Detrimental impact of cell phone radiation on sperm DNA integrity

Abstract

Detrimental impact of cell phone radiation on sperm DNA integrity Koohestanidehaghi Y, Khalili MA, Dehghanpour F, Seify M. Detrimental impact of cell phone radiation on sperm DNA integrity. Clinical and Experimental Reproductive Medicine 2024;51(1):13-19. Abstract Radiofrequency electromagnetic radiation (RF-EMR) from various sources may impact health due to the generation of frequency bands. Broad pulses emitted within frequency bands can be absorbed by cells, influencing their function. Numerous laboratory studies have demonstrated that mobile phones— generally the most widely used devices—can have harmful effects on sex cells, such as sperm and oocytes, by producing RF-EMR. Moreover, some research has indicated that RF-EMR generated by mobile phones can influence sperm parameters, including motility, morphology, viability, and (most critically) DNA structure. Consequently, RF-EMR can disrupt both sperm function and fertilization. However, other studies have reported that exposure of spermatozoa to RF-EMR does not affect the functional parameters or genetic structure of sperm. These conflicting results likely stem from differences among studies in the duration and exposure distance, as well as the species of animal used. This report was undertaken to review the existing research discussing the effects of RF-EMR on the DNA integrity of mammalian spermatozoa. Conclusion EMW can induce oxidative stress, which subsequently leads to disorders such as reduced mobility, morphological changes, acrosome disturbances, and ultimately, damage to the nucleus and genetic material. This oxidative damage to DNA can result in the breakdown of both single-stranded and double- stranded DNA structures, culminating in fragmentation. If the DNA is not repaired and the damage accumulates, the sperm may undergo apoptosis. Damage to the sperm genome can ultimately impact fertility, potentially leading to infertility. Therefore, it is advisable to limit daily exposure to these sources to prevent irreversible damage caused by EMWs. Many men carry their cell phones in their trouser pockets or clipped to their belts, and the use of Bluetooth can increase their susceptibility to RF- EMR exposure. This exposure can induce changes in sperm quality through oxidative stress, potentially leading to infertility. Agarwal et al. [11] suggested that carrying a cell phone in a pocket could lead to a decline in sperm quality. However, it is important to note that the phone and male reproductive organs are separated by multiple tissue layers. Therefore, extrapolating these in vitro effects to real-life conditions requires further studies [11]. In July 2021, the European Parliament commissioned a research report titled “Health impact of 5G.” The report concluded that the commonly used RF-EMFs are likely carcinogenic to humans and have a definitive impact on male fertility. It also suggested potential adverse effects on the development of embryos, fetuses, and newborns. To mitigate these adverse effects, the organization proposed several strategies. These include favoring non-wireless connections, increasing distance from the source of RF- EMFs, switching off devices when not in use, and practicing safe phone usage [55].

Main findings

This narrative review summarizes existing research on RF-EMR from mobile phones and mammalian sperm DNA integrity. It reports that many laboratory studies describe harmful effects (including oxidative stress and DNA damage/fragmentation), while other studies report no effects on sperm functional parameters or genetic structure; the review attributes conflicting findings to differences in exposure duration, distance, and animal species.

Outcomes measured

• sperm DNA integrity
• sperm DNA fragmentation
• sperm motility
• sperm morphology
• sperm viability
• oxidative stress
• acrosome disturbances
• apoptosis
• fertility/infertility

Limitations

• Review describes conflicting findings across studies
• Exposure parameters (e.g., duration, distance) vary across included studies
• Notes that extrapolating in vitro effects to real-life conditions requires further studies
