A method of using a fertility enhancement food to improve human fertility. This fertility enhancement food consists of transfer factor, lactic acid generating bacteria, and/or glucans in appropriate combinations. The fertility food, administered correctly, reduces cortisol levels. High cortisol interferes with conception and stable pregnancies. Dosage amounts are adjusted for client weight. Consumption frequency may be adjusted in response to cortisol measurements. Typically, consumption of the fertility food begins seven or more days before planned conception.
