Conditions with this feature

Spermatogenic failure 16
MedGen UID:
934641
Concept ID:
C4310674
Disease or Syndrome
Spermatogenic failure-16 (SPGF16) is characterized by acephalic spermatozoa causing male infertility. Semen from affected men consistently shows nearly 100% abnormally shaped spermatozoa, mostly made up of headless tails, with a small proportion of intact spermatozoa with an abnormal head-tail junction, as well as a few tailless heads. Ultrastructurally, the anomaly involves absence of the implantation fossa and basal plate between the sperm head and the tail (summary by Zhu et al., 2016). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).
Spermatogenic failure 21
MedGen UID:
1617056
Concept ID:
C4539991
Disease or Syndrome
Spermatogenic failure-21 (SPGF21) is characterized by acephalic spermatozoa causing male infertility (Li et al., 2017). For a general phenotypic description and a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).
Spermatogenic failure 26
MedGen UID:
1644751
Concept ID:
C4693773
Disease or Syndrome
Spermatogenic failure-26 (SPGF26) is characterized by acephalic spermatozoa due to breakage that occurs in the midpiece of the sperm (Sha et al., 2018). For a general phenotypic description and discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).
Spermatogenic failure 31
MedGen UID:
1648419
Concept ID:
C4748234
Disease or Syndrome
SPGF31 is characterized by male infertility due to oligozoospermia with a high proportion (greater than 90%) of acephalic sperm. Affected couples may overcome infertility with intracytoplasmic sperm injection (Zhu et al., 2018). For a discussion of phenotypic and genetic heterogeneity of spermatogenic failure, see 258150.
Spermatogenic failure 44
MedGen UID:
1750188
Concept ID:
C5436678
Disease or Syndrome
Spermatogenic failure-44 (SPGF44) is characterized by male infertility due to headless sperm in the ejaculate (Sha et al., 2020). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).
