Statement of the Problem: The sex ratio of boys to girls at birth in the human population is 105.8 boys to 100 girls [1]. Does this ratio change with the insemination of selected albumin-separated sperm? The analysis of the births born to couples who underwent sperm separation to influence the sex outcome of their child was carried out from 1990 through 2004. Methodology: Male or female sperm selection was carried out [2], and an intrauterine insemination was performed of the selected sperm as previously reported.
