Abstract: A male undergarment providing a comfort barrier between the groin and outerwear with enhancements for promoting male fertility. By use of less restrictive (and confining) clothing adjuncts to the conventional undergarment, an environment for genitalia, primarily the testes, is acquired that will reduce the level of body heat accumulating in the zone or regions proximate those organs. Elements are used that will reduce the normally existing temperatures: a dam, consisting minimally of a fabric partition, for compartmentally segregating genitalia from the loins; thermally isolation, by use of suitable insulative/reflective fabrics, on the dam and between the segregated organs and groin regions; and, a vented, independent, scrotal compartment. Contrary to the modern norm, the genitalia are allowed to assume a more natural, pendulous suspension, one more conducive to the vitality of spermatozoa.

Abstract: A male undergarment providing a comfort barrier between the groin and outer wear with enhancements for promoting male fertility. By use of less restrictive (and confining) garment adjuncts to the conventional undergarment, an environment for genitalia, primarily the testes, is acquired that will reduce the level of body heat accumulating in the zone proximate those organs. Elements are used that will reduce the normal temperatures within that zone by: compartmentally segregating the penis from the scrotum and the latter from the loins; insulating (by suitable fabric) between the segregated organs and groin regions; and, venting the independent, scrotal compartment. Contrary to the modern norm, the genitalia are allowed to assume a more natural, pendulous suspension, one more conducive to the viability of spermatozoa.
