The aim of the study was to examine the association between modifiable lifestyle factors and main semen parameters, sperm morphology, and sperm chromatin structure. The study population consisted of 344 men who were attending an infertility clinic for diagnostic purposes with normal semen concentration of 20-300 M/ml or with slight oligozoospermia (semen total concentration of 15-20 M/ml) [WHO 1999]. Participants were interviewed and provided semen samples. The interview included questions about demographics, socio-economic status, medical history, lifestyle factors (consumption of alcohol, tobacco, coffee intake, cell phone and sauna usage), and physical activity. The results of the study suggest that lifestyle factors may affect semen quality. A negative association was found between increased body mass index (

Exposure to ambient air pollution-does it affect semen quality and the level of reproductive hormones?

“…Full details of the parent study have been described elsewhere (Jurewicz et al, 2014). The Nofer Institute of Occupational Medicine Bioethical Committee Board approved the study (Resolution No 9/2007(04.06.2007) and written informed consent was obtained from all subjects before their participation.…”

The association between environmental exposure to pyrethroids and sperm aneuploidy

“…All participants completed questionnaire which collected demographic information, lifestyle factors and medical history. Full details of the parent study have been described elsewhere (Jurewicz et al, 2014). Study participants provided urine, saliva and semen samples on the same day.…”

“…The volume, pH, color, and viscosity were determined for each sample. Measurement of the semen parameters has been previously described (Jurewicz et al, 2014). The sexual abstinence before the semen analysis last mostly 3-7 d (71%).…”

Effects of occupational exposure - is there a link between exposure based on an occupational questionnaire and semen quality?

“…Smoking status was verified by measurement of cotinine level in saliva using high performance liquid chromatography coupled with tandem mass spectrometry/positive electrospray ionization (LC-ESI + MS/MS) and isotope dilution method. A detailed description of this study population has been presented elsewhere [Jurewicz et al 2013a;Jurewicz et al 2014]. The work during the time of questionnaire was declared by 336 (98% of original study sample) and the association between occupational factors and semen quality was studied in this group of men.…”
