Spermatogenic failure 74(SPGF74)

MedGen UID:
1812069
•Concept ID:
C5677010
•
Disease or Syndrome
Synonym: SPGF74
 
Gene (location): MSH5 (6p21.33)
 
Monarch Initiative: MONDO:0030972
OMIM®: 619937

Definition

Spermatogenic failure-74 (SPGF74) is characterized by nonobstructive azoospermia and male infertility due to complete meiotic arrest at the spermatocyte zygotene or pachytene stage. Some men exhibit reduced testicular volume and/or reduced testosterone level (Wyrwoll et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Clinical features

From HPO
Male infertility
MedGen UID:
5796
•Concept ID:
C0021364
•
Disease or Syndrome
The inability of the male to effect fertilization of an ovum after a specified period of unprotected intercourse. Male sterility is permanent infertility.

Non-obstructive azoospermia
MedGen UID:
866757
•Concept ID:
C4021107
•
Disease or Syndrome
Absence of any measurable level of sperm in his semen, resulting from a defect in the production of spermatozoa in the testes. This can be differentiated from obstructive azoospermia on the basis of testicular biopsy.

Spermatogenesis maturation arrest

Finding
Maturation arrest (MA) is defined as germ cells that fail to complete maturation. Uniform MA is characterized by spermatogenic arrest at the same stage of spermatogenesis throughout the seminiferous tubules. MA is subcategorized into early MA, in which only spermatogonia or spermatocytes are found, and late MA, in which spermatids are detected without spermatozoa.
