Among older males, less sleep is associated with low levels of testosterone, according to a recent study. Normally, the levels of the male hormone decreases with age, and in some men, this may result in a lack of energy or libido. Researchers noted that some men manage to maintain normal levels of testosterone even at the age of 85-years-old. There is a large variation in the levels of testosterone in different people as they age, and the present study suggests that men who obtain less amounts of sleep during the night have a higher risk of developing lower levels of testosterone.
In this study, the researchers measured the levels of testosterone in the participants in the morning. The study was conducted on 12 healthy participants who were between the ages of 64-years-old and 74-years-old. The researchers also monitored the sleep of the participants for over a week.
The results showed that the levels of testosterone were related to the amount of sleep. The more sleep the participants received resulted in higher testosterone levels. Researchers claim that the findings of the study indicate the major changes in the body due to the hormone signals. The importance of the relationship for the health of the older adult males may be known only from further studies. The results of the study are published in the journal called Sleep.
