Brief Summary:
Why is this study being done? Obesity can harm men's fertility by lowering sperm quality and hormone levels, making it harder to have children. Weight loss through diet and exercise helps, but it's often hard to stick with. New medicines called GLP-1 receptor agonists, like semaglutide (Ozempic) and tirzepatide (Mounjaro), help people lose weight and improve health. Early studies suggest these drugs might also boost sperm health in obese men, but more proof is needed. This study tests if these drugs can safely improve fertility in obese men who are having trouble conceiving.
What will happen in this study?
This is a 48-week study at several hospitals in China. About 180 men will be randomly assigned to one of three groups:
Group 1: Standard lifestyle changes, like a healthy diet and exercise, guided by experts.
Group 2: Weekly injections of semaglutide, starting low and increasing as tolerated.
Group 3: Weekly injections of tirzepatide, starting low and increasing as tolerated.
All men will have regular check-ups, including blood tests, semen analysis, and weight measurements. We will track sperm quality, hormone levels, weight loss, and whether their partners get pregnant naturally. The study includes an 8-week adjustment period, 24 weeks of treatment, and 16 weeks of follow-up.
Who can join this study? Men aged 20-45 who are married, obese (BMI 28 or higher or waist size 90 cm or more), and have been trying to have a baby for at least a year without success due to low sperm count or poor sperm movement. Their female partners must be under 40 and have no major fertility issues. Men must be willing to attend visits and provide samples. People with serious health problems, recent use of similar drugs, or other causes of infertility (like genetic issues) cannot join.
How long will this study last? The full study lasts 48 weeks (about 11 months), with visits every 4-8 weeks, plus monthly phone check-ins for pregnancy updates.
What are the possible benefits and risks? Benefits: If the drugs work, men may lose weight, improve sperm quality, and have a better chance of their partners getting pregnant naturally. They might also feel healthier overall. Risks: Common side effects include nausea, vomiting, or diarrhea from the drugs, which usually improve over time. Rare risks include pancreas inflammation or gallbladder issues. Lifestyle changes might cause minor injuries from exercise. All side effects will be monitored closely, and participants can quit anytime. Insurance covers any study-related harm.
