Of diamond surfaces, red light photobiomodulation and fertility: lessons from the laboratory

There is hardly a day that goes by in my various professional roles as scientist, science watcher or clinician without encountering new information or a new scenario that highlights the complexity of biology and biological systems. Such occurrences warrant careful evaluation and oftentimes lead to new management strategies or form the basis for further scientific investigation. This is inevitable as the knowledge base expands and our understanding of the variables potentially impacting our strategies and outcomes increases. We continually learn, re-learn and refine what we do and how we do it. The survival and performance of human spermatozoa in vitro is one evolving story that has far-reaching implications in numerous fields in addition to human reproduction.
