ZAN, IZUMO1, and TMEM95 Protein Domains Identify the Physiological Status of the Sperm

Andrology, EarlyView.
ABSTRACT Background Infertility is a growing concern, which has led to an increase in the use of assisted reproductive techniques, involving in vitro sperm capacitation. Nonetheless, the optimal capacitation time remains a matter of debate, and it is unknown whether it has an impact on the localization of key membrane proteins.

A Systematic Review on the Presentation and Management of Segmental Testicular Infarction

Andrology, EarlyView.
ABSTRACT Background Segmental testicular infarction (STI) is a rare and likely underdiagnosed cause of acute scrotal pain. Its clinical and imaging presentation often mimics testicular torsion or malignancy, frequently leading to unnecessary surgical intervention.

Children Born Using Ejaculated Sperm From Men With Klinefelter Syndrome. Is Sperm Production Associated With Testicular Volume?

Andrology, EarlyView.
ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

Seminal Biomarkers and Sperm Proteomic Signatures Differentiate Acute and Chronic Male Accessory Gland Inflammation

Andrology, EarlyView.
ABSTRACT Background Male accessory gland inflammation (MAGI) comprises a heterogeneous group of inflammatory conditions that may differentially affect the seminal microenvironment and sperm function. However, whether transrectal ultrasound (TRUS)‐defined MAGI phenotypes correspond to distinct biological profiles remains insufficiently characterized ...

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.

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.

Sperm count and sperm motility decrease in old rats

Physiology & Behavior, 2013
Sexual behavior declines with age in male rats. The rate and magnitude of this decline may depend on the amount of prior sexual experience and a number of other, unidentified factors. Age-dependent changes in the characteristics of ejaculate quality in rats have not been described earlier, and the relationship between such changes and modifications of ...

SPERM-COUNTS AFTER VASECTOMY

The Lancet, 1973
The letter writers remark upon the discord among clinicians and pathologists shown by the correspondence in this journal following the writers suggestion (March 24 p.663) that semen-counts may be unnecessary provided 20 ejaculations have occurred after an effective vasectomy procedure.
