Sexual competition has made sperm the most diverse - and fascinating - cells in the animal kingdom.
Is a woman’s longing for a child evolution at work, or social conditioning? And what about those who don’t want kids? Are they defying nature? Probably not, as almost everyone wants sex.
Many animals, including humans, form long-term partnerships, but some are same-sex, suggesting they’re not all about raising offspring but some other form of cooperation.
Scientists have tended to think of nonhuman sexual behaviour as being all about reproduction. In fact, there is far more ha ha hee hee than we give animals credit for.
Since science made it possible to research manipulating the cells that are linked to reproduction, the naysayers have carried the day. But how solid are their objections really?
I sometimes forget that people can feel embarrassed listening to me talk about my research on sperm. But often those same people can also be a source of amazement and inspiration.
Recent research into the health effects of the plastic-making chemicals phthalates has reignited concerns about low sperm counts. But the evidence is far from conclusive.
Sperm banks and human cloning may not be the future. A study in beetles reveals that having two sexes boosts genetic quality.
A sterilisation camp held in Chhattisgarh, an impoverished state in central India, has claimed the lives of 13 women, most of whom were young and marginalised. The women, who died within hours of the procedure…
Mice possess a notable talent: they are excellent at making more mice. Their ability to reproduce at a breakneck pace is one reason they are often used as experimental research subjects. Thus, when Dr…
Honeybee reproductive cycles begin when the colony grows to a certain size. Cornell University researchers found honeybee…
The UK parliament will soon consider making Britain the first country to allow three-person IVF. The regulations are yet to be approved, but the government is currently backing moves to allow the creation…
Light pollution disrupts the natural reproductive cycle of lemurs a new study has found. Male lemurs are sexually inactive…
Sperm grown from the frozen testicle tissue of newborn mice has been used to produce healthy offspring, according to a new…
Males produce faster sperm when mated to their sisters, according to a recent study of guppies. Researchers from the University…
Males will mate with anything. Well, that is the general view, one that exists because of a simple biological underpinning: females are reproductively limited by costly gestation, while males are only…
An aroma given off by male goats activates reproductive brain regions in their female counterparts. The study is the first…
The female sex hormone oestrogen can be produced and released from the brain as well as the ovaries, according to a study. The research, recently published in the Journal of Neuroscience, shows that the…
Imagine if you only had one shot at passing on your genes before you died. It happens more often in the natural world than you might expect: suicidal reproduction - where one or both sexes of a species…
