IVF

The partners plan to investigate whether a woman’s response to ovarian stimulation during IVF treatment is linked to genomic characteristics.

The researchers said that a faster method could avoid having to freeze embryos and as a result may improve the success rate of in vitro fertilization.

At a conference last week, researchers from Italy presented results from 73 women who had mosaic embryos transferred.

According to John Zhang, founder and CEO of the New Hope Fertility Center, universal PGS will likely increase success rates of IVF further.

A study by researchers in Italy found that preimplantation genetic diagnosis and screening combined led to more successful pregnancies per transfer but fewer women had embryos transferred.

The company feels it could be an attractive target for mergers, but is also keeping an eye out for IP acquisition options of its own.

The test uses Illumina arrays to measure genome-wide sperm DNA methylation patterns in order to predict male fertility status and resulting embryo quality.

The team built on a previous approach that used single-cell sequencing to screen for chromosomal abnormalities in embryos from couples undergoing IVF.

Researchers in Saudi Arabia sequenced the exomes of women having trouble conceiving and found a mutation that appears to halt early embryonic development.
