The chemistry of sex

Thousands of answers have been offered—but surprisingly few by biologists, including brain scientists. While scientists regard other complex emotional states such as depression, anxiety, or fear as complex, but not unfathomable, love is relegated to the poets and songsters. Certainly such love can be a joyous state, but it is also capable of producing deeply disturbing, even dangerous results.

Within the space of a decade we have seen not only the isolation of the various female and male sex hormones but also the elucidation of the molecular structure of these complicated compounds and their preparation in the laboratory from inactive substances. In making these achievements possible certain contributions wereof prime importance. For the isolation of a hormone a reliable bioassay procedure is necessary, and it was the develop-ment of the Allen-Doisy vaginal smear method for assay of the estrogens which made possible the isolation of the interesting series of these hormones which we now know.
