As men age, a decline in testicular production of testosterone are seen, as well as an increase in sex hormone binding globulin, both of which act to decrease bioavailable testosterone. In many people, the cause is temporary or related to conditions like dehydration, sleep apnea, lung issues, or smoking. Many common conditions—such as dehydration, sleep apnea, smoking, or living at altitude—can temporarily or chronically raise these values. Chronic alcohol abuse can also cause increased blood pressure, poor sleep, and other barriers to strong erections. To our knowledge, this is the first systematic review and meta-analysis assessing differences due to CPAP use in eugonadal and hypogonadal patients with OSA syndrome, as well as focusing on gonadotropins. The overall results of our meta-analysis showed that CPAP does not influence total testosterone or gonadotropins. Data were available for 95 patients with hypogonadism and 280 with eugonadism at baseline. Qualitative analysis of studies included in the systematic review. Moreover, 49 patients were treated with sham-CPAP, 21 with mandibular advancement devices, and 12 with CPAP and simultaneous TRT; they were not included in the present review.

Use the RISE app to find out your individual sleep need and how much sleep debt you have. You should especially prioritize sleep in the second half of the night as this is where most REM sleep happens. The higher your AHI, the more apneas (when you stop breathing) and hypopneas (when breathing becomes shallow) you experience each hour. As men get older, their testosterone levels naturally start to drop. Further studies are thus needed reporting data on sleep duration, compliance to CPAP, months of use, OSA syndrome improvement, and BMI. Concerning the latter aspect, it is estimated that CPAP is not able to correct all the nocturnal events in about 20% of patients with OSA syndrome; the risk is increased in patients with concomitant obesity hypoventilation syndrome and chronic obstructive pulmonary disease (54). It is worth noting that other treatments, such as diet and bariatric surgery, proved to increase total as well as serum free testosterone and SHBG (40). The primary outcome was the change in serum total testosterone levels from baseline to the last available follow-up. Thus, we performed a systematic review and meta-analysis to evaluate the effects of CPAP on serum testosterone and gonadotropin levels in male patients with OSA syndrome. Sleep apnea, specifically obstructive sleep apnea syndrome (OSAS), is closely linked with an elevated risk of cardiovascular conditions. If you suspect that you have sleep-related issues or experience symptoms related to low testosterone, consult a healthcare provider for a thorough evaluation. If you have been diagnosed with hypogonadism, testosterone replacement therapy (TRT) may be considered to manage low testosterone levels. While you sleep, your body performs many vital functions, including the regulation of sex hormones such as testosterone. Obstructive Sleep Apnea (OSA) can disrupt your normal sleep patterns, often leading to reduced serum testosterone levels. The symptoms of OSA include loud snoring, daytime sleepiness, morning headaches, and observed episodes of stopped breathing during sleep. Sleep apnea, particularly obstructive sleep apnea (OSA), is a chronic condition that impacts your sleep quality through intermittent pauses in breathing. It helps with many important functions like building muscle, keeping bones strong, producing red blood cells, and supporting a healthy sex drive. Testosterone is a hormone that plays a major role in a man’s health. In all, a limited number of studies specifically focusing on the effect of CPAP in hypogonadal patients was found, and this prevented any additional analysis (e.g., meta-regression) to explore the high heterogeneity of findings. Two studies included such patients, but no information other than a "medical history" evaluation is reported (9, 20). Lastly, it should be considered that pituitary imaging in patients with serum total testosterone 11). Also, CPAP adherence is usually defined as hours per night rather than as a proportion of total sleep time, which is usually not measured. Sleep apnea and low testosterone are two conditions that often happen together in men. The link between these two issues shows the importance of looking at the body as a whole system, not just one part at a time. Breaking this cycle—through proper diagnosis and treatment—is key to improving health. If sleep keeps getting cut short, the brain may not send the right signals to produce enough hormone. TRT does not appear to increase cancer recurrence in hypogonadal men following radical prostatectomy. For men who have previously undergone definitive treatment for prostate cancer, the usage of TRT is becoming more accepted. For premalignancy, prostatic intraepithelial neoplasia (PIN) appears to be a risk factor for developing prostate cancer, however this association has been mostly demonstrated for high-grade disease.26,27 There is a lack of long-term data on the use of TRT in men with PIN. This theory may explain why testosterone does not directly cause prostate cancer, but it has been shown to accelerate the development of prostate cancer.24,25 Morgentaler et al. proposed a saturation theory where prostate growth becomes insensitive to changes at normal androgen levels due to saturation of the androgen-receptor; however, there is exponential growth at castrate levels.
