Previously we identified a pathogenic variant in the dynein gene\n                  <jats:italic>AXDND1<\/jats:italic>\n                  in an infertile man.

Subsequently, a progressive imbalance of spermatogonial commitment to spermatogenesis over self-renewal occurred, ultimately leading to catastrophic germ cell loss, loss of blood-testis barrier patency and immune cell infiltration. Sperm produced during the first wave of spermatogenesis were immotile due to abnormal axoneme structure, including the presence of ectopic vesicles and abnormalities in outer dense fibres and microtubule doublet structures. Sperm output was additionally compromised by a severe spermiation defect and abnormal sperm individualisation. Collectively, our data highlight the essential roles of AXDND1 as a regulator of spermatogonial commitment to spermatogenesis and during the processes of spermiogenesis where it is essential for sperm tail development, release and motility.\n                <\/jats:p>","DOI":"10.1101\/2023.11.02.565050","type":"posted-content","created":{"date-parts":[[2023,11,4]],"date-time":"2023-11-04T23:55:14Z","timestamp":1699142114000},"source":"Crossref","is-referenced-by-count":2,"title":["AXDND1 is required to balance spermatogonial commitment and for sperm tail formation in mice and humans"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1078-756X","authenticated-orcid":false,"given":"Brendan J.","family":"Houston","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
