Work features

There are unique ideas and techniques in the field of in vitro fertilization embryo transfer. There are multiple original technological inventions: the invention of ultrasound assisted pelvic fallopian tube imaging in 1999; Invented tubal isthmus occlusion surgery in 2006; In 2007, the technology of mild stimulation IVF with letrozole was invented; Starting from 2008, the idea and method of natural cycle mild stimulation IVF were promoted to domestic peers; In 2006, China was the first to stop using programmed embryo freezing technology and fully adopt vitrification embryo freezing technology. In 2010, self-developed vitrification freezing reagents and freezing methods were commercialized. Discovery of luteal phase ovulation induction in 2009; In 2012, it was discovered that letrozole promotes ovulation induction responsiveness during the luteal phase; The invention of Progesterone Controlled Ovulation (PPOS) technology in 2013 was a milestone in ovulation control technology, laying the foundation for the treatment of difficult diseases. Has made many contributions in the research of difficult and rare diseases: collaborated with Wang Lei's team from Fudan University to discover the molecular genetic mechanisms of diseases such as egg maturation disorders, egg fertilization disorders, and egg death.
