The Role of Long Noncoding RNAs on Male Infertility: A Systematic Review and In Silico Analysis

open access: yesBiology, 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.

Expression of Apoptosis-Related Genes in Cat Testicular Tissue in Relation to Sperm Morphology and Seasonality—A Preliminary Study

open access: yesAnimals, 2021
Apoptosis is a crucial process in spermatogenesis, responsible for the elimination of abnormal sperm cells and testicular regression out of breeding season.

Analysis of PRM1 and PRM2 Polymorphisms in Iranian Infertile Men with Idiopathic Teratozoospermia [PDF]

open access: yesInternational 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]

open access: yesInternational 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.

Aneuploidy in spermatozoa of infertile men with teratozoospermia [PDF]

open access: yesInternational Journal of Andrology, 2001
Recent studies have shown that aneuploidy in spermatozoa of infertile men with poor semen quality is increased. The purpose of this study was to determine whether poor sperm morphology is associated with the incidence of spermatozoa with numerical chromosome abnormalities.

Effect of the oral intake of astaxanthin on semen parameters in patients with oligo-astheno-teratozoospermia: a randomized double-blind placebo-controlled trial [PDF]

open access: yes, 2020
Higher concentrations of seminal reactive oxygen species may be related to male infertility. Astaxanthin with high antioxidant activity can have an impact on the prevention and treatment of various health conditions, including cancer.

ACTN4 Mediates SEPT14 Mutation-Induced Sperm Head Defects

open access: yesBiomedicines, 2020
Septins (SEPTs) are highly conserved GTP-binding proteins and the fourth component of the cytoskeleton. Polymerized SEPTs participate in the modulation of various cellular processes, such as cytokinesis, cell polarity, and membrane dynamics, through ...

Sperm DNA Integrity in Absolute Teratozoospermia Patients and its Impact on Assisted Reproductive Technology Outcome [PDF]

open access: yes, 2023
Sperm DNA Fragmentation (SDF) is a common cause of male infertility, although it is underdiagnosed due to lack of routine testing. High levels of SDF are reported in men with abnormal sperm morphology.

Genetic aspects of monomorphic teratozoospermia: a review [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2015
Teratozoospermia is characterized by the presence of spermatozoa with abnormal morphology over 85 % in sperm. When all the spermatozoa display a unique abnormality, teratozoospermia is said to be monomorphic. Two forms of monomorphic teratozoospermia, representing less than 1 % of male infertility, are recognized: macrozoospermia (also called ...
