Impairment of Oogenesis and Folliculogenesis in Neonatal Rats after Maternal Exposure to Mobile Phones

This animal study examined maternal mobile phone exposure during different gestational windows in Wistar rats and assessed ovarian development and hormones in neonatal offspring. Compared with sham (phone off), exposed groups (standby and conversation/standby) were reported to have lower neonatal estrogen and…

Effects of 700MHz radiofrequency radiation (5G lower band) on the reproductive parameters of female Wistar rats

This animal study examined short- and long-term 700 MHz (lower-band 5G) radiofrequency exposure in female Wistar rats, comparing control, sham, and exposed groups. It reports no DNA damage and no change in estrous cycle length, but increased ovarian oxidative stress markers in exposed animals. Long-term exposure was…

Electromagnetic Field (EMF) Radiation Alters Estrogen Release from the Pig Myometrium during the Peri-Implantation Period.

This ex vivo animal-tissue study tested whether ELF-EMF exposure (50 or 120 Hz for 2 or 4 hours) alters estrogenic activity in pig myometrium during the peri-implantation period. The authors report EMF-associated changes in estrogen-related gene transcripts and aromatase abundance, with progesterone diminishing some…

Extremely low-frequency electromagnetic field (EMF) generates alterations in the synthesis and secretion of oestradiol-17β (E) in uterine tissues: An in vitro study.

This in vitro study exposed porcine endometrial and myometrial slices to extremely low-frequency EMF (50 or 120 Hz, 8 mT) for 2 or 4 hours, with or without progesterone. The authors report frequency- and time-dependent changes in oestradiol-17β secretion and CYP19A3 mRNA expression, with fewer changes when…
