Spermatogenic failure-2 (SPGF2) is characterized by male infertility due to azoospermia (Tang et al., 2020; Akbari et al., 2021).
For a discussion of phenotypic and genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).

Spermatogenic failure-44 (SPGF44) is characterized by male infertility due to headless sperm in the ejaculate (Sha et al., 2020).

- Disease or Syndrome
Spermatogenic failure-77 (SPGF77) is characterized by male infertility due to extreme oligozoospermia or azoospermia. Nearly all spermatozoa present on semen analysis are morphologically abnormal, with amorphous, enlarged, and/or fragmented heads, and some are multiflagellated. Testicular tissue shows arrest at the round spermatid stage (Wyrwoll et al., 2022).
For a general phenotypic description and a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).
