Chaya Rothschild, Andrologist, Project Manager

Extended Sperm Search & Microfreeze

Chaya Rothschild holds a certification in both Andrology and Embryology Laboratory Sciences through the American Association of Bioanalysts Board of Registry. 

Her prior experience includes work at a fertility laboratory performing IVF and other procedures related to Assisted Reproduction. Her time there has shown her that male infertility is a factor that is largely underestimated as contributing to the success or failure of assisted reproductive treatment. Her skills and experience in the micromanipulation of reproductive cells make her a valuable asset to the new Extended Sperm Search Program at Maze Men’s Health.

Chaya has almost 10 years of experience with direct patient care, beginning with her time spent as a volunteer EMT in her hometown. She has found that the ART laboratory scientist is a unique blend of laboratory technician and clinician, with patient-centered care being fundamental to her approach.
