As women age, their fertility gradually declines—this is a biological fact most people are aware of. After age 35, ovarian function weakens, egg quality decreases, and the chances of conception reduce, while the risk of miscarriage increases. For many older couples, getting pregnant becomes more challenging. However, advancements in medicine have brought hope to those families who still dream of having their own children. Through egg donation and surrogacy, even parents-to-be of an older age have the opportunity to legally have their own children.
Ms. Chen, now in her 40s, and her husband Mr. Zhang have always led a fulfilling life, with successful careers and a happy family. However, as they grew older, they began to realize that one thing was missing—a child. For years, they had been busy with work and life, and only in their forties did they seriously begin considering having children. However, the fertility difficulties that come with age posed significant obstacles when they tried to conceive naturally.
Although both Ms. Chen and Mr. Zhang were still healthy, doctors informed them that aging naturally leads to a decline in ovarian function, and both the quantity and quality of Ms. Chen's eggs had diminished. This reality left them feeling discouraged but also made them consider other possibilities. After discussing with their families, they decided to courageously try IVF. However, after several failed attempts, they realized that traditional IVF might not be enough to solve their problem.
At this point, their doctor suggested they consider a combination of egg donation and surrogacy. Initially, Ms. Chen hesitated at the thought of using someone else’s eggs, as it seemed different from the way they had envisioned starting a family. However, after a thorough explanation from the doctor, they gradually came to understand that even though the egg came from a donor, the child would still grow up under their care and guidance. Blood relations are not the only bond—raising the child would form an even deeper parent-child connection.
With the help of COSTAIVF, they began to learn about the legality and scientific procedures of egg donation and surrogacy. Dr. Nathan Zhang explained every step of the egg donation process in detail, ensuring they understood the safety and legal protections involved at each stage. All egg donors undergo strict medical checks and health assessments to ensure that their eggs are not only healthy but also suitable for embryo cultivation. Furthermore, the entire surrogacy process is carried out within a strict legal framework, ensuring that the rights of the donor, surrogate mother, and future parents are fully protected.
Ms. Chen and Mr. Zhang ultimately decided to fulfill their parenting dreams through legal surrogacy. Soon, their embryo was successfully implanted in the surrogate mother’s womb, and the news of the pregnancy filled them with hope. Although they were not physically experiencing the pregnancy, they felt a growing connection with this new life during each checkup and every report of fetal movements.
With the help of the surrogate mother, Ms. Chen and Mr. Zhang finally welcomed their baby daughter. When they held their child for the first time, all doubts and uncertainties disappeared. Whether this child came to them through egg donation and surrogacy or through natural conception, the little life before them became their entire world. It was a feeling of indescribable happiness, and they felt grateful to everyone who helped them along the way.
