Couples planning a pregnancy or seeking help from assisted reproductive technology clinics often ask the same important question: are hearing impairments hereditary, and is there a risk that the child will inherit their parents’ problems? For specialists at the NatuVitro reproductive medicine center (Travessera de les Corts, 322, 08029 Barcelona, Spain), this topic is part of a comprehensive approach to assessing family health. Here, genetic aspects are combined with modern technologies, including IVF with PGD, IVF with donor eggs, as well as individualized infertility treatment programs in Spain. This approach allows not only to diagnose possible genetic factors, but also to minimize the risks of transmitting serious disorders to future children.
Genetic characteristics of hearing disorders: what is important to know
Hearing disorders can be congenital or acquired, but heredity plays a significant role. According to international studies, up to 50% of cases of congenital hearing loss are due to genetic factors. They can be transmitted in various ways:
- autosomal recessive — the most common type, when both parents are carriers of the mutation;
- autosomal dominant — one parent has a manifest form or is a carrier of the mutation;
- X-linked — typically transmitted through the female line with a more pronounced manifestation in boys;
- mitochondrial — inheritance only through the maternal line.
Even if parents do not have clinically significant hearing loss, they may be hidden carriers of certain DNA changes. Such mutations may not manifest themselves during the parents’ lifetime, but they can be passed on to the child and affect the development of the auditory system.
It should be noted that many forms of hereditary hearing loss are not associated with impaired overall development of the child, but require early diagnosis, monitoring, and, if necessary, the use of hearing aids or other support methods. Therefore, early detection of risks allows prospective parents to make more informed decisions.
PGT as a tool for managing hereditary risks
Modern advances in reproductive medicine allow the condition of embryos to be assessed at the earliest stages of development. One of the key methods is PGT — preimplantation genetic testing, available as part of the IVF Extracorporeal fertilization with PGT program.
This method makes it possible to:
- detect chromosomal abnormalities;
- identify specific genetic mutations, including those associated with hearing impairments;
- select embryos with the optimal genetic profile;
- significantly increase the likelihood of having a healthy child;
- reduce the risk of passing on hereditary diseases.
PGT is a particularly important tool for couples who:
- have a family history of congenital hearing loss;
- have been identified as carriers of genetic mutations;
- have had previous pregnancies in which the child was diagnosed with hearing impairment or treatment failed repeatedly.
Thanks to the accuracy and informative nature of PGT, couples are able to make decisions based on objective data, reducing the degree of uncertainty.
The role of donor eggs in cases of high genetic risk
In some cases, the likelihood of passing on hereditary disorders is so high that a specialist may recommend IVF with donor eggs. This program is indicated if:
- the expectant mother has genetic mutations that affect the functioning of the auditory system;
- her own oocytes have low potential or contain a significant number of defects;
- age-related factors impair the quality of the eggs.
The use of donor eggs significantly reduces the likelihood of transmitting genetic diseases. Donors in Spain undergo rigorous medical, psychological, and genetic screening, which makes such programs safe and effective.
Spain is one of the world leaders in the field of donation thanks to its transparent rules, wide selection of donors, and high standards of medical ethics. Barcelona has long been a center of international medical tourism for patients seeking quality care in the field of reproductive medicine.
Infertility treatment in Spain: a comprehensive approach and advantages
For foreign patients, seeking infertility treatment in Spain, particularly at the NatuVitro clinic, has a number of significant advantages:
- modern laboratory facilities that allow for accurate diagnosis;
- highly qualified doctors specializing in complex reproductive cases;
- the possibility of using PGT, which is unavailable or limited in a number of other countries;
- extensive donor programs that ensure a high level of compatibility;
- a legal framework focused on supporting patients, including single women and same-sex couples;
- accessibility of treatment for patients from abroad without the restrictions typical of many other healthcare systems.
The NatuVitro clinic accompanies the patient at every stage — from the initial consultation and analysis of genetic factors to the selection of the optimal treatment protocol and support during pregnancy. Specialists pay special attention to hereditary diseases, including hearing impairments, which allows for the most informed pregnancy planning possible.
Why the combination of genetics and IVF is the key to confidence for future parents
Modern technologies in the field of reproductive medicine not only make it possible to overcome infertility, but also reduce the risks of hereditary diseases. IVF with PGT programs provide an opportunity to form a clear understanding of the genetic health of the future child, and the use of donor eggs makes it possible to completely exclude the transmission of some hereditary pathologies.
Together, these solutions make Spain — and Barcelona in particular — one of the most attractive destinations in the world for patients seeking safe parenthood.
Conclusion
Hearing problems can indeed be hereditary, but thanks to the achievements of modern science, their impact can be significantly reduced. The NatuVitro clinic takes a comprehensive approach that combines genetic diagnosis, IVF with PGD, the option of using donor eggs, and personalized infertility treatment programs in Spain.
The clinic’s team of specialists is ready to support every family on their journey to having a healthy baby, helping them make decisions based on modern scientific data and creating the conditions for the safest and most successful parenthood possible.
