18 Jun 2020 --- Spain-based Biosearch Life has applied for a patent for a probiotic strain to address infertility problems in women. The biotechnology company says this would become the first probiotic-based product for this treatment and would tap into a major and rapidly growing market. Prior research into oral administration of the CECT5713 strain of Lactobacillus salivarius found that it allowed pregnancies to be 66 percent effective in women with infertility of unknown cause. There was also reproductive success of 56 percent in women with recurrent pregnancy loss.
