Since the world's first IVF-PGT birth in 1978, assisted reproductive technologies have made significant progress through global scientific collaboration. The IVF-PGT treatment process includes controlled ovarian stimulation, egg retrieval, fertilization, embryo culture, and cryopreservation. Success is defined not only by achieving expected outcomes at each stage but also by ensuring low risk, high safety, and a satisfactory final treatment outcome.

 

The European Society of Human Reproduction and Embryology (ESHRE) defines success rates in ART with several key points: full-term, single live birth, vaginal delivery, normal birth weight, and no congenital malformations. Additionally, success is measured by the shortest treatment-to-pregnancy time, minimal expenses, patient discomfort, and lowest risk of complications.

 

A complete cycle refers to a fresh embryo transfer following controlled ovarian stimulation and subsequent transfers of all frozen embryos. Cumulative delivery/live birth rates represent the chances of successful delivery after one complete cycle of treatment, helping establish realistic treatment expectations. If fresh transfers are unsuccessful, pregnancy can be achieved through frozen embryo transfers. Some patients aim for more eggs to achieve success in one retrieval, but retrieving more than 15-20 eggs may increase the risk of ovarian hyperstimulation syndrome, emphasizing treatment safety as the foundation of success.

 

Shortening the time from treatment to pregnancy makes it easier for patients to accept and adhere to treatment, a shared goal of doctors and patients. Doctors advise on embryo transfer based on the patient's current conditions, as overly pursuing speed may lead to failure. The rate of multiple pregnancies increases with risks such as preeclampsia, preterm birth, and neonatal intensive care, underscoring the importance of reducing multiple pregnancy rates in IVF-PGT success.

 

Success in IVF-PGT is a complex issue aimed at helping infertile families conceive healthy babies. Achieving this goal requires coordinated diagnosis and treatment across departments such as urology, gynecology, obstetrics, rheumatology, immunology, and traditional Chinese medicine, ensuring the safety of the entire pregnancy process. In IVF USA, clinical doctors, laboratory scientists, and geneticists collaborate closely, where success depends not only on individual doctor's experience and capability but also on team and overall technological coordination.

Ultimately, improving assisted reproductive success rates requires focusing on preventive care for infertility, reducing complications, and helping couples successfully conceive healthy babies.
