Probiotics on Sperm Quality in Male Infertility Patients

This randomized, placebo-controlled pilot study aims to evaluate the effects of probiotic supplementation on sperm quality in male patients diagnosed with infertility. Male infertility accounts for approximately 40% of all infertility cases and is closely related to abnormalities in sperm count, motility, and morphology. Factors such as oxidative stress, inflammation, and DNA fragmentation are known to impact sperm function and subsequent fertilization potential negatively. Probiotics are microorganisms that confer health benefits by improving the intestinal microenvironment and regulating immunity. Emerging research suggests that probiotics may reduce oxidative stress and DNA fragmentation in men with asthenozoospermia; however, clinical data on human sperm remains limited. This study seeks to determine whether specific probiotic strains can improve sperm parameters and function in patients with unexplained oligozoospermia, asthenozoospermia, or oligoasthenoteratozoospermia. The study will enroll 60 male participants aged 20 to 45 who meet specific inclusion criteria, including a sperm concentration of less than 50 million/mL, motility less than 40%, and normal morphology (Kruger) less than 4%. Participants will be randomly assigned to either an experimental group receiving probiotics or a control group receiving a placebo for approximately 100 days. Semen samples will be collected and analyzed at three time points: before the intervention (Day 0), during the intervention…
