Artificial inseminationIn 1939, a rabbit conceived by artificial impregnation, was the first such animal in the U.S. to be displayed. The event was the 12th Annual Graduate Fortnight at the New York Academy of Medicine. Dr. Gregory Pincus, an American biologist, had removed an egg from the ovary of a female rabbit and fertilized it with a salt solution. The egg was then transferred to the uterus of a second rabbit, which functioned an "incubator." The young rabbit was born in Oct 1939. Dr. Pincus, of Clark University conducted his experiments at Harvard University, Cambridge, Mass. In the same year, Pincus and colleagues were the first to show how oocytes of various animals would undergo maturation if released from their follicle and cultured in vitro. |
