![Introduction to Prostate Cancer
Prostate cancer remains the most commonly diagnosed cancer and second leading cause of cancer death among men in the U.S., with evolving screening and treatment practices reshaping care in 2025. Dr. Cornelia Ding explains how to read and understand a prostate cancer pathology report by breaking down its five key sections. Dr. Rahul Aggarwal explores how clinical trials improve prostate cancer care by advancing personalized treatment, increasing access, and correcting misconceptions about placebos. Dr. Jonathan Chou highlights the expanding role of precision medicine and how genetic insights guide individualized treatment based on each tumor’s molecular makeup. Dr. Eric Small explains how androgen deprivation therapy (ADT) targets the cancer’s dependence on testosterone and how newer therapies and combinations are improving outcomes, while also emphasizing the need to balance effectiveness with side effects through shared decision-making.

![A Noninvasive Test for Male Infertility
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=naEwn4ybv60
Men with non-obstructive azoospermia may undergo microscopic testicular sperm extraction, or mTESE, without knowing whether sperm will be found. Kun Tan, Ph.D., of UC San Diego explains how molecular semen analysis could provide a noninvasive way to predict the procedure’s outcome. The assay uses stage-specific germ cell markers identified through single-cell RNA sequencing, then measures those markers in semen with qPCR. Because semen contains germ cells from different stages of sperm development, their molecular signals may reflect what is happening inside the testes. Tan shows how the assay predicts whether sperm retrieval was successful and can identify where sperm development may be blocked. The research could help couples planning IVF or ICSI avoid unnecessary surgery, reduce financial and emotional burdens, and receive more detailed information about male infertility before treatment.

FAQ
Q: Can a semen test predict whether sperm will be found during mTESE?
A: Molecular semen analysis measures markers from different stages of sperm development. In the research presented, sperm-specific markers accurately predicted whether a previous mTESE procedure had successfully retrieved sperm.
Q: Why can a testicular biopsy fail to predict sperm retrieval?
A: Sperm production is not uniform throughout the testes. A biopsy taken from an area without active sperm development may not represent what is happening elsewhere in the tissue.
Q: How does molecular semen analysis work?
A: The assay uses qPCR to measure stage-specific germ cell markers in a semen sample. The pattern of those markers may show whether sperm are present and where the sperm development process has been disrupted.

![Cognitive Health and Resilience
Cognitive resilience grows from small, consistent habits that keep the brain adaptable. Fadel Zeidan, Ph.D., frames mindfulness as mental training that improves attention, processing, and the way people relate to pain. Erin E. Sundermann, Ph.D., underscores modifiable pathways to healthier aging, highlighting movement, social connection, hearing support, and lifelong learning as mutually reinforcing drivers of brain health. Raenne C. Moore, Ph.D., centers practical strategies that translate into daily life, including routines, planned breaks, reducing distractions, and attending to anxiety or depression. Carolyn Dunmore, an older adult community Mmmber, exemplifies resilience through steady activity, purposeful community roles, faith, self-compassion, and the “use it or lose it” mindset. Together, Zeidan, Sundermann, Moore, and Dunmore point to a clear theme: everyday practices accumulate to support memory, attention, and well-being as people age. Recorded on 09/25/2025.

UCSF experts present four major approaches to managing prostate cancer, each tailored to disease risk and patient needs. Dr. Peter Carroll explains how active surveillance uses MRI, PSA, and genomic testing to safely delay treatment in low-risk cases while preserving quality of life. Dr. Samuel Washington details prostatectomy, highlighting robotic-assisted surgery’s precision and its impact on recovery, fertility, and sexual function. Dr. Julian Hong outlines radiation therapy options like SBRT and brachytherapy, emphasizing targeted delivery to limit side effects and the importance of ongoing follow-up. Dr. Hao Nguyen introduces focal therapy, which treats only the tumor using techniques like cryotherapy or high-intensity ultrasound, helping patients avoid surgery or radiation while maintaining function and quality of life.
