In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after ...

Children born after the use of frozen embryo transfer were at higher risk of childhood cancer, according to a new study, but the risk remains low. Children born after the use of frozen embryo transfer ...

An international team of scientists has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape.

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Sharing the motivation behind their study, Prof. Yamagata explains, "Although the influence of ovarian stimulation on embryo quality has been described, this issue remains controversial. Here, we ...

Oct 24 (Reuters) - Transferring one embryo into women during in vitro fertilization (IVF) doesn't lower their chances of giving birth but it does mean fewer women give birth to twins, with all the ...

The schematic outlines the development and validation of an AI model for evaluating in vitro-fertilized human embryos. It utilizes images captured at specific time points post-insemination (Day 1 and ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

NEW YORK (Reuters Health) - Many couples who undergo infertility treatment might donate their extra embryos to stem cell research, if they fully understand all their options, a new study suggests.
