Sex as a prognostic factor in gastric cancer
European Journal of Cancer, 1996The aim of this study was to assess whether survival of gastric cancer patients differed between males and females. Although it is well known that the incidence of gastric cancer is higher for men than for women, the existence of a sex-specific prognosis has seldom been addressed.

Factors affecting the Human Sex Ratio
Nature, 1962WE present here evidence suggesting the existence of at least two kinds of factors affecting the human sex ratio. As the sex ratio we use the number of male births per 100 female births. The evidence is based on family data collected by Geissler1 in 1889 and by ourselves2,3.

The mechanism of sex determination in vertebrates—are sex steroids the key‐factor?
Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2010AbstractIn many vertebrate species, sex is determined at fertilization of zygotes by sex chromosome composition, knows as genotypic sex determination (GSD). But in some species—fish, amphibians and reptiles—sex is determined by environmental factors; in particular by temperature‐dependent sex determination (TSD).
