OUR STORY
Reprovantage is the product of the collective vision of husband and wife laboratory specialists Ted and Charlene Tollner. Their 30-year professional journey in research and clinical service has positioned them to identify and meet a growing need in reproductive medicine. Reprovantage was founded in Sacramento County in 2018 as a Research and Development company with the goal of developing superior techniques for the long-term preservation of sperm specimens as well as mechanisms for improving access to sperm cryopreservation services. Today, our one-of-a-kind mobile lab operation places full semen evaluation and sperm cryopreservation capabilities near to point of care, powerfully serving male patients who will either undergo fertility altering medical treatment or who are otherwise at risk for loss of fertility.
OUR LEADERSHIP
Charlene received her training at UC Davis in the division of Reproductive Biology and has been an andrologist and laboratory manager for over 30 years. Charlene ran the lead laboratory for a number of multi-site, multi-national studies on the impact of industrial chemicals on male fertility and has contributed to chapters in two editions of the WHO Laboratory Manual for Semen Analysis. Charlene envisioned a program dedicated to male fertility preservation in 2012 when she recognized how many IVF centers are often unable to accommodate urgent requests for cryopreservation of semen of men and male teens scheduled for cancer treatment. She has spent the subsequent years considering what policies and procedures would make male fertility preservation more accessible, convenient, and discrete.
Charlene Tollner
President & Head of Operations
Ted received his doctorate from UC Davis in Molecular, Cellular and Integrated Physiology with an emphasis in Reproductive Biology. He has been a researcher in the field of sperm biology, sperm cryobiology, and primate fertilization at UC Davis for over 25 years, He has published in Nature, Science, Human Reproduction, Biology of Reproduction, Fertility and Sterility, among other peer-reviewed biomedical journals. Ted has served as a laboratory director for two IVF centers and as a technical adviser to numerous companies servicing infertility specialists. Ted brings his expertise in research and his love of science to Reprovantage. He is continually optimizing methods for sperm cryo-preservation and developing novel assays to appraise sperm function following freezing and thawing.
Ted Tollner
Director of Tissue Bank & Research
John received his MD and PhD from UC Davis. He is a male infertility specialist and pioneer in the microsurgery of vasectomy reversals. John has counseled and treated infertile and sub-fertile men for over 30 years, and has performed thousands of procedures, including testicular and epididymal sperm extractions for IVF and fertility preservation. His practice has helped countless couples achieve pregnancy. John has collaborated with Ted on clinical studies evaluating the relevance of semen parameters and the sperm surface molecules on male fertility. John has teamed up with Charlene and Ted, providing Reprovantage with his clinical expertise and guidance with optimizing protocols for peri-surgical assessment and processing of extracted male tissues.
