The increase in frozen embryo transfers is a consequence of advances in embryo vitrification and the implementation of genetic screening of embryos. There is debate over the best progesterone administration route in substituted cycles and the relationship between progesterone levels on embryo transfer day and reproductive outcomes. This trial aimed to compare the clinical results of different progesterone supplementation schedules before embryo transfer and assess the relationship between plasmatic progesterone levels on transfer day and clinical outcomes.

However, following their application to soils, these adsorbents undergo changes in their physicochemical properties over time due to their interaction with soil components. In this study, the adsorption capacity of a commercial biochar and a commercial organoclay for the antibiotic sulfamethoxazole (SFMX) and the pesticide ethofumesate (ETFM) was evaluated over aging periods of 3 months in the laboratory and 1 year in the field, subsequent to their application to a Mediterranean soil.

In plasma, they could also be biomarkers of synovial pathology. The aim of this study is to determine if synovial oxylipins in inflamed joints correlate with plasma oxylipins and with synovial histologic patterns.

Summary Answer: The injection of PRP increases the number of retrieved oocytes without increasing the quality of developed blastocysts.
What Is Known Already: Management of women with reduced ovarian response to stimulation is one of the significant challenges in reproductive medicine. Recently, PRP treatment has been proposed as an adjunct in assisted reproduction technology, with controversial results.
