Research & Publications

Carlos A Guerrero, Ph.D, our Laboratory Director at Fertility Specialists of Texas, is actively involved in novel research studies to improve current embryology technologies and in vitro fertilization success. He has authored and presented several research publications at the prestigious American Society for Reproductive Medicine Conference (ASRM) during the past years.

Recently, seven new novel research studies were published and presented at ASRM 2010. Dr. Guerrero's main recent focus has been on improving oocyte (egg) and blastocyst freezing technologies using novel vitrification (fast freezing) protocols.
