A Study on the Ability of Nanomaterials to Adsorb NO and SO₂ from Combustion Gases and the Effectiveness of Their Separation

Nanomaterials
Climate neutrality for the year 2050 is the goal assumed at the level of the EU27+UK. As Romania is no exception, it has assumed the gradual mitigation of pollution generated by the energy sector, and by 2030, according to ‘Fit for 55’, the share of ...

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.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

A CCNA1 Missense Variant Associated With Chromatid Non‐Disjunction in Abnormal‐Headed Sperm and Male Infertility

Andrology, EarlyView.
ABSTRACT Background Macrozoospermia is a rare form of teratozoospermia characterized by tetraploids, large‐headed spermatozoa with multiple flagella, usually caused by bi‐allelic AURKC mutations. The etiology of atypical phenotypes with a lower proportion of large headed spermatozoa and single flagella however often remains unresolved.

The Indication of ICSI

Journal of Mammalian Ova Research, 2004
The indication of ICSI is generally based on sperm analysis, past therapeutic history, and prediction of fertilization failure. In this study, we attempted to evaluate the usefulness of SMI (Sperm Motility Index) and "split cycle" procedure on ICSI indication.

Pregnancy Outcomes of Intrauterine Insemination Using Microfluidics ZyMot Device for Patients With High Sperm DNA Fragmentation: An Exploratory Retrospective Study

Andrology, EarlyView.
ABSTRACT Background High sperm DNA fragmentation affects male fertility and negatively correlates with sperm survival and pregnancy rates. The use of microfluidic devices allows more rigorous sperm selection, avoiding the centrifugation which is detrimental to DNA integrity.

Company‐Sponsored Fertility Benefits: A Gift‐Exchange and Contextual Intersectionality Informed “FAiRE” Framework Guiding Design and Implementation

Gender, Work &Organization, EarlyView.
ABSTRACT Managing the work‐fertility interface is a major challenge for organizations when implementing fertility policies. These policies cover a broad spectrum of areas including clinical treatments, preservation and storage of eggs and sperm, preimplantation and diagnostics, and non‐clinical family‐building assistance. They also differ from standard

ICSI Outcome in Infertile Couples with Different Causes of Infertility: A Cross-Sectional Study [PDF]

International Journal of Fertility and Sterility, 2013
Background: Different success rate of Intracytoplasmic Sperm injection (ICSI) has been observed in various causes of infertility. In this study, we evaluated the relation between ICSI outcome and different causes of infertility.
