Michael L. Norton, MS, Andrologist

Andrology and Endocrinology Lab Supervisor

Mike graduated with his BS in Biology from California State University Fullerton in 1991 and immediately began his Masters degree in Biology from the same university, graduating in 1995. For his thesis topic, Mike explored the molecular events during fertilization in the marine organism Ascidia ceratodes.

After receiving his Masters degree, Mike began to work on the MicroSort research project at Genetics and IVF Institute (GIVF). MicroSort is the only scientifically proven technique to separate X-bearing sperm from Y-bearing sperm as a gender selection method for X-linked disease prevention or family balancing. The MicroSort gender selection procedure is currently being used in several labs around the world.

In 2000, Mike became the Andrology Lab supervisor at GIVF and was mentored in clinical andrology by Dr. Richard Sherins, a previous president of the American Society of Andrology. In 2006, he moved to Columbia Fertility’s Andrology Lab and developed a custom database solution for the lab. In September 2007, Mike was recruited by the Reproductive Care Center to supervise the Andrology and Endocrinology Labs.
