Nano Zinc Oxide Toxicity Varies With Age and Sex in Panagrellus redivivus

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT ZnO NPs can adsorb onto soil particles and potentially enter groundwater. Nematodes and other soil microfauna are vital to the soil's health and nutrient cycles, yet they are seriously endangered by ZnO NPs. A dose–response study using Panagrellus redivivus was applied.

Emerging trends in the management of non‐obstructive azoospermia

open access: yesUroPrecision, EarlyView.
Abstract Ten percent of infertile males have azoospermia, classified into obstructive and nonobstructive types, which require specific medical or surgical treatments. In nonobstructive azoospermia, advancements in microsurgery allow for effective sperm retrieval in about half of cases.

Surgical outcomes in male reconstructive urology: The Qatar experience

open access: yesUroPrecision, EarlyView.
Abstract Introduction Obstructive azoospermia (OA) is a prevalent cause of male infertility in Qatar and globally, with vasectomy reversal (VV) and vasoepididymostomy (VE) being the primary surgical treatments. While microsurgical techniques have advanced, data from the Middle East remain limited, influenced by the region's distinct demographic and ...

Isolated asthenozoospermia: What should we know? A narrative review of literature

open access: yesUroPrecision, EarlyView.
ABSTRACT Male infertility contributes to 20%–70% of infertile couple cases worldwide. One of the key challenges in this area is asthenozoospermia or reduced sperm motility. A particular subset, known as isolated asthenozoospermia (iASZ), in which low motility occurs without abnormalities in sperm count or shape, often goes unnoticed and is not well ...

Systematic review and meta‐analysis of COVID‐19 association with human semen quality: Changes in semen parameters pre‐ and post‐COVID

open access: yesUroPrecision, EarlyView.
Abstract Coronavirus disease (COVID‐19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which may infect the cells through binding with the angiotensin‐converting enzyme 2 (ACE2) receptors that can also be found in the male reproductive organs.

Glycopattern comparison of sperm and exosomes from conventional in vitro fertilization and rescue intracytoplasmic sperm injection: Enhancing sperm motility through exosome‐mediated glycan modulation

open access: yesVIEW, EarlyView.
Infertility is a global concern, with male factors contributing to nearly half of cases. This study compared glycopatterns of sperm and sperm‐derived exosomes from conventional IVF and rescue ICSI (RICSI) patients, revealing key differences in glycan expression.

Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes

open access: yesInsect Science, EarlyView.
Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.

Nicotinamide Riboside Supplementation Alleviates Testicular Aging Induced by Disruption of Qprt‐Dependent NAD+ De Novo Synthesis in Mice

open access: yesAging Cell, EarlyView.
In Qprt‐deficient mice, testicular NAD+ levels decline accelerated with age, leading to mitochondrial dysfunction, disrupted DSB repair, impaired meiotic sex chromosome inactivation, and germ cell loss. Nicotinamide riboside (NR) supplementation restores NAD+ levels and alleviates these defects, highlighting the importance of NAD+ de novo synthesis in ...

Deciphering the Contribution of Circular RNAs to Age‐Related Decline in Sertoli Cell Survivor

open access: yesAging Cell, EarlyView.
Sertoli cell survival is regulated by circAbcb9‐ceRNET. Physiologically, the circAbcb9 sponge activity toward miR‐214‐3p ensures the expression of SOX8 and NOTCH2 targets, both crucial in maintaining SC homeostasis. The aging process negatively affects FUS‐dependent backsplicing activity in Sertoli cells leading to circAbcb9 downregulation, and in turn,

The Effect of Assisted Reproductive Technologies on Human Sex Ratios

open access: yesAustralian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.
