A woman’s bone marrow may determine her ability to start and sustain a pregnancy, report Yale researchers in PLOS Biology. The study shows that when an egg is fertilized, stem cells leave the bone marrow and travel via the bloodstream to the uterus, where they help transform the uterine lining for implantation.
Can a woman get another woman pregnant with bone marrow?
If a woman chose to do so, speculated tabloid journalists, she could make sperm from her own bone marrow, fertilize another woman’s egg — and voila! “Men could be completely sidelined,” according to Britain’s Daily Mail.
Can sperm be made from female bone marrow?
Nayernia says that researchers have produced the same early-stage sperm cells in mice from bone marrow cells taken from female mice. “It should be perfectly possible for fully functional mature sperm cells to be made from these female-derived cells too,” he told New Scientist.
Can 2 girls have a baby?
The short answer to this question is no, not through sexual intercourse. Two cisgender women (meaning assigned female at birth) in a relationship cannot become pregnant without some form of assisted reproductive technology (ART).

Can a man get pregnant?
Yes, it’s possible for men to become pregnant and give birth to children of their own. In fact, it’s probably a lot more common than you might think.
Can a baby be made without sperm?
There are no good scientific or medical reasons to make human babies from artificial embryos made without sperm or eggs, says Nicolas Rivron at the Institute of Molecular Biotechnology in Vienna, Austria.
Is it healthy to eat sperm?
For the most part, yes, the components that make up semen are safe to ingest. Swallowed semen is digested in the same way as food. However, in very rare circumstances, some people might discover that they’re allergic to semen. This is also known as human seminal plasma hypersensitivity (HSP).

Is there sperm in bone marrow?
Summary: Adult stem cells extracted from human bone marrow have been coaxed into becoming male reproductive cells. Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created.
