Pill No Effect on Sex of Future Children, Harvard Study Says
Harvard researchers led by Dr. Kenneth J. Rothman analyzed 6,109 births in the Boston area from pill users and found a near even split of male and female babies. They counter the 1974 Hungarian Lancet report claiming fewer boys among children of pill users, noting their much larger sample size and that oral contraceptives appear not to influence offspring sex.
