18 wrz 2023 · Further illustrating this point, a 2022 study found that the clinical pregnancy rate for women under 30 who’d undergone an embryo transfer was 69.4%, whereas for women ages 40 to 43, that figure...
4 lis 2022 · Ongoing pregnancy or live birth rate after euploid embryo transfer comparing women <35 years old vs. women ≥35 years old was our primary outcome. Secondary outcomes included the evaluation of IR and MR in women <35 years old compared with women ≥35 years old.
1 maj 2024 · Hughes et al. (3) reported the highest chance of LB in women aged between 26 and 30 years, with a steady decline from the age of 34 years. A similar association was noted in a study by Jones et al. (17), with the best chance of LB in women aged 30 years and a sharp decline from the age of 35 years.
12 lis 2021 · The under 35-year age group showed the smallest difference in success rate of PGT-A vs non-PGT-A. That is, 2.6 and 3.3 embryos transferred respectively for each live birth and the > 44 years showed the greatest difference in success rate of PGT-A vs non-PGT-A, where 3.1 and 35.0 embryos transferred respectively for each live birth.
Evaluating embryo quality has been consistently linked with implantation, clinical pregnancy rates, and LBs (64, 65). In cases where preimplantation genetic testing is not conducted, embryos are commonly selected for transfer on the basis of their quality.
A recent review found that ultrasound-guided embryo transfer was associated with improved clinical pregnancy rate (OR 1.31, 1.17–1.45; 20 trials; N=6,711 women) and live-birth rate/ ongoing pregnancy rate (OR 1.47, 1.30–1.65; 13 trials; N=5,859 women), compared with clinical touch (Fig. 2) (48).
7 paź 2024 · Extending embryo development to 5–6 days via blastocyst culture enhances embryo selection and uterine synchronization, which boosts implantation rates . Vitrification, a rapid cryopreservation method, prevents ice crystal formation, resulting in higher success rates for frozen embryo transfers (FET) . These innovations have led to the ...
