filter out all harmful substances, such as:

  • Tobacco particles
  • Heavy metals
  • Drugs
  • Certain chemicals

These elements can trigger malformations or activate a genetic disease inherent in the parents' genes. This underscores the importance of selecting a surrogate mother with utmost care. The surrogate mother's lifestyle during pregnancy can significantly impact the child's health.

Surrogate mothers are therefore selected with utmost care in surrogacy agencies. They undergo comprehensive examinations and lifestyle monitoring to ensure a healthy pregnancy. This vigilance helps mitigate the risks associated with harmful substances and infectious diseases.

Emotional Attachment: Surrogate Mother and Child

Carrying a child for nine months naturally creates a bond between the surrogate mother and the baby. However, this bond is more about concern for the child's health and well-being rather than a genetic connection. Studies show that 85-90% of surrogate mothers do not experience psychological difficulties when handing over the child to the biological parents. This is largely due to the understanding that the child they are carrying is not biologically theirs and the support they receive from psychologists and training programs.

Whose features will the baby inherit after being born through surrogacy?

The child's physical traits are determined by the genes of the biological parents. A surrogate mother cannot physiologically transfer any part of her genome to the child. Therefore, any resemblance between the child and the surrogate mother would only be coincidental, based on similarities between her and the biological parents.

The Need for a DNA Test Post-Birth

In many jurisdictions, DNA analysis of the child and biological parents is mandatory at the end of surrogacy programs. This is done to reassure parents that the child is genetically identical to them and for legal documentation. Numerous studies have confirmed that a child is always genetically identical to their parents, with no resemblance to the gestational carrier.

Key Takeaways

To summarize, here are the key points about the genetic relationship of a child in a surrogacy program:

  • The child's genetic material comes solely from the biological parents, not the surrogate mother.
  • The surrogate mother's role is to provide a nurturing environment for the child's development, not to contribute genetic material.
  • The surrogate mother's lifestyle during pregnancy can influence the child's health, but not their genetic makeup.
  • Emotional attachment between the surrogate mother and the child does not imply a genetic connection.
  • DNA tests confirm the genetic relationship between the child and the biological parents.

These insights dispel common misconceptions about gestational surrogacy and provide a clearer understanding of the process. With this knowledge, prospective parents can make informed decisions about surrogacy.

Wrapping Up

Surrogacy is a remarkable process that opens up the possibilities of parenthood to those who may otherwise struggle. It's a journey filled with challenges, but the reward at the end is priceless: the gift of a child who is genetically your own. As we continue to debunk myths and spread accurate information about surrogacy, we can help more people explore this extraordinary path to parenthood.

Under Ukrainian law, surrogacy is a legal affordable option for traditionally married couples to have children using their own embryos, or with either an egg or sperm donor. There must be a medical reason you can’t carry a child. You are also able to participate if you have had 4 unsuccessful IVF attempts.
