Spermatogenic failure 18

Spermatogenic failure-18 is a form of male infertility caused by multiple morphologic abnormalities of the sperm flagella (Ben Khelifa et al., 2014). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Spermatogenic failure 46

Spermatogenic failure-46 (SPGF46) is characterized by male infertility due to asthenoteratozoospermia. Sperm of affected men exhibit multiple morphologic abnormalities of the flagella (MMAF), including flagella that are absent, short, coiled, angulated, and/or of irregular caliber. Ultrastructural analysis shows disorganization of axonemal and periaxonemal structures (Liu et al., 2020). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Spermatogenic failure 27

Spermatogenic failure-27 (SPGF27) is characterized by infertility due to multiple morphologic abnormalities of the sperm flagella (MMAF), a phenotype also designated as 'dysplasia of the fibrous sheath,' 'short tails,' or 'stump tails.' Spermatozoa in the ejaculate exhibit short, irregular, coiled, or absent flagella. Ultrastructural analysis shows loss of the central pair of microtubules, loss of the inner dynein arms, and peripheral doublet disorganization (Lores et al., 2018). For a discussion of the phenotypic and genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Spermatogenic failure 39

Spermatogenic failure-39 (SPGF39) is characterized by infertility due to asthenozoospermia. In some patients, spermatozoa exhibit multiple morphologic anomalies of the sperm flagellum (MMAF), including short, absent, irregularly shaped, and coiled flagella. Abnormalities of the sperm head and midpiece have also been observed, and ultrastructural analysis shows a lack of the outer dynein arms (ODAs) in sperm cells. In other patients, sperm do not exhibit MMAF, and ultrastructural analysis shows that many flagella lack 1 or more of microtubule doublets (MTDs) 4 to 7 at the principal piece or end piece; however, ODAs are present at the remaining MTDs (Whitfield et al., 2019; Zhang et al., 2020).

Spermatogenic failure-24 (SPGF24) is characterized by multiple morphologic abnormalities of the flagella (MMAF), including absent, short, coiled, bent, and irregular-caliber flagella. Malformations of the sperm head have also been observed. In addition, patients exhibit very low sperm concentrations and total sperm counts per ejaculate (Dong et al., 2018).

Spermatogenic failure 42

Spermatogenic failure-42 (SPGF42) is characterized by infertility and spermatozoa with almost no progressive motility due to multiple morphologic abnormalities of the flagella (MMAF), including short, absent, coiled, irregular-caliber, and/or bent flagella. Some spermatozoa also show abnormalities of the head, acrosome, midpiece, or endpiece (Lores et al., 2019; Liu et al., 2019).

Spermatogenic failure 37

Spermatogenic failure-37 (SPGF37) is characterized by primary male infertility with asthenoteratozoospermia. Spermatozoa exhibit severely reduced motility due to multiple morphologic abnormalities of the flagella (MMAF), primarily consisting of short or absent flagella. Neck defects at the head-tail junction are frequently seen (Liu et al., 2019).
