Biological Responses of Mobile Phone Frequency Exposure
Published in Jitendra Behari, Radio Frequency and Microwave Effects on Biological Tissues, 2019
A related issue is the corresponding effect on male infertility. A study carried out in Poland (Wdowiak et al. 2007) on the population using mobile phone (GSM equipment) spread over a period of 1–2 years has found their sperm quality affected. They reported a decrease in the percentage of sperm cells in vital progressing motility in the semen as well as their structure is correlated with the frequency of using mobile phones. These two findings seem to be mutually consistent.

Medical history, clinical examinations, and sperm analysis should be the primary step in infertility evaluation (Figures 7 and 9). The semen analysis may be considered the most important test in the evaluation of male infertility, even though it is difficult to define a normal fertile ejaculate. There is no sharp line between fertility and infertility insofar as the parameters of semen quality are concerned.
Glossary of scientific and technical terms in bioengineering and biological engineering

Sperm disorders refer to the condition with the production and maturation of sperm; the single most common cause of male infertility. Sperm may be immature, abnormally shaped, unable to move properly, or, normal sperm may be produced in abnormally low numbers (oligospermia).

The number of people who seek help from specialized infertility centers increases, yearly, by 8-9%. However, there is no accurate evidence that the problem itself (i.e. infertility) is also increasing (Hudson 2009, Mascarenhas 2012). Among the most frequent medical causes of impaired reproduction are sperm defects and ovulatory disorders, and a significant number of couples worldwide encounter such problems. Female forms of infertility can be represented by anovulation, obstructed fallopian tubes, endometriosis or uterine abnormalities. In contrast, male infertility may take the form of diminished production of morphologically healthy sperm, but studies have shown that other factors such as obesity, smoking or chemical exposure may also contribute to infertility (Adamson and Baker 2003, Foster 2008).

In this study, there were significant decreases in sperm counts and marked decreases in sperm motility in all study groups compared to control. Moreover, all study groups showed increased abnormal sperm morphology vs. control. BPA+DEHP group had the highest abnormal sperm morphology and the lowest sperm motility in all of the study groups. We can suggest that prenatal exposure to EDCs, particularly combined exposures may lead to decreases in sperm count, sperm motility and sperm morphology. This may lead to an increase male infertility, as suggested by different studies in literature.

The primary reasons widely recognized for male infertility include impaired sperm production, sperm number or sperm motility (Da Silva et al. 2019; De Campos et al. 2019). However, the molecular mechanisms and pathogenesis underlying infertility remain to be determined. Yamasaki et al. (2017) identified a series of key male reproductive proteins including epididymal protease inhibitor (EPPIN), dynein axonemal heavy chain 1 (DNAH1), and semenogelin (SEMG) to be associated with male infertility.
