RESUMO

OBJECTIVES: Abnormalities in the timing and course of spermatozoa capacitation and hyperactivation underlie common pathologies related to male infertility. Recent data shows that low frequency electromagnetic waves may influence cell membrane potential and permeability. It is therefore possible that low frequency electromagnetic waves could affect the maturation and motility processes of spermatozoa. The 43-kHz wave generator was used for modeling the impact of environmental exposure to low frequency electromagnetic radiation on human sperm. MATERIAL AND METHODS: Sperm samples were gathered from 103 fertile, healthy men aged 25-30 years old and performed computer-assisted sperm analysis. After initial examination, each participant's semen sample was divided into 2 aliquots (control and experimental) and placed in separate automated incubators. The samples constituting the experimental group were placed into the exposure system that emitted 43-kHz electromagnetic waves. Sperm motility was assessed at 3 h, 12 h and 24 h. RESULTS: Exposure to a 43-kHz radio frequency increased the percentage of sperm in progressive motility by up to 5.8% and the velocity of said sperm by up to 2 µm/s. Moreover, the total number of hyperactivated spermatozoa was significantly increased in the semen exposed to the electromagnetic signal. CONCLUSIONS: In vivo environmental exposure to 43-kHz waves may promote the development of infertility related to premature capacitation outside of the vaginal tract. Exposing semen to this particular frequency may also boost the capacitation and hyperactivation of spermatozoa in vitro, prior to conducting assisted reproductive therapies.Int J Occup Med Environ Health 2018;31(6):723-739.

RESUMO

Electromagnetic radiation (EMR) emitting from the natural environment, as well as from the use of industrial and everyday appliances, constantly influence the human body. The effect of this type of energy on living tissues may exert various effects on their functioning, although the mechanisms conditioning this phenomenon have not been fully explained. It may be expected that the interactions between electromagnetic radiation and the living organism would depend on the amount and parameters of the transmitted energy and type of tissue exposed. Electromagnetic waves exert an influence on human reproduction by affecting the male and female reproductive systems, the developing embryo, and subsequently, the foetus. Knowledge concerning this problem is still being expanded; however, all the conditionings of human reproduction still remain unknown. The study presents the current state of knowledge concerning the problem, based on the latest scientific reports.
