EXPERIMENTAL ECTOPIC IMPLANTATION OF EGGS AND EARLY EMBRYOS IN GUINEA-PIGS

in Reproduction

Summary.

Successful primary abdominal implantation and development has been induced in the guinea-pig by transection of the oviducts 1 to 3 days after mating although attempts made to induce tubal implantation by ligature of the utero-tubal junction failed.

Development also took place in four out of eighteen pre-implantation eggs (aged 4 to 5 days post coitum) transplanted into the kidney or abdominal muscle. In six cases, where post-implantation conceptuses (aged 9½ and 12 days post coitum) were transplanted into the spleen, testes or anterior chamber of the eye, growth and differentiation was observed on each occasion.
