This document discusses male infertility, including its causes, diagnosis, and treatment options. It begins with an introduction to male infertility and why evaluation is important. Diagnosis involves obtaining a medical history, performing a semen analysis and physical exam, and testing for endocrine, genetic, and other underlying factors if initial tests are abnormal. Treatment may include medical therapies for correctable issues, assisted reproductive technologies like intrauterine insemination or ICSI, or surgery to address problems like varicocele. While male infertility often cannot be cured medically, techniques like ICSI have revolutionized treatment.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

REACTIVE OXYGEN SPECIES (ROS)
Idiopathic oxidative stress contributes to defective spermatogenesis
leading to male factor infertility
Uncontrolled & excessive production of ROS overwhelms the limited
antioxidant defenses in semen resulting in seminal oxidative stress
Seminal oxidative stress correlates negatively with sperm concentration,
motility and function.
Superoxide anion, hydroxyl radical and hydrogen peroxide are major reactive oxygen species
(ROS) present in seminal plasma.

VARICOCELE
Report on varicocele and infertility: a committee opinion
American Society for Reproductive Medicine and Society for Male Reproduction and Urology, Birmingham, Alabama
Practice Committee of the American Society for Reproductive Medicine
Summary
•The diagnosis of varicoceles is based primarily on physical examination.
•Imaging studies are not indicated for the standard evaluation unless physical examination is
inconclusive.
•Only clinically palpable varicoceles have been clearly associated with infertility.
•Adolescents and young men not actively trying to conceive who have a varicocele and
objective evidence of reduced ipsilateral testicular size may be offered varicocele repair.
•Although data are limited and of lower quality, most studies show improvement in semen
parameters and fertility after repair of varicocele.
•Time to improvement in semen parameters is approximately 3 to 6 months.
