Endometriosis is a gynecological disease related to menstruation that affects nearly 10% of reproductive-age women. However, so far, there are no reliable diagnostic biomarkers for endometriosis, causing delay in diagnosis 6.7 ± 6.2 years. Menstrual blood non-invasive source endometrial tissue can be analyzed endometriosis. In this study, menstrual samples were collected from women with (n = 8) and without Data Independent Acquisition (DIA)-based mass spectrometry bioinformatic analysis used...

Abstract The precise mechanisms behind early embryonic arrest due to sperm‐related factors and the most effective strategies are not yet fully understood. Here, we present two cases of male infertility linked novel TDRD6 variants, associated with oligoasthenoteratozoospermia (OAT) arrest. To investigate underlying promising therapeutic approaches, Tdrd6 knock‐in knock‐out mice were generated. variant demonstrated OAT arrest, mirroring clinical observations our patients.
