Many men wonder whether WiFi exposure affects their fertility. This is a valid concern—laptops, phones, and routers emit radiofrequency electromagnetic fields (RF-EMF) at 2.4 GHz, the same frequency that laboratory studies have shown can affect sperm cells.
Our analysis of peer-reviewed studies on RF-EMF and male reproductive health reveals a consistent pattern: exposure to WiFi-frequency radiation is associated with decreased sperm motility, reduced sperm count, and increased DNA fragmentation in sperm cells. These effects have been observed in both animal studies and human sperm samples exposed in laboratory conditions.
Below, we present the research evidence organized by effect type and study quality, so you can understand what science actually shows about WiFi and male fertility.
Margaritis LH et al. · 2014
Researchers exposed fruit flies to common wireless devices like cell phones, WiFi, and Bluetooth to study reproductive effects. All devices significantly reduced egg production and increased cell death, even at very low exposure levels below current safety guidelines, suggesting potential biological impacts.

Researchers exposed male mice to cell phone-level radiation (1800 MHz) for two hours daily over 32 days. The radiation reduced sperm count and testosterone while increasing estradiol and disrupting natural daily hormone rhythms, suggesting potential male fertility risks from cell phone use.
Shahin S, Mishra V, Singh SP, Chaturvedi CM. · 2014
Researchers exposed male mice to 2.45 GHz microwave radiation (the same frequency used by Wi-Fi routers and microwave ovens) for 2 hours daily over 30 days at very low power levels. The exposed mice showed significant decreases in sperm count and viability, along with damaged sperm-producing tissue and reduced testosterone levels. This suggests that chronic exposure to common wireless frequencies may impair male fertility through oxidative stress mechanisms.

Researchers exposed male rats to Wi-Fi frequency radiation (2.45 GHz) for 2 hours daily over 45 days, finding it damaged sperm DNA and caused oxidative stress in testicular tissue. The antioxidant melatonin prevented this damage, suggesting everyday microwave radiation may harm male fertility but antioxidants could provide protection.
Vijver MG et al. · 2013
Dutch researchers exposed four species of small invertebrates (insects and other small creatures) to radiofrequency radiation from mobile phone base stations for 48 hours to see if it affected their ability to reproduce. They found no significant impact on fertility or offspring production. However, the researchers emphasized that finding no effects doesn't rule out potential harm, since scientists still don't fully understand how non-thermal EMF exposure might affect living organisms.
Tumkaya L, Kalkan Y, Bas O, Yilmaz A. · 2013
Turkish researchers exposed young male rats to mobile phone radiation for one hour daily during their pubertal development (45 days total) and found no damage to testicular tissue structure or sperm-producing cells. The study examined tissue samples under microscopes using multiple staining techniques to detect any cellular abnormalities or signs of cell death. This suggests that mobile phone radiation at low absorption rates may not harm male reproductive development during puberty.
Trošić I, Mataušić-Pišl M, Pavičić I, Marjanović AM. · 2013
Researchers exposed male rats to 915 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily over two weeks to study effects on reproductive health. They found no significant changes in testicular structure, sperm count, sperm mobility, or sperm appearance compared to unexposed rats. The study suggests that short-term intermittent RF exposure at these levels may not pose immediate risks to male reproductive function.
Rago R et al. · 2013
Italian researchers studied 63 men to see how cell phone use affects sperm quality, dividing them into groups based on daily usage from none to over 4 hours. While most sperm measurements stayed normal, men using phones more than 4 hours daily showed significantly more DNA damage in their sperm, with the worst effects in those who kept phones in their pants pockets. This suggests that heavy cell phone use, especially when carried close to reproductive organs, may harm sperm DNA integrity.
Poulletier de Gannes F et al. · 2013
French researchers exposed rats to Wi-Fi signals (2.45 GHz) for one hour daily during sexual maturation, mating, and pregnancy to test effects on fertility and fetal development. The study found no harmful effects on reproductive organs, fertility rates, or fetal abnormalities, even at high exposure levels of 4 watts per kilogram. This suggests Wi-Fi exposure at these levels may not significantly impact reproductive health in rats.
Akdag MZ et al. · 2013
Researchers exposed rats to 50 Hz magnetic fields (the same frequency as power lines) for 10 months to test effects on sperm health, cell death, and oxidative stress. They found no impact on sperm count or quality, and no oxidative damage at either exposure level tested. However, higher exposure (500 μT) did increase markers of programmed cell death in testicular tissue.
Nazıroğlu M, Yüksel M, Köse SA, Özkaya MO · 2013
This review examined research on how Wi-Fi and cell phone radiation affects reproductive health in both men and women. The researchers found that while EMF exposure doesn't appear to directly cause infertility, it does trigger oxidative stress (cellular damage from harmful molecules) and can harm reproductive organs in animal studies. In male animals, radiation exposure damaged sperm-producing tissues and reduced testosterone, while in females it caused inflammation and reduced egg follicles.
Mortazavi S et al. · 2013
Iranian researchers exposed sperm samples from 30 healthy men to radiofrequency radiation from mobile phone jammers (devices that block cell signals) for 2-4 hours. The sperm exposed to jammer radiation showed significantly reduced motility (ability to swim) compared to unexposed samples. This suggests that mobile jammers, commonly used in some countries to block cell phone signals in public spaces, could impair male fertility.
Kesari KK, Kumar S, Nirala J, Siddiqui MH, Behari J. · 2013
This review examined how radiofrequency radiation from mobile phones affects male reproductive health, particularly when phones are carried in pockets near reproductive organs. The researchers found that mobile phone radiation increases harmful reactive oxygen species (molecules that damage cells) in testicular tissue, leading to decreased sperm count, DNA damage, and hormonal changes that can cause infertility. The study highlights the biological mechanisms by which everyday mobile phone use may be compromising men's fertility through oxidative stress and cellular damage.
Ghanbari M, Mortazavi SB, Khavanin A, Khazaei M. · 2013
Researchers exposed male rats to cell phone radiation at 900 MHz (the frequency used by GSM networks) for 2-3 weeks and measured effects on sperm health. They found that exposed rats had significantly reduced sperm viability, motility, and antioxidant defenses compared to unexposed controls. Longer exposure periods caused even greater damage to sperm quality.
Ghanbari M1, Mortazavi SB1, Khavanin A1, Khazaei M2. · 2013
Researchers exposed male rats to cell phone radiation at 900 MHz (the frequency used by GSM networks) for two to three weeks and measured effects on sperm quality. They found that exposure significantly reduced sperm viability, motility (swimming ability), and antioxidant defenses compared to unexposed rats, with longer exposure causing greater damage. This suggests cell phone radiation may impair male fertility by creating oxidative stress in reproductive cells.
Li SS, Zhang ZY, Yang CJ, Lian HY, Cai P · 2013
Researchers exposed fruit flies (Drosophila) to extremely low frequency electromagnetic fields and found significant changes in gene expression affecting reproduction, aging, and cellular stress responses. Short-term exposure reduced male reproductive ability and altered expression of over 1,300 genes, while long-term exposure changed expression of more than 1,700 genes. The study suggests EMF exposure may accelerate cellular aging and compromise reproductive function through effects on sperm development.
Luo Q, Jiang Y, Jin M, Xu J, Huang HF. · 2013
Researchers exposed pregnant women (about 50 days pregnant) to cell phone radiation for one hour and then analyzed protein changes in their placental tissue. They found significant alterations in 15 different proteins, including those involved in cell growth and nervous system development. This suggests that cell phone radiation may affect early embryonic development during the most vulnerable stage of pregnancy.
Mild KH, Andersen JB, Pedersen GF. · 2012
Researchers examined whether mobile phones in standby mode produce meaningful EMF exposure, after several studies claimed standby phones could affect sleep and reproductive health. They found that phones in standby mode only transmit briefly every 2-5 hours for location updates, functioning as passive receivers the rest of the time with essentially no microwave emissions. This means EMF exposure from phones in standby mode is negligible.
Ozlem Nisbet H, Nisbet C, Akar A, Cevik M, Karayigit MO · 2012
Turkish researchers exposed young male rats to cell phone frequencies (900 MHz and 1800 MHz) for 2 hours daily over 90 days to study effects on reproductive development. They found that EMF exposure increased testosterone levels and accelerated sperm development compared to unexposed rats. The researchers concluded this electromagnetic exposure may trigger early puberty in developing males.
Mouradi R, Desai N, Erdemir A, Agarwal A · 2012
Researchers developed a computer model to figure out how far apart cell phones and sperm samples should be in laboratory experiments to accurately mimic real-world conditions, like when a phone is carried in a pants pocket. They found that lab experiments need to place phones 0.8 to 1.8 centimeters farther from sperm samples than the actual distance between a phone and testicles in the body. This research helps ensure that laboratory studies on cell phone radiation and sperm health reflect what actually happens when men carry phones near their reproductive organs.
Kesari KK, Behari J. · 2012
Researchers exposed male rats to mobile phone radiation for 2 hours daily over 45 days and found significant damage to their reproductive health. The exposed rats had lower testosterone levels, damaged sperm structure, and produced fewer offspring that weighed less than normal. The scientists believe this damage occurs because the radiation triggers harmful reactive oxygen species (free radicals) that attack reproductive cells.
Baste V, Moen BE, Oftedal G, Strand LA, Bjørge L, Mild KH. · 2012
Norwegian researchers tracked nearly 38,000 pregnancies from navy servicemen to see if fathers' radiofrequency exposure affected pregnancy outcomes. They found that when fathers worked on fast patrol boats (which emit high RF radiation) during the three months before conception, their partners had higher rates of preeclampsia (dangerous pregnancy complication) and perinatal death. The timing mattered - only exposure during sperm development showed these effects.
Avendaño C, Mata A, Sanchez Sarmiento CA, Doncel GF. · 2012
Researchers exposed sperm samples from 29 healthy men to WiFi-connected laptops for 4 hours and found significant damage compared to unexposed samples. The WiFi exposure reduced sperm's ability to swim properly and caused DNA fragmentation (genetic damage) without generating heat. This suggests that men who regularly use WiFi laptops on their laps may be harming their fertility.
Al-Damegh MA. · 2012
Researchers exposed rats to electromagnetic radiation from cell phones for 15-60 minutes daily over two weeks and found significant damage to testicular tissue and sperm production. The radiation caused a 3-fold increase in harmful oxidative stress markers while dramatically reducing protective antioxidant levels by 3-5 fold. However, supplementing with vitamins C and E helped protect against this reproductive damage.
Kesari KK, Behari J. · 2012
Researchers exposed male rats to mobile phone radiation for 2 hours daily over 45 days and found significant damage to their reproductive health. The exposed rats had lower testosterone levels, damaged sperm cells, and fewer offspring that weighed less than normal. The study suggests this damage occurs through oxidative stress (cellular damage from unstable molecules called free radicals).
