Summary. Blastocysts recovered from oil- or indomethacin-treated donor rabbits between 5½ and 6 days after insemination and hCG injection were transferred to oil- or indomethacin-treated recipients between 135 and 147 h after hCG injection. Indomethacin treatment of donor rabbits (10 mg/kg s.c.) given every 6 h during the day before transfer had no effect on subsequent implantation of the blastocysts. However, indomethacin treatment of the recipients (10 mg/kg s.c. every 6 h from 120 to 168 h after hCG) prevented implantation of all transferred blastocysts, although 6 of the 8 rabbits died between Days 9 and 16 of (pseudo)pregnancy. Restriction of the indomethacin treatment of the recipients to only 3 injections of 10 mg/kg s.c. between 128 and 140 h after hCG injection had no effect on the implantation of the transferred blastocysts. It is concluded that indomethacin exerts its inhibitory influence on implantation via an action on the endometrium rather than on the blastocyst.
