Small annual meetings on reproduction, from which the Society for the Study of Fertility (SSF) was to develop, started in 1944. The proceedings of these meetings were first published in 1947 by the Family Planning Association under the title Conference on Infertility. From 1949 to 1953, Heffers published the Proceedings of the Society for the Study of Fertility and, from 1954, Blackwell Scientific Publications continued with Studies on Fertility. As early as 1952, the possibility of producing a quarterly journal was raised, but finance proved a major obstacle. In 1956, Alan Parkes proposed, on behalf of the SSF, that the Journal of Endocrinology should become the official organ of the SSF, and that it should be renamed the Journal of Endocrinology and Reproduction. Solly Zuckerman supported this initiative, but views of members of the Society for Endocrinology on the proposal were so divided that the idea was abandoned.
In 1957,

Summary.
Luteinized ovaries of the opossum incubated in Krebs-Ringer bicarbonate buffer synthesized progesterone. Such synthesis could be enhanced by lh but not by fsh or prolactin. The ovaries did not incorporate acetate-1-14C into progesterone but did convert cholesterol-1,2-3H and pregnenolone-7α-3H into progesterone. lh tended to stimulate cholesterol conversion into progesterone but the effect was not significant. The thesis is advanced that, regardless of the luteotrophic or luteolytic mechanisms operating in different species, lh is steroidogenic. It is suggested that the control mechanisms for the oestrous cycle are simpler in marsupials than in other mammalian species and an understanding of the processes involved in marsupials would give a useful baseline for comparisons with other species.
