Up to 20% of male infertility is caused by abnormal DNA organization of the sperm and anomalies of the sperm apoptosis. The aim of this study was to investigate the sperm DNA apoptosis and viability in patients undergoing intrauterine insemination (IUI) and intracytoplasmic sperm injection (ICSI). In the second part of the analysis, sperm DNA apoptosis and viability were investigated in patients with oligozoospermia and normospermia respectively. A total of 45 IUI and 38 ICSI patients were included in this study. Annexin V analysis was performed to investigate the sperm viability, and TUNEL assay was used to evaluate the sperm DNA apoptosis. Further investigations using 12 oligozoospermia and 11 control samples for sperm viability and sperm DNA apoptosis at different incubation periods and temperatures were performed. The results of this study showed a negative correlation between the sperm DNA apoptosis in IUI patients, but no relationship was observed for the ICSI patients. The second part of this study showed that incubation of semen samples at 37°C for 3 h has detrimental effects on the sperm DNA integrity. In conclusion, the incubation of semen at high temperatures affects the sperm quality. The results of this study showed that these tests can be beneficial for the infertile couples to achieve pregnancy.

Distinct and interdependent functions of three RING proteins regulate recombination during mammalian meiosis.

During meiosis, each pair of homologous chromosomes becomes connected by at least one crossover, as required for accurate segregation, and adjacent crossovers are widely separated thereby limiting total numbers. In coarsening models, this crossover patterning results from nascent recombination sites competing to accrue a limiting pro-crossover RING-domain protein (COR) that diffuses between synapsed chromosomes. Here, we delineate the localization dynamics of three mammalian CORs in the mouse and determine their interdependencies.

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.

Purpose: Contemporary antiretroviral (ARV) medications are used by millions of men for HIV treatment worldwide. Limited data exist on their direct effect on sperm motility. This pilot study hypothesizes that in vitro exposure to ARVs will reduce sperm kinematic and motility parameter values.

Childhood maltreatment exposure (CME) increases the risk of adverse long-term health consequences for the exposed individual. Animal studies suggest that CME may also influence the health and behaviour in the next generation offspring through CME-driven epigenetic changes in the germ line. Here we investigated the associated between early life stress on the epigenome of sperm in humans with history of CME.

Background: The massive harmful effects of cigarette (tobacco) smoking on reproduction and fecundity are apparent. Even smoking cessation is often suggested for infertility patients by clinic doctors, while the impact of smoking cessation on semen quality in patients with oligoasthenospermia is uncovered.
Methods: Ninety oligoasthenospermia patients with long tobacco smoking history were directed by andrology doctors to cease smoking, and their cessation was followed up for 3 to 6 months.
