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.
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.
Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.
The Y chromosome, which is relatively smaller than its counterpart, the X chromosome, has significantly reduced in size across 200 million years of evolution.
One in fifty births in Japan are said to be through in vitro fertilization, and many couples remain unable to conceive for reasons unknown. Infertility is also an undesired side-effect of lifesaving cancer treatment in childhood.
Researchers from the University of Cambridge have devised a new model to analyze an early stage of human development through human embryonic stem cells.
The gene C19ORF57 has been identified to play a major role in meiosis by the Institute of Molecular Embryology and Genetics at Kumamoto University.
Researchers analyzed 13,000 tumors, highlighting two formerly overlooked genes as promising new therapeutic targets for treating cancer.
Over the last six years, a group of geneticists has studied genes associated primarily with female hormone synthesis and ovarian follicle development.
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.
