Relationship between pregnancy rate and serum progesterone concentration in cases of porcine embryo transfer

다국어 초록 (Multilingual Abstract)

The level of P4 at the time of embryo transfer (ET) isimportant. P4 concentrations and numbers of corpora lutea for126 recipients were evaluated. Nuclear transfer embryos weretransferred into 126 surrogates. 11 maintained their pregnancyuntil full-term delivery, 17 miscarried, and implantation failedin 98 animals. P4 levels in the full-term group were significantlydifferent from those of the pigs that aborted or in whichimplantation failed (p ＜ 0.05). However, the numbers ofcorpora lutea were not significantly different. These findingsindicate that the concentration of progesterone can be animportant factor for successful ET in pigs.
