Development of a Noble On-Site Dual Screening System for Male Fertility of Sperm Count and Hyaluronidase Activity

The World Journal of Men's Health
Purpose: To develop a noble on-site dual screening system for sperm concentration and hyaluronidase (HAdase) activity of male fertility based on lateral-flow assay methods, and to evaluate the effectiveness of this dual screening system.

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

Animal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Protective Effect of All-Trans Retinoic Acid in Cisplatin-Induced Testicular Damage in Rats

The World Journal of Men's Health, 2019
Purpose: To investigate the effects of all-trans retinoic acid (ATRA) in cisplatin (CP)-induced testicular damage in rats. Materials and Methods: Twenty-eight male Wistar rats were divided into four groups: Control, ATRA alone, ATRA+CP, and CP alone ...

Year of birth and sperm count in 10 Danish occupational studies [PDF]

, 1998
Objectives: Several reports indicate a secular decline of human sperm counts. It is still not known if these findings are artifacts related to shortcomings in the data and applied methodologies.

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Predictive value of sperm morphology and progressively motile sperm count for pregnancy outcomes in intrauterine insemination [PDF]

, 2016
OBJECTIVE: To investigate the value of sperm parameters to predict an ongoing pregnancy outcome in couples treated with intrauterine insemination (IUI), during a methodologically stable period of time.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Analysis of the correlation between sperm DNA integrity and conventional semen parameters in infertile men

Urology Research and Practice, 2019
Objective: A male factor is responsible in approximately 30-40% of couples receiving infertility treatment. Routinely, such couples undergo semen analysis including parameters such as sperm count, motility and morphology. Generally, the analysis of sperm
