In a corner of the city, there is a warm family. Mrs. Liu and her husband Mr. Zhang have been married for many years, with a deep affection and a happy life. However, their family is overshadowed by a genetic disease. Mrs. Liu's family has hereditary hemophilia, a bleeding disorder caused by a deficiency in clotting factors, which is primarily passed down through the X chromosome, usually affecting males while females are carriers. To prevent their child from inheriting this disease, they decided to seek third-generation IVF technology to choose the baby's gender and avoid the risk of genetic disease.
Mrs. Liu and Mr. Zhang came to COSTAIVF, seeking help from founder Dr. Nathan Zhang and his team. After understanding their situation in detail, Dr. Zhang tailored a fertility plan for them. They first underwent genetic screening, confirming that Mrs. Liu was a carrier of the hemophilia gene. Dr. Zhang then recommended third-generation IVF technology to perform embryo transfer, selecting female embryos that did not carry the hemophilia gene to avoid passing on the genetic disease.
With the meticulous guidance and assistance of Dr. Zhang and his team, Mrs. Liu underwent ovarian stimulation and successfully retrieved eggs. Through in vitro fertilization, embryologists combined Mrs. Liu's eggs with Mr. Zhang's sperm, forming multiple embryos. These embryos then underwent genetic screening, and healthy female embryos that did not carry the hemophilia gene were selected. Ultimately, Mrs. Liu became pregnant and welcomed a healthy little princess.
In addition to families like Mrs. Liu and Mr. Zhang who choose gender selection to avoid genetic diseases, there are many families with specific gender needs, hoping to achieve the dream of having both a son and a daughter. Mr. Wang and Mrs. Li are one such family. Already blessed with a lovely son, they hoped to have a daughter to fulfill their dream of having both a son and a daughter.
Mr. Wang and Mrs. Li came to COSTAIVF and expressed their wishes to Dr. Nathan Zhang. Dr. Zhang fully understood their sentiments and introduced the process of gender selection through third-generation IVF technology. After detailed consultation and medical examinations, Dr. Zhang formulated a personalized fertility plan for them.
Accompanied by the professional team throughout the process, Mrs. Li underwent ovarian stimulation and successfully retrieved multiple eggs. Through in vitro fertilization, these eggs were combined with Mr. Wang's sperm, forming multiple embryos. Subsequently, embryologists performed genetic screening on these embryos and selected healthy female embryos. Eventually, Mrs. Li became pregnant and welcomed their daughter, realizing their dream of having both a son and a daughter.
