[Three successful cases of artificial insemination in chimpanzees].
Artificial inseminations were performed on two female chimpanzees from July 1981 to April 1983 and three conceptions were obtained. Semen samples collected by rectal probe method of electroejaculation were incubated at 37 degrees C for about 20 minutes for liquefaction. Liquefied portion of the semen was sucked up into polyethylene tube about 30 cm in length attached to a syringe and was inseminated into cervix of each female of which pelvic region was raised in prone position under anesthesia. Ovulation time was speculated by swelling of sex skin in earlier two cases and by urinary LH level in last case. Three offsprings were obtained 234, 235 and 235 days after last insemination, respectively. All of three show normal developments.
