“…In the current study the total and free testosterone levels were significantly lower among workers exposed to noise level above 85dB.The levels of serum total and free testosterone levels were lower in 15 workers (28.8%) of group A for both parameters compared to group B who were completely normal and the differences were statistically significant (p< 0.05) as shown in (Table 3). Dzhambov (2016) reported in his study on chronic noise exposure and testosterone deficiency that exposure to loud noise was associated with lower TT, but the effect was statistically significant only among those aged ≥37 years. Also, study done by Chamkoori et al (2015) on the effect of noise stress on the hormonal and semen analysis parameters in industrial workers of Bushehr, Iran showed a significant decrease in concentration of testosterone, LH and FSH and major changes in sperm parameters among workers exposed to noise from 85dBA to 119 dBA.…”

“…The hypothalamic-pituitary-testicular (HPT) axis is sensitive to gonadotropic hypogonadism. Occupational and environmental noise act as stressors and stimulate the HPA (Hypothalamicpitutary-axis), and have been implicated as a risk factor for testosterone deficiency (Dzhambov et al, 2015) Occupational noise exposure was associated with significantly lower total and free testosterone in active male workers aged 16-85+ years in the US general population (Dzhambov, 2016). Low testosterone is a risk factor for cardiovascular disease, obesity, diabetes, bone mineral density loss, depression, impaired cognitive and social functioning, and overall mortality (Zarotsky et al, 2014).…”

Introduction: Noise exposure is a common risk factor for many health adverse effects like hearing impairment, cardiovascular diseases and psychosocial dysfunction. Hypercholesterolemia is suspected to be the main factor for the pathogenesis of prolonged noise-associated cardiovascular extra-auditory effects of occupationally-induced noise. Occupational stress and noise exposure were associated with lowering of total and free testosterone in active male workers which in turn was considered as a risk factor for cardiovascular disease, obesity and many other diseases causing overall mortality. Aim of work: To evaluate the environmental measurement of occupational noise intensity at different units of concrete pipes industry and to assess the effect of occupational noise exposure (either auditory or extra-auditory) on the exposed workers with emphasis on cardiovascular symptoms, serum cholesterol and testosterone levels. Materials and methods: A comparative cross sectional is conducted upon 105 male workers in a company for reinforced concrete pipes at Cairo, Egypt. The study group ages ranged from 24-60 years. Duration of work ranged from 2-40 years. The workers are classified into two groups: group (A): 52 workers who are exposed to high level noise ≥ 85dB, and group (B): 53 workers who are exposed to low level noise < 85dB.Both groups were interviewed using specially designed questionnaire with emphasis on occupational history ,cardiac history ,history of hearing impairment and sleep disturbances .Clinical (general and systemic) examination was done. Laboratory investigations were performed including serum total cholesterol level, total and free serum testosterone levels. Results: The prevalence of hearing impairment was significantly higher among workers exposed to noise level above 85dBA (61.5% ) as well as the prevalence of cardiac symptoms as palpitation , ischemic heart diseases and history of catheterization were significantly higher among workers from group (A) (53.8%, 40.4% and 15.4% respectively). The levels of total serum cholesterol were significantly higher among workers exposed to noise levels above 85dBA (odds Ratio = 17.6) while total and free testosterone were significantly lower among the same group. Conclusion: The current study revealed that exposure to chronic occupational noise above 85dBA was associated with hypercholesterolemia that leads in turn to cardiovascular disorders and also associated with low levels of serum testosterone hormone.

“…A study by Min and Min in 2017 found that after controlling for age, residential area, and other lifestyle factors, while small 1 decibel increases in daytime or nighttime noise was not associated with increased risk of infertility, men exposed to increased noise levels at the second to fourth quartile had significantly increased odds of infertility (P<0.05) (87). It was hypothesized that increased risk for infertility in men exposed to high levels of noise pollution may be due to activation of stress responses and alterations in the hypothalamic-pituitary-gonadal (HPG) axis with ultimate suppression of testosterone (87,88).…”

Idiopathic infertility is the most common individual diagnosis in male infertility, representing nearly 44% of cases. Research studies dating over the last half-century consistently demonstrate a decline in male fertility that is incompletely explained by obesity, known genetic causes, or diet and lifestyle changes alone. Human exposures have changed dramatically over the same time course as this fertility decline.Synthetic chemicals surround us. Some are benevolent; however, many are known to cause disruption of the hypothalamic-pituitary-gonadal axis and impair spermatogenesis. More than 80,000 chemicals are registered with the United States National Toxicology Program and nearly 2,000 new chemicals are introduced each year. Many of these are known toxins, such as phthalates, polycyclic aromatic hydrocarbons, aromatic amines, and organophosphate esters, and have been banned or significantly restricted by other countries as they carry known carcinogenic effects and are reproductively toxic. In the United States, many of these chemicals are still permissible in exposure levels known to cause reproductive harm. This contrasts to other chemical regulatory legislature, such as the European Union's REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations which are more comprehensive and restrictive. Quantification of these diverse exposures on an individual level has proven challenging, although forthcoming technologies may soon make this data available to consumers. Establishing causality and the proportion of idiopathic infertility attributable to environmental toxin exposures remains elusive, however, continued investigation, avoidance of exposure, and mitigation of risk is essential to our reproductive health. The aim of this review is to examine the literature linking changes in male fertility to some of the most common environmental exposures. Specifically, pesticides and herbicides such as dichlorodiphenyltrichloroethane (DDT), dibromochloropropane (DBCP), organophosphates and atrazine, endocrine disrupting compounds including plastic compounds phthalates and bisphenol A (BPA), heavy metals, natural gas/oil, non-ionizing radiation, air and noise pollution, lifestyle factors including diet, obesity, caffeine use, smoking, alcohol and drug use, as well as commonly prescribed medications will be discussed.
