Does testosterone gel work to normalize serum levels in ICU patients with Hypogonadism?

None of the sources provided look at testosterone gel use in intensive care unit (ICU) patients. So there is no direct answer to whether a gel normalizes serum testosterone levels in that specific setting. What the sources do show is that testosterone gels, applied to the skin, can raise serum testosterone into the normal range in men with hypogonadism (low testosterone) in general outpatient settings ⁷⁹¹⁰. Whether that carries over to critically ill ICU patients is a separate question that these sources do not address.

What the research says

For transdermal (skin) testosterone products like gels and creams, serum testosterone levels rise in proportion to the dose given, and those levels track with clinical response ⁷. A review of Testim 1% gel found that in a 12-month study of 371 men with hypogonadism, total serum testosterone was raised to and kept within the normal range ⁹. In another study, men who had not reached normal levels on one gel were switched to a 2% testosterone solution, and 95% (72 of 78) reached a normal serum level, with a median level of 495.7 ng/dL, about a threefold rise from baseline ¹⁰.

What to ask your doctor

• Ask whether testosterone gel has been studied specifically in ICU or critically ill patients, and what is known about how illness affects hormone levels.
• Ask how serum testosterone would be monitored during treatment and what target range your care team would use.
• Ask about the known risks of testosterone therapy, including the fracture signal seen in a meta-analysis ⁵, and how those apply to your situation.
• Ask whether other hormone-related factors (such as how the body's own testosterone signaling is suppressed during therapy ⁴) matter for your care.
• Ask what the plan is for adjusting or stopping treatment as you recover.
