IVF is one of the most successful treatments for both male and female infertility. Success rates vary by age and health, but on average, women under 35 have a 40–50% chance per cycle. For men with low sperm count or motility, IVF with ICSI (injecting a single sperm into the egg) greatly improves the odds. While it’s not guaranteed, IVF offers hope to many couples and has helped millions build families. A fertility specialist can give you a clearer picture based on your unique situation.
