Summary: The study found that using the afterload technique for embryo transfer can reduce the rate of difficult transfers, with significant variation observed among operators. However, there was no significant difference in clinical pregnancy rates between the two techniques.

Summary: This study investigates the impact of buffalo uterine epithelial cells and their conditioned medium on in vitro embryo production. The results show that co-culture of embryos with steroid treated UECs and their CM improves blastocyst and hatching rate.

Summary: sHLA-G secretion by the embryo is associated with implantation and live birth, and its concentration depends on the ovarian stimulation protocol used.

Summary: The study compared two types of corpus luteum in cattle, finding that the cavitary corpus luteum (CLcav) had larger size, higher serum progesterone concentrations, and better final pregnancy rates in recipient heifers after embryo transfer (ET) compared to the homogeneous corpus luteum (CLhom).

Summary: The study found that the duration of embryo vitrification did not significantly affect pregnancy outcomes within 5 years, but a significant decrease in clinical pregnancy rate and live birth rate was observed after more than 5 years of storage. Postponed embryo transfer was associated with increased risks of large for gestational age and placenta previa. It is important to note that the conclusions were drawn from a small sample study after propensity score matching, and caution should be taken in interpreting the results.

Summary: This study investigates the impact of embryologist and physician on the outcome of embryo transfer, finding that both factors significantly affect the ongoing pregnancy rate (OPR), with physicians having a slightly greater contribution. The experience of embryologists does not have a significant association with the outcome.

Summary: The study compared the effects of hyaluronic acid (HA)-enriched transfer medium versus standard medium on live birth rate after frozen embryo transfer (FET). The results showed that the use of HA-enriched transfer medium did not improve the live birth rate of FET compared with standard medium.

Summary: This study focuses on how nanoparticle shape affects mixed convective flow along a vertical impermeable wall in a non-Darcy porous medium. Results show that blade-shaped nanoparticles have higher velocity than brick-shaped nanoparticles. Additionally, a comparison of heat transfer in Darcy and non-Darcy flows for different volume fractions was conducted.

Summary: This study found that culture media can impact the developmental kinetics of preimplantation embryos and affect the classification within the KIDScore algorithm, but there were no differences in pregnancy outcomes between the groups.

Summary: The domestic buffalo, also known as water buffalo, is a globally significant livestock species. It includes two sub-species, the River buffalo and the Swamp buffalo. The River buffalo is a primary source of milk and meat in South Asia and supports high-value food production in Europe and the Americas. The Swamp buffalo is important for draft work and food in Southeast Asia and East Asia. The use of assisted reproduction, such as artificial insemination and embryo technologies, is becoming increasingly important for genetic improvement in buffaloes.

Summary: The study suggests that embryo vitrification significantly affects placental histopathology pattern and may lead to a higher prevalence of dysfunctional labor in singleton live births.

Summary: A systematic review and meta-analysis found that the stage of embryo transfer had a significant impact on obstetric and perinatal outcomes in programmed frozen-thawed embryo transfer (FET) and natural FET cycles. Programmed FET cycles had higher risks of hypertensive disorders of pregnancy, gestational hypertension, preeclampsia, gestational diabetes mellitus, large for gestational age, macrosomia, preterm delivery, placenta previa, postpartum haemorrhage, and preterm premature rupture of membranes compared to natural FET cycles with overall embryo transfer and blastocyst transfer. However, there were no clear differences in outcomes between programmed FET cycles and natural FET cycles with cleavage-stage embryo transfer.

Summary: Serum LH levels have an impact on the live birth rate during ovarian stimulation cycles and after embryo transfers, with low LH levels associated with a decreased live birth rate after fresh embryo transfers.

Summary: The multivariate analysis suggests that midluteal progesterone level seems to impact live birth rates more than preovulatory progesterone level in women undergoing IVF treatment followed by fresh embryo transfer.
