Objectives: This study aimed to determine the relationship between oxidative stress (OS) measured by the oxidation-reduction potential (ORP) and the results of semen analysis among men from infertile couples.
Methods: This cross-sectional study included 166 men from infertile couples, determined according to the World Health Organization guidelines. The general characteristics, semen analysis, sperm chromatin dispersion assay, and ORP of all subjects were evaluated and analyzed statistically.
Results: Among 166 men from infertile couples, individuals with OS had a significantly higher DNA fragmentation index (DFI) than men without OS (22.37% ± 11.67% vs. 17.98% ± 8.98%). The sperm concentration, total sperm count, motility rate, and normal morphology were negatively correlated, while and an abnormal head and neck-tail were positively correlated with ORP. There was also a positive association between the DFI and OS level. The optimal ORP threshold for determining sperm quality was 0.77 mV/10 sperm/mL (sensitivity, 50.4%; specificity, 93.5%; positive predictive value, 52.9%; negative predictive value, 32.3%).
Conclusions: Determining the ORP suggests that OS has an adverse effect on the total sperm count, sperm motility, sperm concentration, morphology, vitality, and DNA fragmentation index.

Research Question: Male infertility accounts for almost half of all infertility cases worldwide, with idiopathic male infertility accounting for up to 30% of the cases. Sperm proteomics has revealed critical molecular pathway changes in men with infertility. However, the sperm mitochondrial proteome remains poorly understood.

Objectives: This study investigates sperm utilization and disposal patterns in Oligoasthenoteratozoospermia (OAT) patients undergoing long-term sperm storage. OAT is a major contributor to male infertility. Cryopreservation is a common practice as a "fertility insurance" in case of further deterioration until azoospermia.

The Y chromosome contains a set of genes with testis-specific expression that are responsible for the development of testes and spermatogenesis, and it is the most important target in the search for genetic causes of male infertility. Most of these genes are located in the "azoospermia factor" AZF locus (regions AZFa, AZFb, and AZFc) on the long arm of the Y chromosome. Microdeletions of the Y chromosome, leading to the removal of the entire AZF locus as well as one or more regions (complete deletions), are one of the leading causes of spermatogenesis impairment and infertility.

Background: The possibility of future parenthood is a highly relevant issue for patients of reproductive age facing oncologic treatment. This study aimed to investigate how fatherhood was achieved in a patient cohort of adolescents and young adults (AYAs) banking semen at time of cancer diagnosis and to determine the effectiveness of cryopreservation aimed at fertility preservation in the cohort.
Materials And Methods: Observational cohort study examining AYAs with a cancer diagnosis who underwent semen banking for fertility preservation at Karolinska University Hospital 1988-2020, as part of the Stockholm regional fertility preservation program.

Background: Lithium (Li) is widely used in the treatment of bipolar disorder, but it may lead to toxicity in the reproductive system. Considering the harmful effect of Li consumption on fertility and the positive effect of magnesium sulfate (MgSo) and moderate-intensity training (MIT) on improving the quality of men's sperm, the current research was conducted to determine the impact of MIT and MgSo on infertility caused by Li.
Materials And Methods: Seventy-two male rats were divided into 12 groups, control, Li10 mg/kg/day/ip, MgSo 80 mg/kg/day/ip; MIT; Li40 mg/kg/day/ip; Li10+MgSo; Li10+MIT; Li10+MgSo+MIT; Li40+MgSo; Li40+MIT; Li40+MgSo+MIT.
