...years ago Harvard's Physiologist Gregory Goodwin Pincus placed a rabbit's ova in a bottle with a rabbit's sperm, shook them together for 20 minutes. Next he placed the fertilized ova in the fallopian tube of a rabbit doe who 33 days later bore a litter of six healthy bunnies. They were no kin to her. She was simply their host-mother (TIME, March...
Last year Dr. Pincus fertilized rabbit ova with rabbit sperm in the same way, tried to make the ova develop in glass containers. That ectogenic experiment failed...
Thereupon Dr. Pincus proceeded to perform other genetic tricks which, when he reported them to the Federation of American Societies for Experimental Biology in Washington last week, stirred the Press to front-page speculation as to the imminence of immaculate conceptions and substitute motherhood in humans...
...Pincus' newest trick was a modification of the late (1859-1924) Jacques Loeb's method of producing fatherless sea urchins by soaking sea urchin eggs in very salty water, of producing fatherless frogs by pricking frog eggs with a needle. Dr. Pincus soaked some rabbit ova in brine. Other rabbit ova he heated to 113° F., about 10° above normal. When he placed salted or heated ova in the fallopian tubes of rabbits, the rabbits became pregnant. Too impatient to wait 33 days for normal parturition, he killed the does, slit them open, found well-developed...
Household affairs kept Dr. Pincus from leaving Cambridge for Washington last week. His absence permitted science editors to have a field day. Wrote William Laurence of the New York Times: "As rabbits and men belong to the mammalian group, the work is viewed as pointing toward the possibility of human children being brought into the world by a host-mother not related by blood to the child...
