Is Cleavage Stage Multinucleation Indicative of Lower Pregnancy Potential in Euploid Blastocysts?

Fertility & Reproduction, 2022
Background: Cleavage stage multinucleation is a morphological assessment IVF labs may use to rank embryos for transfer, as blastocysts that were multinucleated at the 2-cell or 4-cell stage have a lower live birth rate (LBR) compared to blastocysts that ...

Noneffectiveness of cryostorage duration on clinical and neonatal outcomes after single vitrified-warmed blastocyst transfers

Middle East Fertility Society Journal
Background In the current era of assisted reproductive technology, the strategy of single vitrified-warmed blastocyst transfer (SVBT) is acknowledged for positively impacting clinical outcomes and preventing the risk of multiple conceptions.

Three‐Dimensional Ovary Model to Improve and Study Murine Follicle Growth

Advanced Healthcare Materials, EarlyView.
To develop new methods for fertility preservation in women, novel culture systems for small follicles need to be established. In this work, a poly(ethylene glycol) based scaffold, with appropriate mechanical and bioactive features to support mouse follicle and ovary cell growth is developed, and the formed cell‐follicle interactions are visualized ...

Association between miscarriage rates in modified natural ovulation cycles and hormone replacement cycles during frozen-thawed embryo transfer in three IVF JAPAN GROUP fertility clinics: a retrospective analysis

Middle East Fertility Society Journal
Background Optimal endometrial preparation for frozen-thawed embryo transfer (FET) remains debated owing to conflicting results regarding outcomes in modified natural ovulation cycles (NCs) versus hormone replacement cycles (HRCs). Therefore, we aimed to

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Reduced live birth rates in frozen versus fresh single cleavage stage embryo transfer cycles: A cross -sectional study

International Journal of Reproductive BioMedicine, 2020
Background: Studies have suggested that embryo-endometrial developmental asynchrony caused by slow-growing embryos can be corrected by freezing the embryo and transferring it back in a subsequent cycle.

The effect of early administration of rectal progesterone in IVF/ICSI twin pregnancies on the preterm birth rate: a randomized trial

BMC Pregnancy and Childbirth, 2020
Background The rate of multiple pregnancies in IVF/ICSI ranges from 20 to 30%. The incidence of preterm birth in multiple pregnancies is as high as 60% and is even higher in pregnancies conceived after IVF & ICSI. The effect of progesterone on prevention
