dc.description.abstractThis study aimed first to evaluate the effect of recombinant human FSH (rhFSH) with and without recombinant human LH (rhLH) on fresh and frozen-thawed embryo development and also to analyze the immune response of rabbit does (Oryctolagus cuniculus) subjected to repeated rhFSH treatments. Nulliparous New Zealand White does were used. In Experiment 1, 120 does were superovulated with 25 IU rhFSH alone or in combination with 5% or 10% rhLH (1.25 IU or 2.50 IU rhLH). A total of 1116 embryos at the compacted morula stage were cultured at 38.5 T, 5% CO(2), and saturated humidity for 48 It. The embryo development to hatching blastocyst was significantly lower for the group with 10% rhLH versus that of the control group (65.6 vs. 79.5 for rhFSH + 10% rhLH vs. control, respectively). However, no significant difference was found in development to hatching blastocyst for the control, rhFSH alone, and rhFSH + 5% rhLH groups. The developmental potential of frozen-thawed embryos obtained from all groups was similar, with an 83.5% in vitro development rate until the expanded blastocyst stage. To detect anti-FSH antibodies, in Experiment 2, does were subject to four superovulation treatments. The hormone administration had a significant effect on immune response in the superovulation group after two treatments (0.14 +/- 0.074 and 0.15 +/- 0.076 vs. 0.46 +/- 0.078 and 0.50 +/- 0.078 optical density for the first, second, third, and forth cycles, respectively). Nevertheless, none of the treated does had an immune response in both the first and second treatments; on the contrary, a significant increase in the antibody levels was observed in these females at the moment of the third and fourth superovulation treatments. In conclusion, rhFSH superovulation treatments increase the reproductive potential of rabbit does. (C) 2009 Elsevier Inc. All rights reserved.
