Infertility primarily refers to the biological inability of a person to contribute to conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term.
Researchers led by Kyushu University have succeeded in using mouse stem cells to reconstruct structures in the ovarian environment critical for the generation of mature egg cells.
MIT engineers, in collaboration with scientists at Cancer Research UK Manchester Institute, have developed a new way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells.
Mammalian sperm cannot fertilize an egg from the get-go. It's an ability acquired only after insemination, during passage through the female reproductive tract, and requires two consecutive, time-sensitive processes to provide sperm with the physical and biochemical traits necessary to complete their fundamental job.
Throughout development, life and the processes of aging, all human cells accumulate mutations, resulting in what is called mosaicism, a condition in which different cells in the same person have different DNA sequences or genetic makeup.
Scientists have come up with a method that enables the use of multi-focal images to reconstruct the movement of fast biological processes in 3D.
A team of Oxford researchers successfully identified hundreds of genetic markers that are involved in two of life’s most momentous milestones.
An herbicide extensively used in forestry, agriculture, and other applications can significantly impact the reproductive health of a common perennial plant.
Inside the nuclei of cells, the genome is tightly organized (packaged). This three-dimensional (3D) genome organization is basic because it controls gene expression.
Pioneering research led by experts from the University of Exeter's Living Systems Institute has provided new insight into formation of the human embryo.
Researchers have developed a novel approach that has resulted in the discovery of a natural compound that acts as a male contraceptive agent.
A Brazilian study published in the journal Molecular Human Reproduction helps understand why obese mothers tend to have children with a propensity to develop the metabolic disease during their lifetime, as suggested by previous research.
Now, a new study has shown that there are high levels of microplastics in the human diet and that drinking water is a significant source.
Plastics contain and leach hazardous chemicals, including endocrine-disrupting chemicals (EDCs) that threaten human health.
A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the way.
Michigan State University researchers have identified a potential genetic target for treating an especially painful and invasive form of endometriosis.
According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame.
The exchange of DNA between chromosomes during the early formation of sperm and egg cells normally is limited to assure fertility.
The female reproductive tract has the final say in human mate choice, according to new research from the University of Eastern Finland.
It can be hard to dispute the common adage 'survival of the fittest'. After all, "most of the genes in the genome are there because they're doing something good," says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research
Using state-of-the-art 3D microscopy and mathematics, Dr Hermes Gadêlha from the University of Bristol, Dr Gabriel Corkidi and Dr Alberto Darszon from the Universidad Nacional Autonoma de Mexico, have reconstructed the movement of the sperm tail in 3D with high-precision.
