Study links a specific procedure to pregnancy complications in assisted reproduction

An experimental study from researchers in the Perelman School of Medicine at the University of Pennsylvania links a specific procedure - embryo culture - that is part of the assisted reproduction process (ART) to placental abnormalities, risk for preeclampsia, and abnormal fetal growth.

Improving IVF Treatments by Imaging Sperm Cells

News-Medical spoke to Professor Natan Shaked about his new sperm cell imaging technique that could be used to help improve the outcomes of IVF treatments.

Study hints a mechanistic link between sex and stress response in microbes

Why is sex so popular? The question of why so many organisms reproduce sexually has mystified evolutionary biologists since before Darwin, who wrote that "The whole subject is as yet hidden in darkness."

A new treatment option for activating cellular defenses against neurodegenerative disease

Talk about motherly instincts: Biologists at the University of Iowa have learned that female roundworms can alert their future offspring of dangers they will encounter when born, and the mothers pass on these warnings even before the offspring have been conceived.

Researchers develop safe, accurate 3D imaging method to improve IVF treatments

Tel Aviv University (TAU) researchers have developed a safe and accurate 3D imaging method to identify sperm cells moving at a high speed.

Study: Recombination is crucial for proper segregation of chromosomes into germs cells

From avocado plants to baker's yeast, humans to zebras, sexually reproducing organisms must create germ cells that contain half the number of chromosomes found in a typical body cell.

Study: Genes may play a far more complex role in oocyte maturation than previously assumed

Over the last six years a group of Estonian geneticists led by Associate Professor Agne Velthut-Meikas and a PhD student Ilmatar Rooda from TalTech Department of Chemistry and Biotechnology have studied genes previously associated primarily with female hormone synthesis and ovarian follicle development.

Alternative imaging technique shows promise for safer heart procedures

In the first study of its kind, Johns Hopkins researchers provide evidence that an alternative imaging technique could someday replace current methods that require potentially harmful radiation.

Novel FIMP protein may help orchestrate mammalian fertilization

Fertilization is a fundamental process in sexual reproduction when the combination of male and female gametes blends genetic material to create a new unique individual. Now, researchers from Japan have identified a new factor that may help orchestrate this vitally complex life event.

New mathematical model can help explain why so many pregnancies and IVF attempts fail

Scientists have created a mathematical model that can help explain why so many pregnancies and in vitro fertilization attempts fail.

Research suggests an avenue to treat, prevent genetic disorders in the womb

New research led by hearing scientists at Oregon Health & Science University suggests an avenue to treat and prevent intractable genetic disorders before birth.

Psychoactive ingredient in marijuana may impair ability to produce viable embryos

Female eggs exposed to THC, the psychoactive ingredient in marijuana, have an impaired ability to produce viable embryos, and are significantly less likely to result in a viable pregnancy, according to an animal study accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting.

Key protein in sperm production could aid male infertility treatments

Researchers have discovered that a key protein drives sperm production, knowledge that may help infertile couples conceive.

Targeting critical enzyme for sperm formation could help address male infertility

While some of our body's cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage known as the pachytene, when pairs of chromosomes from an individual's mother and father align and connect.

Scientists identify new role of important factor in early embryonic development

In collaboration with Stanford University, a working group from MedUni Vienna’s Division of Cell and Developmental Biology, led by Mark Wossidlo, has identified the role of a factor involved in early embryonic development.

SPRK1 enzyme plays role in reorganizing the paternal genome during fertilization

A sperm enters an egg, an embryo develops and eventually a baby is born. But back up a second -- how does the mother's half-genome actually merge with the father's half-genome to form one new human genome?

'Primitive' stem cells shown to replace and repair damaged blood vessels in the retina

Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes.

First baby born from frozen immature eggs matured in the lab

Cancer can take a toll on a woman’s body, with many unable to conceive after rigorous treatments. In some cases, especially for women who have no children yet, they opt for egg cell freezing so they can still become pregnant after treatment. Now, for the first time, a woman has given birth to a baby from frozen immature eggs harvested from her five years ago.
