Orchiectomized rats of the Sprague-Dawley (S-D), Wistar and Wayne strains at varying ages were transplanted with an ovary from immature donors under the abdominal skin and sacrificed 25-85 days after the operation. Corpora lutea (CL) were formed in ovarian grafts in 4 out of 5 S-D rats of 35 day old which had been orchiectomized at day 1 of age and given ovarian transplants at day 10. However, if rats of the same strain had been orchiectomized at 10 days of age, neither CL nor luteinizing follicles were found at 35 days. In those S-D animals orchiectomized and given ovarian transplants at 10-115 days of age, luteinization was frequently encountered in the grafts 40 days later. In Wistar rats which had been orcheictomized and given ovarian transplants immediately afterward, luteinization was less frequent in the grafts after residence for 40 days in the hosts than in similar grafts in S-D rats. If Wistar rats were operated at 135 days of age, most of the ovarian grafts contained follicles but no CL. By contrast, CL were never formed in ovarian grafts in Wayne rats 40 days after orchiectomy and ovarian transplantation performed at 65 days of age. These findings indicate that luteinization may occur occasionally in subcutaneous ovarian grafts in orchiectomized rats and there are differences in incidence of luteinization according to strain and age of the hosts.
