Objectives: A prospective, randomized controlled trial in women seeking to conceive examined the impact of using ovulation tests on self-reported levels of stress, psychological well-being, and quality of life in women with unexplained infertility. Method: The test group used a home ovulation test to detect the day of ovulation, whereas the control group were provided with a predicted day of ovulation based on the average length of menstrual cycle reported during study recruitment. Volunteers collected their first morning urine samples to evaluate biochemical levels of stress (urinary cortisol and estrone-3-glucouronide) and completed questionnaires over two complete menstrual cycles. Results: Overall, the use of digital ovulation tests by sub-fertile women under medical care had negligible negative effects and no detectable positive benefit on psychological well-being, according to multiple measurements of stress by questionnaire and biochemical markers. No significant differences were found between groups for all stress measures at the various study time points, except in relation to "couple concordance" where the test group scored much higher than the control group (mean difference at end of study was 21.25 (95% confidence interval: 9.25, 33.25; P = 0.0015)). The maximum difference in log cortisol: creatinine ratio between the test and control groups was -0.28 (95% confidence interval: -0.69, 0.13). Conclusions: These results do not support propositions that using digital ovulation tests can cause stress in women trying to conceive.

The presence of pharmaceuticals, drugs and their metabolites in the environment grows and represents an actual environmental problem, there is an increasing trend to involve new environmental technologies. We can therefore observe an increasing trend to involve new environmental technologies. Membrane technologies, advanced oxidation processes (AOPs), and their various modifications are the most frequently studied advanced technologies. There is also an effort to develop new types of drugs that are biodegradable in sewage disposal plants. The adverse effects of drugs in the environment are already reflected in the European Union legislation. Active substances, such as diclofenac, 17-alpha-ethinylestradiol and 17-beta-estradiol, estrone, erythromycin, clarithromycin and azithromycin, are included in the list of followed compounds in the water management monitoring. This screening was set up by the European Commission in 2015 to monitor and evaluate the risks posed by these compounds.
