When a person or couple encounters an insurmountable obstacle on their path to parenthood, it's normal for them to begin exploring all possible avenues. Among the options offered by modern science, surrogacy has become a highly sought-after alternative, although it remains a controversial topic that sparks heated debates at family dinners and legal forums alike.
Basically, we're talking about an agreement where a woman agrees to carry a baby in her womb, and once born, the baby will be given to the intended parents. This process, which sounds simple on paper, involves tremendous medical and legal complexity , as it depends entirely on your geographical location and the type of contract signed.
Types of surrogacy: How does each one work?
To begin exploring this topic, it's important to distinguish between two very different approaches based on genetics. On the one hand, we have traditional surrogacy , which is the oldest method. Here, the woman carrying the baby is also its biological mother because her own egg is used. Depending on the case, fertilization can be natural or through techniques such as intrauterine insemination or IVF.
On the other hand, there is gestational surrogacy , a much more modern technique where the surrogate mother has no biological connection to the child. In this scenario, an embryo created in a laboratory is transferred to the uterus. This allows the intended parents to have a direct genetic connection with the child, even though the woman only acts as a temporary surrogate.
Within this gestational world, there are several routes depending on the genetic material used:
- When using the eggs and sperm of the couple, maintaining the total biological link.
- When resorting to a egg donor But the father is biological, ideal for single women or homosexual couples.
- When it's used donor sperm and the mother's eggs.
- In cases of total sterility, where it is used genetic material from third parties both for the egg and for the sperm.
Financial compensation: Altruism versus commercialization
It's not all about biology; money plays a crucial role in how this process is classified. Commercial surrogacy occurs when the woman receives financial compensation agreed upon and notarized through an agency. It's the most common model in countries where it's legal, although many critics believe it turns the human body into a profitable commodity.
On the other hand, we find altruistic surrogacy . Here, it's usually a friend or family member who decides to help without charging a single euro for their service. However, just because it's free doesn't mean there are no costs; the intended parents must cover all medical expenses , legal fees, maternity clothes, and any unforeseen events related to the pregnancy.
In addition, there are so-called independent processes . This occurs when the intended parents find a surrogate on their own, bypassing agencies. While they save on commissions, they expose themselves to scams and considerable legal risks due to the lack of professional support to coordinate all the paperwork.
The complex legal landscape in Spain
In Spain, the situation changes dramatically. Since 1988, the law has been unequivocal: any surrogacy contract is null and void . Whether motivated by compassion or financial gain, in Spain the law recognizes the woman who gives birth as the mother, making these practices very serious offenses.
This prohibition is not arbitrary, but rather based on ethical and social grounds . It seeks to prevent the exploitation of vulnerable women and the objectification of newborns. Furthermore, there is significant legal uncertainty regarding the registration of children in the Civil Registry, as the Supreme Court and the Directorate General of Registries have not always acted in the same direction.
Recently, the rules have become stricter. Now, registering a baby born through surrogacy abroad is no longer automatic. To prevent Spaniards from circumventing national law by traveling to other countries, the Civil Registry now requires that parentage be strictly determined by biological link or adoption , following the most recent jurisprudence that denies recognition of foreign judgments validating contracts that are null and void in Spain.
International perspective and diversity
Beyond our borders, the map is a mosaic. While Germany, France, and Italy follow Spain's lead in prohibiting surrogacy, other countries are more flexible. The United Kingdom, for example, allows surrogacy for therapeutic reasons but prohibits profit-making. Portugal, for its part, has legislated to be more permissive, allowing access to foreigners as long as it takes place in Portuguese clinics, although it remains restricted to medical cases and excludes same-sex couples.
It's important to mention that this path is frequently taken by single men . Although medically it's a simple process (father's sperm and donor egg), the legal aspect is a real labyrinth. Many specialized agencies help these prospective fathers find secure legal solutions so they can exercise their parental rights without fear of legal repercussions.
To this day, surrogacy remains one of the most divisive issues in bioethics. While some see it as a technological blessing for families unable to conceive, others condemn it as a violation of human dignity. In Spain, the current trend is to tighten legal restrictions to protect the best interests of the child and prevent motherhood from becoming a contractual service.
