So, is it a girl or a boy? This is the first question parents ask at the birth of an infant. Though the answer is obvious, the mechanism of sex determination is much less so. Researchers at the University of Geneva (UNIGE) attempt to shed light on this complex process by identifying the crucial role played by insulin sm toys and IGF1 and IGF2 growth factors, a family of hormones known for its role in metabolism and growth. In the absence of these factors at the time of sex determination, embryos do not differentiate into either male or female and have no adrenal glands.

Federal monies are available for organizations and programs to advocate for health equity; promote an understanding of the social determinants of health and to develop and disseminate best practices for working with special populations in achieving this goal. 

The Centers for Disease Control has put the reduction of health inequities at the forefront of its work. In addition, my organization, The National Coalition of STD Directors has made the promotion of health equity a priority within the organization and its membership. We now have programs to address the sexual health care needs of Black and Latino gay and bisexual men; to decrease risky behaviors and promote positive decision-making of youth and youth of color; and to provide comprehensive sexual health education to female students at historically black colleges and universities (HBCUs).
