Per the PFSFoundation, the The “objective of the study is to determine why PFS patients develop sexual dysfunction.”
It’s methods include: To (i) evaluate sexual and psychological function, (ii) assess hormone levels, (iii) measure penile hemodynamic and sensory parameters, (iv) study androgen receptor genetics and gene expression, and (v) and determine gene expression patterns and profiles.
I would say it’s an extremely important study. Its goal is to figure out why we’re messed up sexually. However, based on the methodology overview, it seems like it will only attempt to answer this question from a genetic/receptor point of view. I think this could mean that we could be disappointed if the genetic/receptor studies are inconclusive, or if genetic/receptor problems are not our issue.
I believe it is the biggest study yet, or at least the biggest one that is trying to answer the “why/how” of PFS. Best case scenario, they find out what is wrong with us. Worst case scenario, they come up with nothing.
