Institut Marques is a fertility clinic established in Barcelona in 2003, operating with approximately 80 staff across clinical, laboratory, and administrative functions. The clinic specialises exclusively in assisted reproductive technology, with IVF, egg donation, and pre-implantation genetic testing as its principal services. It holds ISO 9001:2015 certification and is registered with the Spanish Fertility Society (SEF), to whose national outcome registry the clinic reports cycle-level data.
Spain has one of the most active egg donation markets in Europe, operating within a well-regulated legal framework, and Institut Marques is a recognised participant in that market. The clinic's international department serves patients from across continental Europe, the United Kingdom, the Middle East, and Latin America, many of whom travel to Barcelona specifically for donor egg IVF, where Spanish law permits anonymous donation with a large donor pool.
Published pricing covers the main treatment components, including IVF with own eggs, donor egg cycles, and embryo cryopreservation. The clinic's international coordinators provide treatment planning support in multiple languages, and remote pre-consultation by video is available before patients travel.
The embryology laboratory employs vitrification for cryopreservation, time-lapse incubation monitoring, and pre-implantation genetic testing through biopsy and external genetic analysis. The clinic's Barcelona location, served by El Prat International Airport with direct routes from across Europe and beyond, makes it logistically accessible for patients undertaking treatment over multiple visits.
