Paraoxonase and arylesterase enzymes are corner stones of antioxidant defence. We aimed to compare azoospermic infertile men and normozoospermic individuals with respect to total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), paraoxonase and arylesterase levels in the blood and seminal plasma. Two-hundred consecutive infertility patients and voluntarily participated were included. In the normozoospermic group, TAS, PON, arylesterase values were statistically significantly higher when compared with those in the azoospermic group, while lower TOS and OSI levels were observed in the blood and seminal plasma of azoospermic group. In the semen analyses of normozoospermic group, the correlation between semen volume, sperm concentration, sperm motility and morphology and TAS, TOS, OSI, PON and arylesterase values was examined. A negative correlation was determined between semen volume and OSI. Levels of serum oxidative parameters were higher in the azoospermic group relative to normozoospermic group, but antioxidant parameters were lower than those of the normozoospermic group. Oxidative stress performs an essential role in the aetiology of male infertility by negatively influencing sperm quality and function. Assessment of blood and seminal plasma oxidative profiles might be an important tool to better evaluation of sperm reproductive capacity and functional competence.

Investigating the correlation between micronucleus formation and male infertility has the potential to improve clinical diagnosis and deepen our understanding of pathological progression. Our study enrolled 2252 male patients whose semen was analyzed from March 2023 to July 2023. Their clinical data, including semen parameters and age, were also collected.

Prolactin induced-protein (PIP) has been found to be rich in immunomodulatory epitopes, including -acetyllactosamine (LacNAc) and ,-diacetyllactosamine (LacdiNAc) residues, which may constitute ligands for galecin-3 (Gal-3). In the current study, we aimed to investigate the reactivity of galactose- and -acetylgalactosamine-specific lectins with human seminal plasma PIP. Subsequently, we examined the direct interaction between seminal plasma PIP and galectin-3, and next analyzed whether there are any differences in the interaction associated with impaired semen parameters.

Study Question: Can semen parameters predict long-term health outcomes in men?
Summary Answer: There is a lack of evidence to suggest a higher risk of comorbidities in men with poor semen concentration.
What Is Known Already: Male infertility has been long associated with a higher mortality risk and possibly higher chance of developing comorbidities but there has been less focus on semen analysis as a potential predictive factor.
Study Design Size Duration: We searched PubMed/MEDLINE, EMBASE, and EBM databases from inception to December 2023.

Background/objectives: Male infertility is a complex condition with various underlying genetic factors. microRNAs (miRNAs) play a crucial role in gene regulation, and their disruption can significantly impact fertility. This study aimed to identify variants within miRNA genes and elucidate their impact on male infertility.

There are many factors that affect male fertility such as chronic health problems, psychological factors, and illnesses. Male infertility can be caused abnormal sperm function, low sperm production or even blockages that prevent the delivery of sperm. The aim of the work is to determine the expression pattern of the circularANKLE2 and circularL3MBTL4 RNA in spermatozoa from fertile and infertile males, as well as the relationship between these circRNA transcripts and sperm quality.
