Scientists have created a synthetic embryo without sperm or egg which could help people getting pregnant in the future.
Researchers used stem cells to create a mouse embryo in a dish which came after over 10 years of research.
Stem cells are special cells produced by bone marrow – a spongy tissue found in the centre of some bones – that can turn into different types of blood cells. A stem cell or bone marrow transplant replaces damaged blood cells with healthy ones. It can be used to treat conditions affecting the blood cells, such as leukaemia and lymphoma.
Lead study author Magdalena Zernicka-Goetz said: “Our mouse embryo model not only develops a brain, but also a beating heart, all the components that go on to make up the body.
“It’s just unbelievable that we’ve got this far. This has been the dream of our community for years, and a major focus of our work for a decade, and finally we’ve done it.”
How did scientists create a synthetic embryo?
According to the study, a natural embryo needs three types of stem cells to form: one become the placenta that connects the woman to the foetus, another the sac where the embryo develops and the third one becomes the body tissue.
Researchers isolated the three types of stem cells from the embryos and place them in a container to bring the cells together and to encourage them to crosstalk between them.
Zernicka-Goetz said that, as time passed, researchers were able to see a more complex structure.
However, there is a difference in complexity between human and mouse embryos which could take further years of research.
How we can address the gender imbalance in fertility testing
Everyone has heard of the female biological clock, but not many people know that male fertility declines throughout adulthood too
Although one in six couples globally have difficulty conceiving, infertility remains a woman’s social burden. We need to address male infertility, says Lily Elsner.
Infertility affects 186 million people worldwide and, despite everything society has led us to believe, one-third of infertility cases are caused by male reproductive issues.
Male infertility can be caused by low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Some men may also experience fertility issues due to chronic health problems, illnesses and lifestyle choices.
How come no one talks about it? To date, fertility has been firmly cast as a “woman’s issue”, irrespective of men being half of the fertility equation.
Everyone has heard of the female biological clock, but not many people realise that male fertility declines throughout adulthood too. Research shows that men will generally see a 52 per cent decrease in fertility rate between their early 30s and their mid-to-late 30s.
“Male infertility, although often treatable, is a very taboo subject,” says Lily Elsner, co-founder and CEO of Jack Fertility.
“Because men don’t have the same relationship with their physicians as women do, they often don’t know they could do something about it.”
Culturally, it can also be hard for men to talk about having trouble conceiving as this can be seen as a lack of masculinity.
Research shows that the majority of men (73 per cent) are unlikely to talk about their infertility with others. In fact, 39 per cent are not likely to talk about their infertility at all.
Elsner, however, thinks we can change that. As the woman behind Jack Fertility’s at-home sperm test kit, she thinks talking openly about male infertility could go a long way towards addressing the gender imbalance in fertility testing.
“The whole point of femtech is to ensure women’s health is prioritised. By opening up the conversation around reproductive health and making it easy to assess male fertility, we can take some of the pressure off of women.
“Some men may not want to talk about their infertility still, but it’s an essential component of creating an equal world for all genders. I am tired of watching women shoulder the majority of infertility’s physical and emotional burden, and seeing men and non traditional families completely neglected in the medical and societal discourse surrounding fertility.”
A test like Jack, Elsner says, could give people that empowerment of having access to their health data and provide them with the tools to be able to make the right decision for them.
“A lot of men think of fertility as static, when really the male body is constantly creating sperm. With Jack, what we are trying to say is, ‘Actually, your fertility massively depends on your current health and chronic illnesses’.
“Our aim is to make it easy and convenient for all men to get reliable results about the status of their fertility, even if they are not considering starting a family. That’s part of why we named the company Jack – it’s cheeky and relatable.”
There are many fertility test on the market, but Elsner doesn’t see that as a bad thing.
“The rise of companies providing at-home sperm testing suggests a growing interest in male reproductive health, but it also signals a shift in attitudes, with fertility being recognised as an issue that affects both men and women equally,” she says.
“There are so many amazing companies out there working on fertility tests, but I think most of them are targeted a little bit further down the funnel. For us, it’s about getting men to take that first important step of getting tested. We just want them to have a chat with Jack.”
Jack Fertility is expected to launch later this year. To find out more, visit jackfertility.co.uk.
Partnership to pilot ‘cutting-edge’ embryo selection tool
The partnership is hoped to streamline laboratory operations with the potential future benefit of optimising the embryo selection process
The US fertility technology company Alife Health has teamed up with a network of laboratories to pilot an AI technology for embryo image capture and cataloguing.
The company’s partnership with Ovation Fertility aims to focus on streamlining laboratory operations with the potential future benefit of optimising the embryo selection process.
The technology could enable future “AI-powered” embryo selection.
Alife’s Embryo Assist software promises to help embryologists to create digital records of every embryo, with the added benefit of using the start-up’s clinical decision support algorithm to determine the best embryo for transfer.
Paxton Maeder-York, founder and CEO of Alife, said: “We are thrilled to join forces with Ovation, a leading laboratory network in the country, to showcase the transformative impact of Alife’s technology.
“Through this partnership, we aim to demonstrate how Alife’s advanced technology, powered by AI, can not only optimise clinic workflow, but also set a new standard in the precision and consistency of embryo selection.
“We look forward to contributing to Ovation’s commitment to excellence in fertility care.”
Matthew VerMilyea, vice president of scientific advancement at Ovation, added: “At Ovation, we strive to discover and leverage the most state-of-the-art technologies available to us in order to better improve patient outcomes.
“The Alife Embryo Assist software provides our laboratories with a structured digital approach to a rather manual and cumbersome process.
“I believe that by implementing Alife’s technology, we will see an improvement in lab efficiency and performance, which ultimately will help our network provide the best possible outcomes for every individual hoping to grow their family.”
The Embryo Assist software claims to allow embryologists to capture images of each embryo and streamline the embryo reporting process by eliminating the need to manually transcribe information between systems.
Alife expects the tool to “elevate” laboratory quality-control measures by providing an activity and audit trail for every embryo, viewable in real time.
