Oil-mediated nano emulsion, a more advanced technology than other commercial extenders, will protect spermatozoa for extended periods against ROS and cryo injuries. The study is designed to elucidate the most suitable extender to preserve infertile subjects' sperm cells against ROS damage. This is a significant step forward for the andrology society, as it introduces the use of a nano emulsion extender (natural oil extract) for the first time, particularly for those who are undergoing urology-related defects.

Biologically inspired synthesis of nanoparticles was found to be more attractive in metal nanoparticle synthesis. The present study reported an biogenic synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract. On this basis, the aqueous leaf extract of acted as a reducing agent and stabilizing agent to synthesize highly stable AgNPs at ambient temperature.

Augmented escape of nanostructures to the ecosystem has necessitated the comprehensive study of their impact, especially on plants. In the current study, hematite nanoparticles were prepared by employing garlic extract and checked for their cytogenetic effect on onion roots and germination characteristics of five agricultural crops (, , , and ) in the concentration range of 20-100 mg/L. Onion roots exhibited an increased mitotic index till 60 mg/L dosage, beyond which trend decreased marginally.

Background: Plants are the major sources of antioxidants, which maintains oxidant: antioxidant state or is to protect from excessive reactive oxygen species in case of cryo medium selection though maintain sperm stability.

Bottleneck: Cryo preservation of infertile smokers is challengeable with the available medium due to over production of ROS hitches, were cause loss of sperm physiology. Hence, a novel medium is needed to store/protect sperm cells of infertile smokers where they attending/ongoing IVF or oncogenic surgical treatment.

In modernized lifestyle smoking is one of the trendy, psychological, and socioeconomic scenarios of young adolescents mainly in the age of the reproductive stage. Based on a number of cigarettes smoked, age, and duration of the smoke, the study aims to search for the profound effects of smoking and its impact on semen parameters, sperm-DNA integrity, and fragmentation of sperm DNA with cotinine and apoptotic caspase-3 marker in the seminal plasma of fertile and infertile smokers. To determine oxidative damage by 8-hydroxy deoxyguanosine (8-OHdG) from isolated sperm DNA (steps: reactive oxygen species washing by nitro blue tetrazolium (NBT), sperm lysis, salt digestion, ethanol washing, and finally with high-performance liquid chromatography analysis).

Smoking releases cadmium (Cd), the metal toxicant which causes an imbalance in reactive oxygen species level in seminal plasma. This imbalance is envisaged to impair the sperm DNA morphology and thereby result in male infertility. In order to correlate this association, we performed in vitro and in silico studies and evaluated the influence of reactive oxygen species imbalance on sperm morphology impairments due to smoking.
