It has been shown that ROS1, a receptor tyrosine kinase expressed in the epididymis, is essential for epididymal differentiation, sperm maturation, and male fertility in mice. However, it is unknown if inhibition of ROS1 suppresses male fertility reversibly.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>Our study aimed to investigate the effects of ROS1 inhibitor administration in male mice on sperm function and fertility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>We used lorlatinib, an anti\u2010cancer drug that inhibits ROS1. We treated 10\u2010week\u2010old sexually mature male mice with lorlatinib for 3\u00a0weeks and performed fertility tests, histological staining, in vitro fertilization, sperm motility analyses, and immunoblot analyses. We also performed the same analyses 3\u00a0weeks after discontinuing the lorlatinib treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Inhibition of ROS1 for 3\u00a0weeks suppressed male fertility. Lorlatinib\u2010treated mice showed no overt abnormalities in testicular sections, but epithelium maintenance of the epididymal initial segment was impaired. Accordingly, the levels of OVCH2, RNASE10, and ADAM28, which are expressed in the epididymis, decreased. Spermatozoa from the lorlatinib\u2010treated mice lost their ability to bind to the zona pellucida, and ADAM3 processing was abnormal. Sperm motility was also impaired in the lorlatinib\u2010treated mice. These impairments were recovered 3\u00a0weeks after discontinuing the drug treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion and conclusion<\/jats:title>\n                    <jats:p>Inhibition of ROS1 with lorlatinib suppressed sperm maturation and male fertility reversibly.
