+25 Years Making Dreams Come True
Le ceti ® et l’Association Cigogne de l’Espoir ont développé un partenariat stratégique afin de transformer ce rêve en réalité.
CETI'S FOUNDER
Prof. Dr. João Luís Silva Carvalho is a medical doctor specializing in Gynecology/Obstetrics, with a subspecialty in Reproductive Medicine and a PhD from the Faculty of Medicine of Porto, obtained with “Unanimous approval with distinction and congratulations”.
Prof. Dr. Silva Carvalho has been University Professor at the Faculty of Medicine of Porto, President of the Portuguese Society of Reproductive Medicine, member of the European Society of Human Reproduction and Embryology (ESHRE) and has been awarded the international “Grant for Fertility Innovation” prize.
The Professor’s clinical activity is currently carried out exclusively in Portugal, although his clinical training has taken on an international dimension, with courses at Spaarne Hospital (Netherlands), Instituto Dexeus (Barcelona) and laparoscopic surgery internships at the Centre for Reproductive Medicine of the Academisch Ziekenhuis-Vrije Universiteit (Brussels).

Our Clinical Team
Professor João Luís Silva Carvalho’s team is made up of 17 doctors, 10 of whom are gynecologists practicing in the field of fertility and 4 embryologists specialized in PMA. The team is organized in a multidisciplinary and integrated way, so that other clinical members support the study of fertility, such as the urology unit for male factors and the emergency medicine unit for support of fertility procedures.
OUR TREATMENTS
CETI offers technology-supported assisted reproduction treatments, including the use of artificial intelligence techniques to support embryo selection and pre-implantation genetic diagnostic testing (PGT-A, PGT-SR, PGT-M).
Intrauterine Insemination
A painless, uncomplicated assisted reproduction treatment in which carefully processed sperm is placed directly into the woman's uterus.
In Vitro Fertilization (FIV/ICSI)
Medically assisted reproduction technique involving gamete processing and laboratory fertilization (in vitro).
Oocyte Donation
Egg donation is an act of altruism that can help women or couples realize their dream of having a child who would otherwise be unable to do so, due to a lack of eggs in the woman of the couple.
Sperm and Embryo Donation
Sperm donation is the act of using a third party's sperm to fertilize the female gamete (egg). A couple with fertility problems, or a woman without a partner, can realize their dream of becoming parents.
Fertility Cryopreservation
The process of preserving biological material (gametes, zygotes, cleavage-stage embryos, blastocysts, testicular tissue, ovarian tissue) at extremely low temperatures.
Cryopreserved Embryo Transfer
Cryopreserved embryo transfer cycle. It involves thawing the embryos, preparing the patient's endometrium and transferring the embryos into the uterine cavity.
YOUR DREAM IS OUR PASSION

Il y a plus de 25 ans que le CETI est engagé dans la fertilité, c’est pourquoi la concrétisation du partenariat avec l’une des principales associations françaises qui aide les personnes souffrant d’infertilité est quelque chose de pertinent et de grande valeur pour tous ceux qui vivent une situation complexe, mais avec des voies viables et des possibilités optimistes pour atteindre le rêve de la paternité.
L’Association Cigogne de l’Espoir aide tous ceux qui la sollicitent, principalement des citoyens de pays francophones, à travers des informations, en aidant à trouver des solutions, en particulier par les possibilités existantes de dons d’ovocytes (y compris à l’étranger), de dons d’embryons, pour comparer des expériences, des espoirs, des réussites et des échecs, en résumé, pour créer une communauté autour de l’infertilité.
