Startup cost: $0 - $500

Low-end estimate: Becoming a sperm donor typically requires no upfront costs. Most clinics or sperm banks cover any necessary medical tests and screenings. High-end estimate: If someone wants to optimize their health and lifestyle to increase the quality of their sperm, they might invest in supplements, a gym membership, or a healthier diet, which could cost up to $500. These are optional and not required by clinics. There are no hidden fees, as clinics usually handle all necessary procedures and tests. The process is generally low-cost, with potential earnings rather than expenses.
