Abstract
BACKGROUND
Acephalic spermatozoa syndrome (ASS) is an extremely rare form of severe teratozoospermia, where in most of the sperm either appear to lack heads or have disconnected or poorly connected heads and tails.
CASE SUMMARY
We reported the case of a male patient with secondary infertility whose sperm showed typical ASS upon morphological analysis. Whole-exome sequencing was performed on the patient’s peripheral blood, which revealed two heterozygous variants of the PMFBP1 gene: PMFBP1c.414+1G>T (p.?) and PMFBP1c.393del (p.C132Afs*3).
CONCLUSION
It is speculated that the compound homozygous mutation of PMFBP1 may be the cause of ASS. We conducted a literature review in order to provide the basis for genetic counseling and clinical diagnosis of patients with ASS.
Core Tip: Acephalic spermatozoa syndrome (ASS) is an extremely rare form of teratozoospermia. Patients with ASS are often unable to conceive naturally, and intracytoplasmic sperm injection is the main method used for such patients to produce biological offspring. Recent studies have shown that ASS is associated with inherited genetic mutations.
