Asian Journal of Andrology, 2021 Sperm morphology was once believed as one of the most predictive indicators of pregnancy outcome in assisted reproductive technology (ART). However, the impact of teratozoospermia on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI ...

Is sperm telomere length altered in teratozoospermia specimens? A case-control study
International Journal of Reproductive BioMedicine, 2022 Background: Male factor infertility is a multifactorial defect, and many of its etiologies are unknown. Teratozoospermia is determined by the existence of over 85% morphologically abnormal spermatozoa in semen which are almost incompetent in ...

Localization Patterns of RAB3C Are Associated with Murine and Human Sperm Formation
Medicina, 2022 Background and Objectives: Septins (SEPTs) are highly conserved GTP-binding proteins and the fourth component of the cytoskeleton. Polymerization of SEPTs contributes to several critical cellular processes such as cytokinesis, cytoskeletal remodeling ...

Pathogenic Variants in ACTRT1 Cause Acephalic Spermatozoa Syndrome
Frontiers in Cell and Developmental Biology, 2021 Acephalic spermatozoa syndrome is a rare type of teratozoospermia, but its pathogenesis is largely unknown. Here, we performed whole-exome sequencing for 34 patients with acephalic spermatozoa syndrome and identified pathogenic variants in the X-linked ...

miR-508-5p and mir-510-5p expressions and their relationships with spermatozoa motility and morphology [PDF]
Journal of Shahrekord University of Medical Sciences, 2020 Background and aims:miRNAs have regulatory functions in developmental processes. The stages of spermatogenesis can also be affected by miRNAs. We tried to detect a relationship between the expression of miR-508-5p and miR-510-5p and male infertility. The

The Role of Long Noncoding RNAs on Male Infertility: A Systematic Review and In Silico Analysis
Biology, 2022 Male infertility is a complex disorder affecting many couples worldwide. Long noncoding RNAs (lncRNAs) regulate important cellular processes; however, a comprehensive understanding of their role in male infertility is limited.

Analysis of PRM1 and PRM2 Polymorphisms in Iranian Infertile Men with Idiopathic Teratozoospermia [PDF]
International Journal of Fertility and Sterility, 2019 Single nucleotide polymorphisms (SNPs) in a number of genes involved in sperm maturation are considered as one of the main factors for male infertility.

Assisted Oocyte Activation following Intracytoplasmic Sperm Injection: A Sensible Option for Infertile Couples with Severe Teratozoospermia [PDF]
International Journal of Fertility and Sterility, 2023 The intracytoplasmic sperm injection (ICSI) has significantly improved male factor infertility treatment; however, complete fertilization failure still occurs in 1-5% of ICSI treatment cycles mainly due to oocyte activation failure.
