Stem cell research provides hope for infertile cancer survivors
Date:12/10/2012

er understand the optimal timing of transplantation, how to prepare testicular stem cells for transplantation and make them safe for transplantation, and how to maximize their ability to restart sperm production."

But it's hard for researchers to know when clinical trials will begin since the removal and storage of spermatogonial stem cells is currently a rare practice worldwide.

"There are currently only a handful of clinics around the world that will remove and preserve testicular stem cell samples from prepubertal patients, and that limits the availability of candidates," said Hermann. "Until more clinics get on board and save stem cells for patients, we are limited in what we can do to test transplantation in clinical trials."

Hermann joined the UTSA College of Sciences' faculty in summer 2011, following a post-doctoral fellowship at MWRI alongside Associate Professor Kyle Orwig. At UTSA, he is continuing to focus his research on basic and translational studies of spermatogonial stem cells to preserve fertility in boys treated for cancer and related diseases.

"For a long time, oncologists have been unable to address the long-term consequences of life-saving chemotherapy and radiation treatments such as infertility," said Hermann. "That is now beginning to change as laboratory research such as this study provides new experimental options for patients facing infertility after cancer."
