Is Insulin useful for fertility?

Whether insulin is useful for fertility cannot be answered with a simple yes or no. In reproductive medicine, insulin is not a standard fertility treatment. However, insulin plays a key role in metabolic conditions like Polycystic Ovary Syndrome (PCOS), which is often linked to insulin resistance. In PCOS patients, insulin-sensitizing drugs such as metformin (which enhances insulin action) can improve ovulation and egg maturation. Direct insulin administration is typically reserved for diabetes management, where good glycemic control supports overall reproductive health. The evidence for insulin itself as a fertility aid is weak; no robust clinical trials support routine insulin use to enhance fertility in non-diabetic women. The provided context does not contain specific data on this topic, limiting the strength of any conclusion. Safety note: Insulin must only be used under medical supervision due to the risk of hypoglycemia.
