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

Andrology, 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.

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

Andrology, 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).

Effects of AZFc (b2/b4, b1/b3, b2/b3, and gr/gr) deletions and primary duplications on the outcomes of the first intracytoplasmic sperm injection treatment cycle: A single‐center retrospective cohort study

Andrology, EarlyView.
Abstract Background Current advances in high‐throughput sequencing technology enable the precise identification of Y chromosome microdeletion and primary duplication in infertile couples, but the mechanism and clinical significance of these mutations in assisted reproductive techniques remain unclear.

Comprehensive diagnostic and therapeutic approach to male factor infertility aimed at natural fertility: A multicentric retrospective cohort study

Andrology, EarlyView.
Abstract Background In infertile couples whose male partner has alterations in semen parameters frequently, a comprehensive andrological approach is lacking and approximately 30–50% are classified as idiopathic infertility. These couples are often directly addressed to assisted reproduction techniques (ARTs).

Initial motility and vitality predict the semen quality after long‐term cryostorage, even in patients with restricted ejaculate parameters

Andrology, EarlyView.
Abstract Background Cryopreservation of human semen is the cornerstone for preserving male fertility before gonadotoxic therapy or in cases of high variability in semen parameters. This is particular crucial in cases of severe oligoasthenoteratozoospermia (OAT), where diminished sperm counts may compromise planned intracytoplasmic sperm injection (ICSI)

Reproductive functions and fertility preservation in men with sickle cell disease

Andrology, EarlyView.
Abstract Background Sickle cell disease (SCD) is a prevalent hereditary disorder with significant morbidity, including potential impacts on male fertility. This study aims to evaluate the semen parameters in men with SCD and assess the outcomes of fertility preservation strategies.
