Ugly men produce fitter babies

Good news. Ugly fathers produce fitter babies.

Women, take note – that Adonis you’re eyeing up as the father of your unborn child is the wrong choice.

Instead, pick an ugly man – as he will produce healthier babies than an attractive one, research suggests.

The theory centres on females knowing they may not have another chance to procreate, so they decide to make the best of what they have – an unattractive male.

Offspring from ‘low-quality’ males need extra resources to flourish so females compensate by investing more in the reproduction, scientists claim.

The discovery came after monogamous female zebra finches which paired with the least attractive males laid larger eggs with more orange yolks – a sign of good health.

‘Females also deposited more testosterone into eggs when paired to a low-quality male,’ said German bird ­expert Elisabeth Bolund, whose findings were published by the Royal Society.

Sperm increases housework

Fantastic discovery today for all us put upon men - sperm makes females do more housework.

While the exhausted male takes it easy and has a doze, a chemical in sperm spurs females into an intense period of domestic activity.

Such is the effect on the female, it can see them cleaning and tidying for up to ten days.

But here’s the catch the discovery was in fruit flies!

Fly sperm is coated with a ’sex peptide’ which prompts the period of domestic activity in females.

A better understanding of how chemicals affect sleep patterns could shed light on neurological disorders such as narcolepsy, said Prof Elwyn Isaac from the University of Leeds, England.

Fruit flies are supposedly a good model for looking at human sleep behaviour as they share many traits with us. ‘It’s well documented that  coaches advise their teams to practise celibacy before an important match,’ said Prof Isaac.

‘Mating made the male flies very lazy and they took a long siesta period afterwards. But the females became much more active and busy,’ he added.

‘They also developed a much more adventurous lifestyle than virgin females, flying around to forage, find nesting sites and perform domestic-type duties.’

He added that the chemical makes female flies form an attachment to their mate and reject other males.

‘Once the female has mated, if a different male performs a courtship ritual and tries to mount her she will kick him away,’ he added.

‘The chemical makes her reject all other suitors.’
