Pearls & Perspectives: The Present and Future of Male Fertility Testing, With Dolores J. Lamb, PhD

Welcome back to Pearls and Perspectives!

In this episode of Pearls & Perspectives, host Amy Pearlman, MD, is joined by renowned male reproductive specialists Larry I. Lipshultz, MD, and Dolores J. Lamb, PhD, to discuss the science, clinical value, and future of the male infertility laboratory. Drawing on decades of collaboration in reproductive medicine, the conversation highlights the critical role of high-quality andrology laboratories in the evaluation of male infertility and explores how laboratory innovation has shaped clinical practice. Beyond the technical aspects of semen analysis, the discussion emphasizes the importance of close collaboration between laboratory scientists and clinicians to improve diagnostic accuracy and patient care.

The conversation examines the continued central role of the semen analysis while underscoring its limitations and the importance of proper specimen collection. Lamb outlines common pitfalls—including inadequate abstinence periods, incomplete sample collection, and improper handling—that can significantly affect results. The experts also weigh the growing popularity of at-home and mail-in semen testing, acknowledging that while these tools may encourage men to seek evaluation, challenges related to specimen quality, temperature fluctuations during shipping, chain of custody, and interpretation can limit their reliability. They stress that comprehensive evaluation by a reproductive urologist remains essential, particularly for fertility preservation before cancer treatment.

Pearlman, Lipshultz, and Lamb also explore the growing recognition of male infertility as a broad marker of men's health. They discuss evidence linking impaired fertility with an increased risk of systemic diseases, including cancer, and explain how abnormalities in spermatogenesis may reflect underlying genetic and biologic processes. The conversation highlights the need for greater awareness among both clinicians and patients that infertility evaluations can provide insights extending well beyond reproductive potential.

Looking toward the future, the group discusses emerging genetic and molecular approaches that could fundamentally reshape male infertility diagnostics. Lamb reflects on her pioneering work in sperm aneuploidy testing and argues that advances in genetics, artificial intelligence, and other emerging technologies may eventually move the field beyond reliance on conventional semen parameters alone. Although questions remain regarding cost, accessibility, and clinical implementation, the experts envision a future in which genetic and molecular profiling becomes an increasingly important component of routine male fertility evaluation, offering more precise diagnoses and better-informed reproductive counseling.
