Research summary

Longstanding interest in the prenatal development of individuals into males and females. Based on the principle that the testes of fetuses develop earlier than their ovaries, I formed the hypothesis that the development of males may require a faster rate of growth than that of females; and measurements undertaken by my colleagues and myself showed that a difference in size could in fact be detected before any other difference seen under the microscope.
