Transplantation experiments involving ovaries from normal adults and adults arising from the above chemical treatment were undertaken. The object was to investigate whether apholate-induced female infecundity results from direct effects on the ovary or from indirect effects on the hormonal and/or yolk protein synthesis or supply.
The fact that the ovary from an untreated female when implanted in the abdomen of an infecund female develops more or less normally, at least in a qualitative sense, following a blood meal indicates that the yolk proteins and the gonadotrophic hormone are available for ovarian development in chemically treated females. Thus, the humoral factors are not involved in female infecundity and the primary site of action of apholate must be the oocyte. The inhibition of the ovaries in apholate-treated females, must be brought about by degenerative changes in the ovary itself.
Quantitatively, fewer untreated follicles developed following implantation in the abdomen of a treated female. Furthermore, they did not reach the same stage of development as they did in untreated environment. Possible mechanisms for this retarded development are discussed.
