Similarly, blastocysts that exhibited an A-grade TE yielded a significantly higher clinical pregnancy
and live-birth rate than those that exhibited a C-grade TE (62.4% vs.
, who demonstrated an advantage of operative laparoscopy (excision or ablation of endometriosis lesions) rather than diagnostic laparoscopy in terms of clinical pregnancy
rates, with an OR of 1.66 (95% CI, 1.09-2.5 I) in infertile women with mild endometriosis.
In our study the high circulatory levels of Leptin in clinical pregnancy
in comparison to non-pregnant group, has been observed by previous researchers where circulatory levels were related to repeated spontaneous abortions and higher levels with superior implantation success rates.21,22
In conclusion, [beta]-hCG levels 12 days after ET have value for the prediction of clinical pregnancy
, but not for ongoing pregnancy.
We used the model of IVF to investigate human reproduction and early pregnancy outcomes, ranging chronologically from oocyte retrieval, oocyte fertilization, embryo quality, and implantation to clinical pregnancy
and live birth.
The treatment effect is more marked in patients that did not achieve clinical pregnancy
and therefore it may be more suitable for oocyte donors or for patients with postponed embryo transfer.
As is shown in table 4, the chemical and clinical pregnancy
rate, implantation rate, and live birth rate were high in group D, followed by group C, in comparison to the other groups; nonetheless, the difference was not statistically significant.
Significantly higher implantation and clinical pregnancy
rates were observed in their GCSF group compared to control group (31.5% versus 13.9% and 48.1% versus 25%, resp.).
The authors also noted a significantly higher clinical pregnancy
rate with the combination of recombinant gonadotropins versus r-hFSH alone (RR: 1.30; 95% CI: 1.01 to 1.67; ITT population).
 stated that clinical pregnancy
and live birth rates were lower, whereas miscarriage rates were higher in women with BMI [greater than or equal to] 25 kg/[m.sup.2] undergoing IVF/intracytoplasmic sperm injection (ICSI).
