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

On several occasions during the 20th c. archaeological finds were brought to light at Gaarz. A great part of the finds from this site in Ostholstein (Germany) hints at a Slavic settlement there. During surveys with the metal detector from the year 2012 onwards, a steadily growing mass of metal finds was uncovered. Some of these are of high quality and attest to wealth which exceeds the scope of merely rural settlements. In this paper some of the archaeological material is presented and the function of this “new” site in the vicinity of the central place of Starigard/Oldenburg is discussed
