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.

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.

Changes in Semen Volume Following Vasectomy: A Retrospective Case–Control Analysis

Andrology, EarlyView.
ABSTRACT Background Vasectomy is the most common non‐diagnostic procedure performed by urologists and the only permanent form of sterilization routinely offered to men. Though vasal fluid has been estimated to represent less than 10% of seminal volume, studies describing the effect of vasectomy on semen volume remain limited.

Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

Andrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Male Sexual and Reproductive Health in Diabetes and Obesity Pharmacotherapy: A Source‐Triangulated Counseling Map

Andrology, EarlyView.
ABSTRACT Background Drugs used for diabetes and obesity increasingly shape male sexual and reproductive counseling, but clinical studies, trial registrations, regulatory labels, and patents answer different questions. Objectives The objective is to map these sources and define what each can support when counseling men receiving metabolic drugs ...
