Synergistic Toxicity of Low‐Concentration Metal Mixture on Male Rats: Reproductive, Renal, and Hepatic Effects

Environmental Toxicology, EarlyView.
ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Role of the epididymis in sperm competition

, 2006
The definitive version is available at www.blackwell-synergy.comAlthough it is generally understood that the testes recruited kidney ducts for reproductive function during the evolution of vertebrates, little is understood of the biological significance ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, EarlyView.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

Finding Mr. Right: Housing Quality Affects Male Mouse Attractiveness to Females, With Implications for Conservation Captive Breeding

Zoo Biology, EarlyView.
Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

Leiomyoma of the Epididymis: A Case Report

, 2006
Tumors of the epididymis, both primary and secondary, and whether benign or malignant, are very rare. Adenomatoid tumors and leiomyoma are the most frequently diagnosed benign tumors of the epididymis. In a review of the American and European literature,

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Expression of NELL2/NICOL-ROS1 lumicrine signaling-related molecules in the human male reproductive tract

Reproductive Biology and Endocrinology
The maturation of spermatozoa is a regulated process, influenced by genes expressing essential secreted proteins in the proximal epididymis. Recent genetic studies in rodents have identified the non-sex steroidal molecular signals that regulate gene ...
