Di (2-ethylhexyl) phthalate reduces sperm motility by decreasing sperm tail energy supply

Ecotoxicology and Environmental Safety
Di (2-ethylhexyl) phthalate (DEHP) is widespread in the environment. It can impair sperm function through damaging the sperm development process. However, few studies have focused on the sperm tail that is directly related to sperm motility.

Genetic mutation of Cep76 results in male infertility due to abnormal sperm tail composition [PDF]

Life Science Alliance
This study explores the role of CEP76 in male fertility via its predicted role in establishing a functional transition zone that mediates protein entry into the sperm tail.

Selenium mitigates cyclophosphamide-induced toxicity on sperm quality in mice: An experimental study [PDF]

International Journal of Reproductive BioMedicine
Background: Cyclophosphamide (CP), a commonly used chemotherapy drug, induces oxidative stress and damages testicular tissue, leading to impaired spermatogenesis.

#35 : Tail-First Sperm Injection Significantly Improved the Fertilization Rates More Than the Head-First Sperm Injection Regardless of the Elasticity of the Oocyte Membrane Following Piezo-ICSI

Fertility & Reproduction, 2023
Background and Aims: Little information is available for investigating the effect of the direction of sperm injected into the cytoplasm on clinical results for human oocytes following intracytoplasmic sperm injection (ICSI).

RAB-like 2 has an essential role in male fertility, sperm intra-flagellar transport, and tail assembly. [PDF]

PLoS Genetics, 2012
A significant percentage of young men are infertile and, for the majority, the underlying cause remains unknown. Male infertility is, however, frequently associated with defective sperm motility, wherein the sperm tail is a modified flagella/cilia ...

Relationship of field and in vitro fertility of dairy bulls with sperm parameters, including DAG1 and SERPINA5 proteins

Frontiers in Animal Science, 2023
IntroductionSperm interacts with the female reproductive tract and oocyte through proteins, and these cell-to-cell interactions may play a role in sperm fertility.

The missing linker between SUN5 and PMFBP1 in sperm head-tail coupling apparatus

Nature Communications, 2021
The sperm head-to-tail coupling apparatus ensures sperm head-tail integrity, but mechanistic insights remain limited. Here the authors demonstrate that CENTLEIN links and controls the interaction between SUN5 and PMFBP1, indicating that its impairments ...

A study of sperm quality assessment: Morphological defect in patients with normal sperm count

National Journal of Physiology, Pharmacy and Pharmacology, 2023
Background: Sperm morphology is the major benchmark in assessment of male infertility. There are limited studies available on frequency of qualitative defects of sperm in patients with normal sperm count.
