Salivary oestradiol (E2) and progesterone (P) levels have been shown to reflect the biologically active fractions in the serum. The luteal-phase status of stimulated cycles was investigated after in vitro fertilization and embryo transfer (IVF-ET). Thirty patients were randomly allocated to one of three luteal therapy groups: group A had no support, group B had intramuscular P and group C had intramuscular P and human chorionic gonadotrophin (hCG). One pregnancy was achieved in group A, two in group B and three in group C. Significant correlations between salivary and serum levels of E2 and of P in matched samples during luteal phase were found. Salivary E2 levels from luteal day 8 through day 14 and P levels from day 3 through day 14 were significantly higher in the pregnant than in the nonpregnant cycles. Among the nonpregnant cycles, salivary E2 and P levels were significantly higher in group C than in group A or B. These findings suggest that, in stimulated cycles for IVF-ET, determination of salivary E2 and P levels may be used as reliable alternatives to serum concentrations for assessing the luteal phase. Also, the additional hCG has an enhanced luteotrophic effect, as reflected by the higher salivary E2 and P levels, which may lead to a better pregnancy rate.

Abstract Background: In this study, we compared the in vitro embryo development, embryo transfer outcome and the offspring outcome in the in vitro fertilization-embryo transfer (IVF-ET) between dry culture (DC) and humid culture (HC). Methods: Our study was divided into two parts. Firstly, we determined the fertilization rate, cleavage rate and high-quality embryo rate from 21 cycles in the DC group (N=262 oocytes) and HC group (N=263 oocytes). Secondly, we determined the embryo transfer outcome and the offspring outcome in DC group (N=184 cycles) and HC group (N=136 cycles). Results: Compared with the HC group, significant increase was observed in the high-quality embryo rate (66.1.2% vs. 55.3%, p=0.037) and implantation rate (49.8% vs. 40.6%, p=0.027) in the DC group. No statistical differences were observed in the pregnant outcome and birth defect of the offspring (p>0.05). Compared with HC, DC was associated with a higher high-quality embryo rate and a higher implantation rate after embryo transfer. Conclusions: No statistical differences were noticed in the offspring conditions between the two culture modes. Taken together, DC may serve as a promising method for IVF-ET.
