Recently published data suggests that male fertility has declined over the past four decades. The reasons for the decline are unclear with up to 50% of cases of male infertility remaining unexplained (idiopathic male infertility). Whilst environmental factors and rising rates of obesity have been implicated, there is now growing evidence that sleep disturbance may be an independent causative factor. Indeed, the prevalence of sleep disturbance appears to be increasing in parallel with deterioration in population sperm quality, a commonly used surrogate marker of male fertility.

ConclusionThe major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking conception.

AbstractPurpose of ReviewNon-standard shift work schedules negatively impact the overall health of shift workers, and several studies have shown that shift work, specifically, is detrimental to urogenital health. The aims of this study are to systematically review the literature and determine the effect of shift work on the outcomes of hypogonadism, male infertility, lower urinary tract symptoms, and urogenital cancers.Recent FindingsRecent evidence supports associations between non-standard shift work and an increase in the frequency of prostate cancer and the severity of erectile dysfunction, lower urinary tract symptoms...

Testosterone deficiency has been linked to several adverse health outcomes - including cardiovascular disease, erectile dysfunction, and metabolic syndrome. Recent data has suggested that abnormal sleep quality may result in lower testosterone levels. Using the 2011- 2012 National Health and Nutrition Surveys (NHANES) we assessed the effect of self-reported sleep patterns on serum testosterone while controlling for physical activity levels, co-morbidities, and baseline demographics.

General health and lifestyle factors can impact male reproductive health. In May 2015 we launched a 30-question online fertility risk assessment questionnaire of established male fertility risk factors based on a literature review, including age, body size, medical history, diet, exercise, sleep, and exposure to known toxins. A summary ″risk score″ was calculated by weighting responses from each man based on literature studies and a priori assumptions on risk of male infertility, subfertility, and sperm quality.

Melatonin is a sleep inducing hormone and a hormone of darkness, secreted by the pineal gland. It has a role in idiopathic oligoasthenoteratozoospermia (iOAT) male infertility by its potent antioxidant effect. We aim to estimate seminal plasma and serum melatonin levels in iOAT patients compared with normal fertile male patients and the effect of exposure to light at night on their semen parameters.

Men and women follow the Wheat Belly lifestyle and can undergo important and sometime startling hormonal changes. Though results vary with stage of life—young adults, middle-aged, older—there are a variety of hormonal changes that women and men typically experience, some in concert, others independently. Such hormonal shifts can be powerful and part of the health-restoring menu of changes that develop with this lifestyle. They can even improve a relationship in a number of ways, both physically and emotionally, especially if we weave in some of the newer Wheat Belly/Undoctored concepts and practices such as oxy...

Authors: El Salam MAA Abstract Obesity is a highly prevalent non-communicable disease worldwide and is commonly associated with male infertility. Several etiopathological theories have been mentioned in the literature by which obesity affects spermatogenesis, thus affecting the male fertility potential. Mechanisms for explaining the effect of obesity on male infertility include endocrinopathy, increased aromatization activity, associated erectile dysfunction, psychological and thermal effects, obstructive sleep apnea, increased leptin and oxygen free radicals, and associated inflammatory and obstructive elements of...

A surprisingly common reason for the inability to have a child in today's modern world is infrequent sex. Now, this may seem surprising in this day and age when you expect everyone to be so sexually aware. However, people living in large metropolises are so stressed out that they simply don't have time to have sex ! They spend three hours or four hours commuting everyday, so that by the time they come back home , they are dead tired. Thanks to the mobile, they are always " on call", and have tons of work which they have brought from the office to complete, along with replying to emails and returning calls. Y...
