Phenotypic continuum and poor intracytoplasmic sperm injection intracytoplasmic sperm injection prognosis in patients harboring HENMT1 variants

Andrology, EarlyView.
Abstract Background Small RNAs interacting with PIWI (piRNAs) play a crucial role in regulating transposable elements and translation during spermatogenesis and are essential in male germ cell development. Disruptions in the piRNA pathway typically lead to severe spermatogenic defects and thus male infertility. The HENMT1 gene is a key player in piRNAs

Ascorbic acid 2‐glucoside improves survival, quality, and fertility of frozen‐thawed C57Bl/6J and C57Bl/6N mouse spermatozoa

Andrology, EarlyView.
Abstract Background Ascorbic acid 2‐glucoside (AA2G) is a stabilized form of ascorbic acid and a potent antioxidant. Ascorbic acid is present in the testes and epididymis and helps maintain the physiological integrity of reproductive organs. Its properties have been utilized to protect spermatozoa of different species from oxidative stress.

Benchmarks defining high‐quality sperm in the common marmoset (Callithrix jacchus)

Andrology, EarlyView.
Abstract Background Common marmosets (Callithrix jacchus) are increasingly recognized as valuable nonhuman primates (NHPs) for biomedical research due to their small size and short reproductive cycle and lifespan relative to other NHP species. Maximizing the utility of captive research marmosets, including genetically manipulated animals, will require ...

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

Andrology, 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.

Abstract Infertility affects 1 in 7 couples. An etiological diagnosis is made to plan treatment. In a quarter no diagnosis can be established, hence a diagnosis of unexplained infertility is made. IF conception does not happen after an etiological diagnosis based treatment or unexplained infertility is diagnosed, in-vitro fertilisation (IVF) is the ...

Aspirin for in vitro fertilisation

2011
Aspirin is used to improve the outcome in women undergoing in vitro fertilisation despite inconsistent evidence of its efficacy. The most appropriate time to commence aspirin therapy and the length of treatment required are also still to be determined. This is an update of the review first published in 2007.To determine the effectiveness and safety of ...
