Purpose

To investigate the relation between mutations in ciliopathy-related SPAG6 and RSPH3 and male infertility with severe asthenoteratospermia characterized by multiple flagellar malformations and reveal the intracytoplasmic sperm injection (ICSI) outcomes of those primary ciliary dyskinesia (PCD) patients.

Methods

Whole-exome sequencing was applied to identify the pathogenic genes for the five PCD patients. The ICSI outcomes of those patients were compared with eight DNAH1-mutated patients and 215 oligo-asthenospermia (OAT) patients.

Results

We identified, for the first time, the compound heterozygous SPAG6 mutations (c.143_145del: p.48_49del, c.585delA: p.Lys196Serfs*6) in a sporadic PCD patient. Further, a novel homozygous nonsynonymous RSPH3 mutation (c.C799T: p.Arg267Cys) was identified in another PCD patient with consanguineous parents. The pathogenicity of these mutations in the assembly of sperm flagella was confirmed by flagellar ultrastructure analysis, immunofluorescence, and quantitative real-time PCR. All five patients underwent six ICSI cycles. The fertilization rate, blastocyst development rate, and clinical pregnancy rate were 69.3%, 50.0%, and 66.7%, respectively. Four of the five couples, including the subjects carrying mutations in SPAG6 or RSPH3, got healthy children born after ICSI. Additionally, the ICSI outcomes of the five PCD couples were statistically comparable with those of the eight DNAH1-mutated couples and the 215 OAT couples.

Conclusions

Mutations in ciliopathy-related SPAG6 and RSPH3 cause severe asthenoteratospermia characterized by multiple flagellar malformations, resulting in sterility. ICSI is an optimal management with a positive pregnancy outcome."xsd:string
