Gender selection does not biologically alter IVF success rates, as pregnancy odds depend on embryo quality rather than sex. However, the required preimplantation genetic testing (PGT) increases success per transfer by ensuring only chromosomally normal embryos are used, significantly reducing miscarriage risks.
- Genetic screening benefit: PGT identifies healthy embryos, raising implantation success regardless of gender.
- Embryo attrition risk: Prioritizing a specific sex may reduce the available pool of transferable embryos.
- Testing accuracy: Modern biopsy techniques allow for nearly 100% accurate sex identification and screening.
- Selection priority: Choosing lower-quality embryos based on gender can slightly lower overall pregnancy chances.
Bookimed Expert Insight: Success in Spain often depends more on lab precision than the selection itself. Clinics like Centro Médico Teknon utilize JCI-accredited labs where surgeons like Dr. Cayetana Barbed oversee complex PGT protocols. Data shows that while gender selection is popular for family balancing, the highest success rates occur when patients allow specialists to prioritize the highest-graded embryo from the tested pool.
Patient Consensus: Patients often reflect that while choosing a gender provides peace of mind, the emotional reality revolves around the number of healthy embryos available. Many suggest focusing on lab quality and transfer strategy rather than viewing gender as a factor that changes biological outcomes.
