A seat (chair, stool, etc.) has a contoured front at seat base so that the mentioned front recessed in the middle towards seating center and/or towards downward, creating an open area for a seated person, which is under the body part around testes of a seated male person, so that the dispersion of body heat from that area via air circulation will not be blocked by seat base, and at the same time the pressure between testes area and seat base will be reduced or eliminated, thereby improving physiological condition for sperms, and in turn may increase sperm activity and may reduce the possibility of infertility.
