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 ...

Body mass index and age correlate with antioxidant supplementation effects on sperm quality: Post hoc analyses from a double-blind placebo-controlled trial [PDF]
, 2020 Spermatozoa are vulnerable to lack of energy and oxidative stress as a result of elevated levels of reactive oxygen species. Therefore, it is essential that appropriate nutrients are available during maturation.

Genetics of teratozoospermia: Back to the head [PDF]
Best Practice & Research Clinical Endocrinology & Metabolism, 2020 Spermatozoa are polarized cells with a head and a flagellum joined by the connecting piece. Head integrity is critical for normal sperm function, and head defects consistently lead to male infertility. Abnormalities of the sperm head are among the most severe and characteristic sperm defects.

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.

Association between Sperm Morphology and Altered Sperm microRNA Expression
Biology, 2022 Evaluation of male infertility has been based on semen analysis for years. As this method can be subjective at times, there is a scientific tendency to discover stable and quantifiable biomarkers.
