PSA undetectable but testosterone remains negligible

Posted by anosmic1 @anosmic1, 2 days ago

Mostly good news from today's PSA test 7 months after the end of radiation. I'm age 68, Gleason 9, had RP in November 2024, 6-month Lupron injection in October (9 months ago) and 39 radiation treatments ending in February.

PSA is undetectable (<0.01) but testosterone remains almost nonexistent at <12. Reference range is reported as 240-1022. Saw the radiation oncologist today and he seems surprised that the testosterone score is so low still and that I continue to have hot flashes, probably 10-12 a day. He didn't take any new steps.

Next appointments are October with the urologist/surgeon and January with Red Onc.

I just returned from the surgeon with a PSA of 0.02 and he said he likes to see it at 0.01, so I am on track for a repeat PSA and visit to him in 2 months. He said, " that maybe some cells had jumped the gate", so as with a Gleason score of 3+4, I am at more risk than my brother, whose score was 3+3.

@anosmic1 The general rule of thumb for T recovery following ADT (with the exception of Orgovyx and Firmagon) is to expect it to take about 50% longer than the ADT was planned for.

In my case, I had two 3-month injections of Eligard (April & July); expected T recovery in October, but it didn’t recover for 3 additional months (January of the next year).

With your last injection in October, you’re right at that ~9 month mark. Your next PSA test will be telling.

It’s important to know your baseline T numbers. That helps in troubleshooting should your later PSA or T numbers become unusual.

(I recall telling my wife (in January 2022), that I thought the Eligard was wearing off because I was beginning to lift heavier weights at the gym. Since I wasn’t due for another “official” bloodwork for another couple of months, I self-ordered another PSA & testosterone test (out of curiosity), and those came back as 0.13 & 403.0, respectively, meaning that everything was going exactly as expected - that is, PSA staying low and testosterone increasing as the Eligard was leaving my system.)

@brianjarvis I can tell you that for me last Firmagon was Feb 2026. 5 monthly injections. I am still <7 on testosterone.

Hi,
Just have to keep an eye on it over the next several tests. Everyone is different on how they react to ADT drugs and how they; recover. Be very happy you are at the undetectable level👍.

15 months after my last 3-month Lupron shot and I have a 125 testosterone and of course no libido or erections. I was on Lupron for only 4 of the recommended 18 months but had to stop because of very severe and painful headaches, muscles and bones. I felt like I was dying and i think I would have if I had another Lupron shot. The side effects began to wane after 14 months, but they are still present.

@pesquallie What was your baseline T level; & how old are you?

Both of those often play a role in T recovery.

Almost same as you here. Gleason 9, 18 months of Eligard completed October '25. Still hot flashes galore and T level <0.4 (Normal range: 1.8 - 7.8 ng/mL). From what everyone is saying, it could take some time for the T to come back. Btw, I'm 63.

I don’t think many other doctors would think your PSA is too high. The medical standard for undetectable PSA is <.1. You are way below that. It would be more important to see if your PSA is rising them to make any comments at all about .02 being too high.

I think a second opinion would get very different side of what you’re hearing.

Thanks, great advice, I 've checked online sources and they reflect what you said.

Over the 10 years before Lupron, I averaged a testosterone level of 268, and I will be 84 this week. So, after 15 months since my last 3-month Lupron injection, I have regained about 50% of what was already a low testosterone level with major ED issues. I am now interested in ways where I can raise my testosterone to rid myself of all the side effects I still have.

@pesquallie Data show that older age results in significantly slower and less frequent testosterone recovery after stopping ADT compared to younger men. Recovery time also depends heavily on the duration of the hormone therapy and starting (baseline) testosterone levels.

Something else to discuss with your medical team —>
There is a school of thought that your "menopausal" symptoms (hot flashes, fatigue, and low libido, etc.) may not only be caused by low testosterone (due to hormone therapy), but also low estrogen that triggers many of these specific side-effects.
In men, a portion of testosterone is converted into estradiol (a form of estrogen). When testosterone drops (due to hormone therapy), the body's estrogen supply naturally drops with it. A chain of events occurs:
> a testosterone deficiency automatically means a lack of the building blocks needed to make sufficient estrogen.

> When men experience severe hot flashes, clinical studies have shown that administering estrogen alone minimizes their symptoms (https://pubmed.ncbi.nlm.nih.gov/10654902/; https://www.wellrx.com/news/estrogen-in-men/)

Again, something to discuss with your medical team.
