Iatrogenic ejaculation disorders and their prevention

, 2001
Ejaculation is mediated by sympathetic fibers originating from the D10-L2 medullar center. These nerves rise from the lumbar ganglia of the paravertebral sympathetic trunk and travel posteriorly to the vena cava and then to the interaortocaval space, on ...

Sperm Selection Using Micro Swim‐Up: Improvement of Chromatin Integrity Compared to Density Gradient Centrifugation

Andrology, EarlyView.
ABSTRACT Background Selecting high‐quality spermatozoa with optimal nuclear integrity is a crucial step in assisted reproductive technologies (ART). While density gradient centrifugation (DGC) is widely used, the associated centrifugation steps may induce cell stress, potentially damaging sperm DNA.

Associations Between Sperm DNA Fragmentation and Lifestyle Factors

Andrology, EarlyView.
ABSTRACT Background Sperm DNA fragmentation index (DFI) has been proposed as a supplementary biomarker to traditional semen parameters in the evaluation of male infertility. However, its determinants and clinical relevance remain unclear, particularly regarding modifiable lifestyle factors.

Pathophysiology of Premature Ejaculation

The Journal of Sexual Medicine, 2011
ABSTRACTIntroductionAlthough the characteristics of premature ejaculation (PE) are established, the exact aetiology is largely unknown. Genetic, neurobiological, pharmacological, psychological, urological and endocrine factors have all been proposed. In addition PE and erectile dysfunction are often co-morbid.AimThis article provides an overview of the

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis

Andrology, EarlyView.
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.
