What Is Surrogacy?

Many women offer to provide surrogacy for intended parents that are unable to carry a pregnancy themselves, it is a legal and medical arrangement.

Gestational surrogacy tends to be the popular option in surrogacy, whilst there is traditional surrogacy available in the world, it isn’t the usual choice. Gestational surrogacy is when the baby will have no genetic link to the surrogate mother. The eggs and sperm of the intended parents or donors create an embryo via IVF (in vitro fertilisation) and is transferred to the surrogate mother.

Before the start of the process, the surrogate has to go through medical screening such as the following;

• Blood tests.
• Hormone level tests.
• Reproductive health assessments, and
• Infectious disease checks.

One key part of this testing is determining the Rhesus (Rh) factor in the surrogate’s blood, a small but important detail that can affect the outcome of the pregnancy. It’s important to be conscious of the complicated medical decisions in surrogacy, especially when factors like Rh incompatibility are involved. When you understand the Rh factor in the process it helps everyone make safe and informed choices.

Surrogacy with a Negative Rh Factor – Is It Possible or Not?

The opportunity for intended parents to have a baby and expand their family through a surrogate mother is a special chance to experience the happiness that is brought into your life with parenthood when other options haven’t been successful. It’s a very emotional and life changing experience. It is also a medically supported way to build a family for intended parents who cannot conceive naturally.

Surrogacy is a medical process, and one important medical detail in surrogacy is the Rh factor, a protein found in blood. Many women ask: Can you do surrogacy with a negative Rh factor? And why do most surrogacy agencies ask for a surrogate with a positive Rh factor?

These questions are commonly asked because many potential surrogates or curious intended parents have heard that Rh-negative women are often rejected for surrogacy. It’s understandable that people want to know why, and if there have ever been any special cases.

People tend to ask these types of questions because they want to know if it’s a strict rule or a guideline. Some women with negative Rh blood want to help others and feel confused when they’re turned down. In other instances, Intended parents may want to work with a specific surrogate who happens to be Rh-negative, this could be a friend or relative.

There’s also not a lot of clear public information explaining why Rh compatibility is important in surrogacy. People want to know if it’s about safety, legal rules, or just agency or clinic preference.

Since Rh incompatibility is a medical issue, it makes sense that not everyone is aware of it. Some surrogates may feel excluded and want to understand if it’s due to unfair treatment or if it is genuinely a high risk. Intended parents can also be concerned about this detail and whether it can affect their choice in a surrogate. It is normal to have these questions and need the answers.

Who Can Become a Surrogate Mother?

Women offering to be a surrogate mother is a magnificent gesture, but it does come with multiple medical responsibilities. This is why surrogacy agencies and fertility clinics have strict eligibility criteria for a surrogate mother as it ensures the safety of everyone involved.

Many agencies have certain requirements relating to the health and lifestyle conditions for surrogate mothers. The main requirements tend to be a surrogate mother should be between the ages of 21 and 40, have had at least one healthy pregnancy and delivery, good physical and mental health, a body weight that falls within a healthy BMI (differs between clinics), no smoking, no history or current use of illegal drugs, a stable and supportive environment, prepared to go through evaluations (medical, psychological and background checks).

Another medical requirement is to have a positive Rh factor in the blood. This detail may seem small, but it does play a huge role in the health of the pregnancy. If a woman has a negative Rh factor are not accepted as surrogates, particularly if the embryo was created using sperm or eggs from Rh-positive biological parents.

It really isn’t about excluding people, it’s a medical precaution that needs to be paid attention to. The reason for this is that if a Rh-negative surrogate carries a Rh-positive baby, it can lead to incompatibility. The condition can cause the immune system to attack the baby’s red blood cells, increase the risk of a miscarriage, delivery complications, fertility and further pregnancy issues for the surrogate or long term health issues for the baby.

Because of the above risks, most surrogacy programmes choose to only work with women who have a positive Rh factor to ensure a reduction in any possible chances of medical complications.

Why Is a Positive Rh Factor Important in a Surrogate Mother?

Most people have Rh in their blood, they are either Rh-positive or Rh-negative. Problems can happen when the surrogate is Rh-negative, and the baby is Rh-positive (because of the egg and sperm used).

As previously mentioned, if a surrogate has Rh-negative blood and the baby has Rh-positive blood, this is called Rh incompatibility. In this instance, the surrogate’s body may act badly towards the baby as the body is seeing it as “foreign” causing it to try to attack like it would fight off an infection. This can cause serious problems like haemolytic disease of the newborn (HDN), it can cause other medical issues such as the following;

• Anaemia (low red blood cells in the baby).
• Jaundice.
• Damage to the baby’s organs.
• Miscarriage or stillbirth in severe cases.

Rh factor issues can still happen during a first pregnancy, especially if there is bleeding, a miscarriage, or other medical procedures.  If the surrogate’s body makes antibodies, it could affect her future pregnancies.

This is why most clinics prefer to work with women who have a positive Rh factor.

Frequently Asked Questions

What does “Rh factor” mean?

Rh factor is a type of protein found on red blood cells. If you have it, you’re Rh-positive. If you don’t, you’re Rh-negative. It’s a normal part of your blood type.

How do I know if I’m Rh-negative or Rh-positive?

A simple blood test at your doctor’s office or clinic can tell you your Rh type.

Can a woman with a negative Rh factor be a surrogate?

Yes, but only in rare cases. Most agencies require a positive Rh factor to reduce health risks.

Why do agencies check the Rh factor?

To avoid Rh incompatibility, which can cause health problems for both the surrogate and the baby.

What if the intended parents also have negative Rh?

If both the surrogate and the parents have negative Rh, surrogacy might be possible. But it depends on the clinic’s rules and medical checks.

Is surrogacy with a negative Rh factor ever safe?

It can be safe, but only with special medical care and correct Rh matching.

Can Rh problems be prevented?

Sometimes, yes. Doctors can give a special injection (RhIg) to help prevent the surrogate’s body from reacting. But it doesn’t always work in surrogacy cases.

Why is the Rh factor more important in surrogacy than in normal pregnancy?

The baby’s blood type usually comes from the intended parents in surrogacy. If it doesn’t match the surrogate’s Rh type, it can cause health problems. That’s why clinics take extra precautions.

Is there any way to still help others if I can’t be a surrogate?

Yes! You could explore egg donation, which is a different but equally valuable way to help people start a family. Rh factor doesn’t matter for egg donation.

Will being Rh-negative affect my own pregnancies?

It might, especially if your body develops antibodies. But with proper medical care and monitoring, many Rh-negative women have healthy pregnancies.
