There were no relationships of ODI to the testosterone levels,35 but positive correlations were observed between changes in serum testosterone and hyperoxic ventilatory recruitment threshold and between changes in hyperoxic ventilatory recruitment threshold and time spent with oxygen saturations during sleep at 6–7 weeks but not at 18 weeks.36 In old as compared to young rats "paradoxical sleep deprivation" results in a greater decrease in testosterone and recovery is delayed.14 Other factors such as concomitant circadian shifts, changes to sex hormone binding globulin (SHBG), circadian rhythm disruption, induction of stress, depression, medication, and the use of self-reported as opposed to objectively assessed sleep duration may also explain differences between epidemiological studies. Plasma testosterone levels display circadian variation, peaking during sleep, and reaching a nadir in the late afternoon, with a superimposed ultradian rhythm with pulses every 90 min reflecting the underlying rhythm of pulsatile luteinizing hormone (LH) secretion. Poor sleep can work directly against healthy testosterone function because sleep and hormonal recovery are closely linked.When researchers at the University of Chicago restricted young men to five hours of sleep a night for one week, their testosterone levels fell 10-15%. Although limited data suggests that treatment of OSA by CPAP or palatal surgery results in an increase in morning plasma testosterone levels at 3 months, the majority of other studies show that CPAP applied for durations that range from a single night26 to 39 months is without effect on luteinizing hormone (LH), follicle stimulating hormone (FSH), or testosterone even when compliance is assured.27 A summary of the studies looking at the effect of CPAP on plasma testosterone in men with OSA is shown in Table 1.27,28,29,30,31,32 There is, however, a relationship between disturbed sleep and wakefulness, increased need for sleep and recovery, reduced morning cortisol, lower testosterone levels, and dissatisfaction with the shift system. Superimposed on this are burst-like increases in testosterone production that occur every 90 min or so.2 Plasma testosterone levels begin to increase with the onset of sleep, and in young men peak at the first REM sleep episode and remaining at that level until waking;3 the longer the REM sleep latency the slower the rise in testosterone.4
Whether you are experiencing ED or boredom in the bedroom, both you and your partner should communicate about your sexual needs and desires. Lifestyle plays a fundamental role in sex health and erectile function. Erectile function requires coordination between your brain, blood vessels, and nervous system. The author has received research support from Resmed Foundation, Bayer Schering, Eli Lilly, and Sanofi Aventis. OSA per se is not a cause of low testosterone, rather it is due to obesity, and is increased by weight loss but not CPAP.
Light exposure, food choices, caffeine timing, room setup, and alcohol all affect how well you recover overnight. If you stay wired into the evening, it is harder to fall asleep and stay asleep. When sleep is short, broken, or inconsistent, next-day energy, libido, focus, and training drive often take a hit. Many of those inputs are shaped in the last few hours of the day. This guide covers practical evening routines for men who want better energy, stronger training, sharper focus, and faster recovery. You can train hard and eat well, then still stall out if your nights are chaotic.
Below, we’ll answer your testosterone and sleep questions and show you how the RISE app can help you improve your sleep and perhaps your testosterone levels, too. So, it may be that you’re sleep deprived and fixing this problem could improve your symptoms and ensure your body can make all the testosterone it needs. But, what many of us don’t know about testosterone is that not getting enough sleep can drastically lower your production of the hormone.
When symptoms do occur, low testosterone can cause a range of effects. Testosterone administration may cause you to develop sleep apnea, or it may contribute to worsening symptoms if you already have the sleep disorder. Having high levels naturally has been linked to more shallow sleep and feeling more tired after sleep deprivation. Testosterone-treated mice get more sleep when their natural levels were low. Even if sleep debt and fragmented sleep aren’t the reason for low testosterone, fixing them will lead to increased energy, mood, and productivity.
Testosterone levels vary through the day and are linked to your circadian rhythm—regular body changes over a 24-hour period. We’ll explore the relationship between testosterone and sleep below. Testosterone is a sex hormone that’s naturally found in the body. Your daily habits and environment can significantly impact the quality of your sleep.
