Testosterone and prostate size

Testosterone makes prostates grow larger and makes prostate cancer grow more quickly.
I came across a study that looks at prostate size and testosterone levels:

Relationship between Serum Testosterone and Measures of Benign Prostatic Hyperplasia in Aging Men – Abstract

In our study, the serum testosterone levels in aging men did not correlate with the measures of BPH, including prostate volume and IPSS, regardless of whether total, free, or bioavailable testosterone was used. Age correlated with the measures of BPH, especially prostate volume. Additional large studies are needed to confirm these preliminary results.

To my surprise, patients with higher testosterone levels did not have larger prostates. As expected, patients with higher PSAs and older patients had larger prostates.

    I actually have a different question. I recently had robotic removal of the prostate at the Univ of AL at Birmingham. In my “research” I thought I”d found multiple references that state the vas deferens is “connected to the bladder” & semen then expels via that route. However, I have found out that the vas was just simply LIGATED & is not attached to anything. Is “anyone” actually anastamosing the vas deferens to the bladder?

    I am not aware of anyone reconnecting the vas to the bladder. The ejaculate fluid comes from the prostate and seminal vesicles. There isn’t much fluid coming from the vas.
    If you have any references, please post them.

    I think there is growing evidence that LOW testosterone my be more of a factor in prostate cancer than high levels are. This was only one study, but it does open the door to more discussion.
