In cryptozoospermia or severe oligozoospermia is sperm freezing useful? [PDF]

open access: yesBasic and Clinical Andrology, 2014
Intracytoplasmic Sperm Injection (ICSI) is an Assisted Reproduction Technique (ART) which offers the chance to conceive to patients presenting very low sperm counts (cryptozoospermia/severe oligozoospermia). Sperm freezing before the oocyte pick-up, can prevent from a lack of spermatozoa on the day of the ICSI. It can avoid the cancellation of the ICSI

Male Infertility Diagnosis: Improvement of Genetic Analysis Performance by the Introduction of Pre-Diagnostic Genes in a Next-Generation Sequencing Custom-Made Panel

open access: yesFrontiers in Endocrinology, 2021
BackgroundInfertility affects about 7% of the general male population. The underlying cause of male infertility is undefined in about 50% of cases (idiopathic infertility).

Smoke, alcohol and drug addiction and male fertility [PDF]

open access: yes, 2018
In recent decades, the decline in human fertility has become increasingly more worrying: while therapeutic interventions might help, they are vexing for the couple and often burdened with high failure rates and costs.

Healthy and unhealthy dietary patterns and sperm quality from the Led‐Fertyl study

open access: yesAndrology, EarlyView.
Abstract Background Dietary patterns may affect sperm quality, but the scientific evidence is limited. Objective To evaluate the association between adherence to different a‐priori dietary patterns and sperm quality parameters in healthy reproductive‐age men.

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]

open access: yes, 2006
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

EP300‐interacting inhibitor of differentiation 3 is required for spermatogenesis in mice

open access: yesAndrology, EarlyView.
Abstract Background Mammalian spermatogenesis is a highly complex process of cell proliferation, meiosis, and differentiation. A series of genes are expressed in an orderly and precise manner to ensure spermatogenesis, with chromatin undergoing intricate changes throughout.

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.
