Male factors account for approximately 50% of reproductive pathology. Different disorders, including urogenital and endocrine system development abnormalities, lead to testicular and gametogenesis defects. Parallely, studies have reported that somatic and germ cell genome decay are a major cause of male infertility. It has been shown that in somatic karyotype, there is a higher incidence of chromosomal aberrations in infertile men than neonatal population and significant chromosome Y microdeletion or specific gene alterations in affected spermatogenesis. Karyotyping and FISH application at somatic and germ cell levels are no longer sufficient to investigate the potential contribution of genome disorders on male infertility. A wide range of molecular methods are required for better understanding of male infertility causes. Molecular omes and omics techniques have become a great tool to investigate male infertility from chromosome to protein. This review reports different molecular tests and methods that can be offered for male infertility investigation.

Multiple conditions can cause hypoxia in the testis, including exposure to high altitude, sleep apnoea, testicular torsion and varicocele. Varicocele accounts for up to 44% of instances of primary infertility, but the cumulative contribution of hypoxic conditions to male infertility is undefined. Results of controlled hypobaric hypoxia studies have demonstrated a substantial detrimental effect of short-term and long-term exposures on sperm; however, downstream effects on embryo development and offspring health are less well understood.

Recently, the World Health Organization recommendation for abstinence time for semen analysis has been challenged in some studies and many of them have supported the advantages of a second short abstinence ejaculation. More evidence is needed to approve this for clinical use. This study aimed to compare the average routine abstinence time (2-7 days) with the short time (1-2 h) on sperm quality based on functional parameters in a population of oligo-astheno-teratozoospermia (OAT) men.

The proteasome, an evolutionarily conserved proteolytic complex comprising the 20S core particle and 19S regulatory particles, performs both shared and distinct functions across various tissues and organs. Spermatogenesis, a highly complex developmental process, relies on proteasome activity at multiple stages to regulate protein turnover. In this study, we selected the 20S subunit PSMA1 and 19S regulatory subunit PSMD2 to investigate the potential functions of the proteasome in spermatogenesis.

Genetic studies in mice have demonstrated that retinoic acid receptor alpha (RARα) deficiency leads to male infertility without affecting overall viability, suggesting that pharmacological inhibition of this receptor could be a viable contraceptive strategy. This review describes the use of experimental approaches to develop RARα-selective antagonists for male contraception. Initial studies with BMS-189453, a pan-RAR antagonist, showed significant testicular degeneration and reversible infertility in mice.

Background: Many studies have reported that electronic health (e-health) care helps health professionals manage patients undergoing assisted reproductive technology (ART) and improves their reproductive outcomes and psychological distress. However, little is known about the effectiveness of e-health care on the health outcomes of patients undergoing ART.
Objectives: This study aimed to evaluate the effectiveness of e-health care on patient-centered health outcomes, such as live birth rate, pregnancy rate, time to pregnancy, etc.
