Summary
This study tests whether taking probiotics daily for about 100 days can improve sperm count, movement, and shape in men with infertility. Sixty men aged 20 to 45 will be randomly assigned to receive either probiotics or a placebo. Researchers will measure sperm quality at the start, at 60 days, and at the end of the study using advanced lab tests.
