Whole-exome sequencing (WES) was employed to screen a cohort of 92 MMAF patients, with candidate variants validated via Sanger sequencing and third-generation sequencing. We identified one homozygous variant in a proband from a consanguineous family and two pairs of compound heterozygous variants in two unrelated, non-consanguineous families. Routine semen analysis demonstrated markedly reduced motility across all probands. Detailed morphological and ultrastructural assessments using Papanicolaou staining, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) demonstrated that approximately 80.0% of spermatozoa exhibited pathological elongation of the mitochondrial sheath in the midpiece. Furthermore, 50.0%-70.0% of spermatozoa displayed fibrous sheath dysplasia or loss in the principal piece. Immunofluorescence assays and Western blotting confirmed that FSIP2 protein localization was disrupted, and the expression of key axonemal assembly factors was dysregulated. Notably, successful pregnancies were achieved via ICSI in the partners of two probands. This study expands the mutational spectrum of FSIP2 in both consanguineous and non-consanguineous populations.

Preliminary clinical studies demonstrate that LIPUS is beneficial for ED with varying degrees of severity, and its therapeutic effect can be enhanced when combined with phosphodiesterase 5 inhibitors. Basic researches have shown that LIPUS can treat ED resulting from type 1 diabetes mellitus, cavernous nerve injury, or cavernosa injury. The underlying mechanisms involve upregulating endothelial and neuronal nitric oxide synthase expression, increasing smooth muscle and endothelium content, inhibiting cavernosal fibrosis mediated by the transforming growth factor-β1/drosophila mothers against decapentaplegic protein/connective tissue growth factor (TGF-β1/Smad/CTGF) pathway, and ameliorating oxidative stress via microtubule-associated protein 1 light chain 3 (LC3)- and Parkin-dependent mitophagy in type 1 diabetic ED. Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ), activated by LIPUS, contribute to the recovery of neurogenic ED. Furthermore, the survival and secretion function of Schwann cells are improved by LIPUS through activating tropomyosin receptor kinase B/protein kinase B/cyclic adenosine monophosphate-response element-binding protein (TrkB/Akt/CREB) pathway, thereby accelerating cavernous nerve repair.
