The mystery around sperm counts

The sudden rise in male infertility is a scary national crisis. According to urologist and associate professor Michael Eisenberg, "Here is direct evidence that the function of reproduction is failing. We should try to figure out why that is." What we do know about declining sperm count tells us a great deal about not only reproduction but also the overall health of men - and what it tells us isn't good. Is it simply modern life iteself - obesity, inactivity, stress, close cellphones, even older parenthood that's driving down sperm levels? It's the beginning of an answer but not the full one.

Fathers of American newborns keep getting older

Michael Eisenberg, assistant professor of urology, is the senior researcher on a new study in the journal Human Reproudction, which reports that the average age of today's American dad is roughly 3.5 years older than his counterpart from four decades ago, growing from 27.4 years in 1972 to 30.9 years in 2015. The new study is quickly generating media attention and buzz around the internet:

Looking at the safety of Active Surveillance in monitoring patients with prostate cancer

James Brooks, professor of urology, is part of a team of researchers who received funding from the National Institutes of Health to use natural language processing to mine electronic medical records to identify patients with low risk prostate cancer who are managed by Active Surveillance.  In Active Surveillance, men with small, low risk cancers are followed with PSA tests, physical examinations and biopsies with the intention that they switch to either surgery or radiation therapy if their cancer becomes more aggressive.  Dr. Brooks is part of a national study of Active Surveillance in which they have found that approximately 2/3 of patients have cancers that do not progress and do not need treatment after 5 years of monitoring.  Identifying all patients on Active Surveillance at Stanford and elsewhere will allow Dr. Brooks and colleagues to look at the safety of Active Surveillance, understand variations in care patterns (e.g. how often patients get PSA tests and biopsies) and test whether other tests such as prostate MRI scans are helpful in managing patients.

Yes, sperm counts may be dropping, but it's not time to panic yet

Last week, a new study revealed an alarming drop in sperm counts for men Western countries. Does this mean men are becoming infertile? According to expert Michael Eisenberg, assistant professor of urology, "it should be seen as a wake-up call, but not necessarily the end of days."

Expert Michael Eisenberg, assistant professor of urology, agrees that the data have some flaws but says it’s enough to justify further investigation.

New article shows that there are extensive chemical modifications to the DNA of prostate cancers called DNA methylation

The changes are known to affect gene regulation, and we find that genes regulated by a specific protein, called EZH2, are particularly targeted by this chemical modification.  Furthermore, these methylation changes, since they are specific for prostate cancer, could form the basis of new tools to diagnose prostate cancer.

Article suggests importance of biopsy timing for men on active surveillance 

In a large study covering 10 institutions across the country, over 1400 men were enrolled with relatively low risk prostate cancer, and watched with PSA testing and periodic biopsies. The study reports that men who are obese have a higher risk for showing more cancer or higher grade cancer when they are biopsied after 1 year of surveillance.  Likewise, men who have a relatively small prostate and high PSA (high PSA density) also have a higher risk.  These men might need to undergo biopsy sooner when on active surveillance. See article highlight in the accompanying editorial in the Journal of Urology.

Guys: It’s now possible to test your sperm via smartphone

Michael Eisenberg, assistant professor of urology, says men are underserved when it comes to infertility testing, partly because it's "incorrectly seen as a woman's problem." In 20 to 25 percent of infertility cases, men aren't even evaluated. That could change, Eisenberg said, with home-based testing that made it easier and less anxiety-inducing to analyze a sperm sample.

Important study could lead to a new diagnostic tool that could be used to determine positive surgical margins in almost real time in the operating room

Geoff Sonn's recent publication in PNAS may enable more accurate diagnosis of prostate cancer by imaging metabolites to offer a rapid, almost real-time diagnosis for men undergoing prostate biopsy.

A new imaging technique, which works on any hollow organ, could help doctors better prepare for surgery

Advanced computer imaging technology has created a three-dimensional computer reconstruction of a patient's bladder. According to Joseph Liao, associate professor of urology, these three-dimensional images could help doctors prepare for surgery. “Sometimes you don’t have a sense – where was I in the bladder?” Liao said. Seeing a three-dimensional rendering of an organ before operating, like having a map before embarking on a trip, could make the procedure easier for doctors.
