Fertility

A global study tracking birth data from 165 countries has found more twins are being born than ever before. The study reveals twinning rates rose by a third over the past 40 years but the researchers suggest this trend may have reached a natural peak.

A new breakthrough could lead to a safe, effective and reversible male contraceptive pill, as a compound from traditional Chinese medicine has been shown in tests to render mice and monkeys temporarily infertile.

A proof-of-concept study is suggesting epigenetic biomarkers in a father's sperm can predict how susceptible their offspring will be to developing ASD. The research is still in preliminary stages requiring further investigation in larger cohorts.

Researchers have developed a way to treat male infertility by delivering nanoparticles loaded with proteins directly into the testes. In tests in mice, previously infertile animals were soon able to father pups at a similar rate as unaffected mice.

In a breakthrough that promises to revolutionize the precision breeding of animals, scientists have used the CRISPR gene editing tool to produce infertile animals that become "surrogate sires" and produce sperm containing only donor animal DNA

New research suggests a person’s lifespan could be predicted at a young age by measuring the volume of genetic mutations they accumulate, raising the prospect of developing medical interventions so people could live and stay healthy much longer.

A genetic variant inherited from our ancient Neanderthal relatives and thought to confer heightened fertility has been found in modern humans. The new research suggests almost one in three European women carry some degree of the gene variant.

Couples trying to conceive often feel like they're racing the clock, as the quality and number of eggs declines in women. Now, this egg aging process has been reversed in mice using a metabolic compound, possibly leading to new fertility drugs.

An observational study has linked fish oil supplements with improved semen quality and testicular function in healthy men. The research can't prove causation, however, it does echo research reaching similar conclusions in men with fertility issues.

Scientists have determined that lycopene, which is a pigment that naturally occurs in tomatoes, greatly improves sperm quality.

Scientists are trying to save the northern white rhino from extinction, using artificial insemination.

Identifying one's fertility window is critical for many women trying to get pregnant – and those wanting to avoid it – but it can be a difficult, inaccurate process. Yono, an earbud-like device takes the data collection and analysis off your hands, while adding significant improvements in accuracy.
