Sexual reproduction evolved as a consequence of evolutionary requirement for diverse phenotypes that can cope with infectious parasites, which mutate much more rapidly than the hosts. Of great interest, we can understand complicated animal (and plant) behaviors as strategies to maximize their reproductive successes. Sexual selection was first advocated by Charles Darwin and is still regarded as one of the most important factors in intra-species evolution. In the present special issue, I have organized reviews of our recent understanding of sexual differentiation, sexual dysfunctions, sexual identity disorders, sexually transmitted infections and gender-related immune disorders. I appreciate the efforts of the contributors, all of whom are my old friends and colleagues, and dedicate this issue to my mentor, the late Dr. Susumu Ohno (1928-2000) who guided me to this field of reproductive genetics and immunology.
