Hi Afterglo,
My experience with seeds was somewhat different from what others in this forum have had. I had the usual after effects from the seeds - difficult urination, burning, etc. for a while. They gradually disappeared. However, in my case, which appears to be very unusual, the seeds failed and I am now on Lupron hormonal therapy. I have also had some serious problems with radiation proctitis (inflammation in the rectum with minor rectal bleeding), which was treated with hyperbaric oxygen therapy - that helped and I am now stable (i.e. better). See my history below.
Despite that, I would choose the same procedure again - seed implants. Because of your husband's age, I would favor the seeds. As you have probably read in the forum posts, prostate removal is not without its own risks and side effects. However, it is his and your decision. I wish you both only the best.
