Role of intra‐individual variation in the detection of thresholds for DFI and for misclassification rates: A retrospective analysis of 14,775 SCSA® tests

open access: yesAndrology, EarlyView.
Abstract Background Sperm DNA damage is associated with reduced male fertility after natural conception and intrauterine insemination. However, the impact on in vitro fertilization (IVF) and especially intracytoplasmic sperm injection (ICSI) treatments is still unclear.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

open access: yesAndrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Semen cryopreservation and storage in liquid nitrogen: Impact on chromatin compaction

open access: yesAndrology, EarlyView.
Abstract Background Sperm cryopreservation is a consolidate option for long‐term male fertility preservation. The freezing/thawing procedure causes detrimental effects to spermatozoa, including damage to viability, motility, membrane composition, and DNA, whereas the effect on sperm chromatin compaction is less studied.

Inhibition of ROS1 activity with lorlatinib reversibly suppresses fertility in male mice

open access: yesAndrology, EarlyView.
Abstract Background Inhibition of sperm maturation in the epididymis is a promising post‐testicular strategy for short‐acting male contraceptives. It has been shown that ROS1, a receptor tyrosine kinase expressed in the epididymis, is essential for epididymal differentiation, sperm maturation, and male fertility in mice.

A WHO 2021‐based comprehensive scheme outlining sperm parameters’ associations with IVF outcomes in PGT‐A cycles

open access: yesAndrology, EarlyView.
Abstract Objective To examine the association between semen parameters, assessed according to World Health Organization (WHO)‐2021 criteria, and paternal body mass index (BMI) and age, with embryological and clinical outcomes in ICSI cycles involving preimplantation genetic testing for aneuploidy (PGT‐A).
