Now that in vitro fertilization is common, genetic engineering is a household word and contraceptive vaccines are on the horizon, health scientists and officials are eyeing what the future holds for reproductive biology research. More than 1,100 researchers and policy-makers will discuss current developments and future directions in that field July 9-12 during the annual meeting of the Society for the Study of Reproduction at UC Davis. The society is a national scientific organization that promotes research in reproductive biology and publishes the journal Biology of Reproduction. Highlights of the meeting will include a mini-symposium focusing on the role of brain chemistry in reproductive behavior; a National Institutes of Health symposium addressing public health, economic and political issues related to reproductive biology; and a mini-symposium examining the mechanisms by which environmental toxicants interfere with animal -- and potentially human -- health.
