Sleep deprivation can cause fatigue and cause lack of interest between the partners, say experts. They also opine that melatonin can influence sexual drive.

Lack of sleep may prevent the body from producing enough hormones to keep the libido in check. The connection between sleep and libido is complicated, experts say.  In some cases, lack of sleep can cause mental and physical exhaustion, decreasing libido.

Sleep deprivation may lead to unhealthy lifestyle choices, such as a poor diet and reduced libido. Lack of sleep has also been associated with a decrease in testosterone in men, which is linked to libido or sex drive.
