Proper and sufficient sleep is a fundamental component of healthy lifestyle.
Multiple factors interfere with the proper amount of sleep each person needs and it varies by age, 7-8 hours per night usually is enough for most adults.
In developed countries sleep disturbance and lack of enough sleep is becoming an increasingly common problem , and that is important not only for social reasons but also for other health disorders related to humans such as heart problems and possible impairment of male reproductive functions.
Studies have shown that lack of enough sleep might interfere with immune function by interfering with the levels of IgG, IgA and IgM.
The relationship between sleep duration and reduced sperm quality has been studied extensively, with much less studies on the relation to the production of anti-sperm antibodies.
Numerous studies have shown that men who slept poorly had lower sperm counts and higher percentage of abnormal sperms.
A comparison between selected group of males which were selected according to certain criteria with the evaluation of the effect of duration of sleep and bedtime on sperm count and quality was done with the establishment of good and regular sleep duration and ideal bedtime for six months before the starting of the study with the exclusion of any other psychological or physical disorders , it showed that sperm count and survival were significantly low in all short sleepers and most of long sleepers ( more than 9 hours of sleep each night for adult is considered long sleeping ) .
