NCT06544278
The Impact of Probiotics on Sperm Quality in Middle-aged Men
The clinical trial aims to investigate the impact of probiotic strain BL21 on sperm quality among 46 middle-aged male participants. The primary objective is to validate whether probiotic strain BL21 can effectively improve sperm quality among middle-aged male participants. Initially, participants were instructed to consume the recommended amount of probiotic powder for approximately 8 weeks. At baseline, week 4, and week 8 endpoints, semen analysis, hormone level testing, serum cytokine testing were conducted on the participants, and stool samples were collected from them.

A Clinical Trial Evaluating the Efficacy and Safety of Leflutrozole on Testicular Function
The goal of this clinical trial is to evaluate three doses of the drug leflutrozole on improvement of semen quality in men. It will also study the safety of leflutrozole. The main questions it aims to answer are: * Does leflutrozole improve semen quality? * What medical problems do participants experience when taking leflutrozole? Researchers will compare leflutrozole to a placebo (a look-alike substance that contains no drug). Participants will: * Take leflutrozole or a placebo orally once a week for 16 weeks. * Visit the clinic every 4 weeks for checkups and tests. * Provide semen samples to measure changes in semen quality. * Have their blood tested to measure hormone levels and ensure safety. * Be monitored for any side effects.
