Surrogacy or surrogate motherhood, mistakenly defined by many as the rental of wombs or “womb-for-rent” service, is a fertility treatment by which a woman other than the intended mother carries the pregnancy to term and gives birth to the baby.

This method involves great complexity from an ethical and emotional perspective, as it breaks with tradition to provide a new understanding of family formation.

Different types of surrogacy

Surrogacy is a fertility procedure that involves a woman who agrees to carry someone else’s baby. This woman is known as surrogate or gestational carrier, while the patients are usually called intended parents.

We can distinguish between two types of surrogacy depending on how the surrogate achieves pregnancy:

  • Traditional, partial, genetic, or straight surrogacy: In this case, the surrogate contributes an egg as well, and therefore her genetic load. In this case, surrogacy is done through intrauterine insemination with the intended father’s sperm, although IVF using the surrogate’s eggs is possible as well.
  • Gestational, host, or full surrogacy: The surrogate or gestational carrier does not contribute an egg for the creation of an embryo. In this case, the genetic material of the baby-to-be is that of the intended mother. Using donor eggs is possible as well.

It should be noted that traditional or genetic surrogacy has almost fallen into disuse nowadays, as it would mean the surrogate developing a greater emotional attachment to the unborn baby. Ideally, the intended mother should be the one contributing the egg; failing that, then egg donation could be used as alternative plan B.

The gestational, host, or full surrogacy option is commonly the only type allowed in the vast majority of countries where this fertility treatment is permitted.

On the other hand, surrogacy can be classified into two more types if we take into account the financial compensation surrogates can get in certain countries. Depending on whether she is economically compensated or not, we can distinguish between:

  • Commercial surrogacy: Surrogates are paid for carrying the pregnancy, apart from being given a compensation in recognition of the expenses derived from the process.
  • Altruistic surrogacy: Surrogates can be financially compensated in recognition of the expenses derived from the pregnancy such as maternity clothes, prenatal visits, special meals required, visits to the hospital, etc.

The total cost of the treatment will depend on the type of surrogacy chosen. For instance, commercial surrogacy, as well as the need for turning to donor eggs and/or sperm, would add to the overall costs of the treatment. In addition, surrogacy fees vary from country to country, depending on each destination’s particularities.

Why surrogacy might become necessary?

The group of patients for which surrogacy is often necessary are heterosexual or straight couples which find themselves in one of the following situations:

Also, single women and lesbian couples suffering from one of the above mentioned issues could become mothers thanks to surrogacy.

Likewise, single men and same-sex male partners often resort to surrogacy to have a baby, as it is the only way for them to have a genetic child using their reproductive cells. In these cases, surrogacy is required just because human males do not have the anatomy needed for natural embryonic and fetal development.

Surrogacy around the world

Surrogacy has always been considered to be a controversial fertility option, which boundaries between what’s ethical and what’s not are still blurred. The reason behind should be understood in legal terms: surrogacy is not allowed everywhere. That is why many patients have no alternative but to cross borders to have the chance to create a family.

On the other hand, it should be borne in mind that even countries which are in favor of surrogacy, this fertility treatment is surrounded by a number of restrictions and particularities that might make it difficult for foreign citizens to make their dream come true.

Some countries like the United States allow all types of surrogacy, whether it is commercial, altruistic, partial, or full surrogacy. Also, all family types can access this fertility treatment: single men or women, same-sex or straight couples. Other countries such as Canada allow every family type to undergo surrogacy, but just the altruistic option.

In Russia, only heterosexual couples can undergo surrogacy, which means gay couples and single individuals do not have the chance to become parents through this method. Spain, France, and Germany are examples of countries in which this fertility treatment is forbidden or not contemplated in national law.

For example, surrogacy is not allowed in Spain because the Law on the Application of Human Assisted Reproduction Techniques explicitly says the legal mother is the woman who gives birth to the baby. Also, every agreement made for the purpose of waving the entitlement of maternity in favor of another woman is legally void.

    There are plenty of reasons why surrogacy has nothing to do with exploitation of women. First, when one talks about “exploitation”, we assume the woman is being forced to do something against her will. I don’t think gestational carriers are forced to carry a baby, but do it because they’ve a strong desire to help others. Second, a pregnancy is a 9 month period in which the surrogate, unfortunately, feels the same pains and discomforts every woman who gets pregnant naturally feels, so she deserved being compensated in some way. Our capitalist world has decided that this compensation is in the form of money… I’m not going to share my opinion, but if that’s how it should be, or the only way a woman who’s been a surrogate can feel rewarded, then I agree in all terms.

      So… you say “plenty of” and then just mention 2? hahaha there’s no way surrogacy can be that perfect, it contravenes many social aspects we humans have been building for a long time… And suddenly we aim to break tradition? it’s not that easy bae

    If the surrogate receives money for the surrogacy the arrangement is considered commercial surrogacy, if she receives no compensation beyond reimbursement of medical and other reasonable expenses it is referred to as altruistic.
