The use of donated eggs is growing in Brazil and new technologies increase the chances of pregnancy in women who have difficulty getting pregnant
Egg donation is one of the fastest growing assisted reproduction techniques in the world. According to data from the Brazilian Society of Assisted Reproduction (SBRA), more than 12% of babies born through invitro fertilization in the country result from treatments with donated eggs — a number that grows every year. The advancement of technologies, greater social acceptance of the topic and the structuring of donor banks make egg reception an increasingly safe, effective and accessible alternative for women who face difficulties getting pregnant using their own eggs.
The procedure is indicated for patients in menopause, with repeated treatment failures to get pregnant, over 42 years of age or hereditary diseases that prevent the use of their own eggs. It is also an option for male same-sex couples and for women who have decided to postpone motherhood. The combination of technology and empathy — science and solidarity — makes egg donation one of the most transformative practices in reproductive medicine today.
Egg donation is a confidential procedure, carefully regulated by the Federal Council of Medicine. Donors undergo rigorous selection criteria, including medical, genetic, blood tests and psychological monitoring. After controlled stimulation, the eggs are collected and
fertilized with their partner’s or donor’s sperm. The resulting embryos are transferred to the recipient’s uterus, prepared with hormones to receive the embryo.
The entire process takes place anonymously — the identity of the donor and the recipient is preserved. Compatibility criteria take into account physical characteristics, seeking the greatest possible similarity. The average success rate of IVF with donated eggs is 50 to 60% per cycle, double the rates obtained with own eggs in women over 40 years of age. This result occurs because using eggs from young women increases the chance of healthy embryos.
In recent years, new laboratory techniques and the use of artificial intelligence have expanded the possibilities for those who use ovoreception. Automated systems help specialists choose the embryos with the greatest potential for implantation, analyzing development in real time. In addition
In addition, epigenetics — the science that studies how the environment and lifestyle habits influence the expression of genes — has brought a new perspective to the donor and the recipient: even though the embryo’s DNA comes from the donor, the organism and lifestyle of the woman who receives actively participate in the expression of genes.
baby’s genes.
This discovery has a great emotional and scientific impact, showing that the bond between mother and child goes beyond genetic makeup. Studies indicate that proteins, hormones and substances produced by the mother’s body during pregnancy directly influence the baby’s development, creating a connection
unique biological.
With technological advances, egg donation is no longer seen as a last alternative and is now recognized as a real possibility of having a child safely and with love. In a country where motherhood has been postponed and the challenges of getting pregnant increase over the years, ovoreception represents more than a treatment: it is a bridge between science and dreams, hope and reality.
