Stable-Family-and-Low-Body-Weight-Mean-Later-Sex-for-GirlsYou may say that, in a stable family, children are less exposed to sex imagery and these more protected girls are less prone to early sex. But a new research, published in “Child Development”, shows they really turn later from little girls into little women. The research team at the University of Arizona and the University of Wisconsin, Madison, shows that girls growing up with supportive family experience have a delayed puberty onset.

Early puberty has been connected by various researches to mood disorders, substance abuse, adolescent pregnancy and increased risk of reproductive system cancers. Knowing these risks means early intervention and improved prevention strategies. Read more

Too-Much-Sugar-Finishes-Off-Your-Sex-LifeCould you imagine your life without pumping every day countless amounts of sugar in your body? If not, you should at least know that it can affect your sexuality: high levels of fructose and glucose entering your blood can deactivate the gene controlling the amounts of sex hormones in both men and women, as revealed by a Canadian research published in the Journal of Clinical Investigation.

The research made on mice and human cell cultures warns that we should replace simple sugars (like table sugar, glucose and fructose) with complex ones, like starches. Table sugar is a dimer made of glucose and fructose (and as glucose and fructose it enters the blood), while fructose abounds in sweetened beverages, syrups, and many other products. In North America, the annual average intake per person is of 33 kg (74 pounds) of table sugar and 20 kg (45 pounds) of fructose corn syrup. Read more

Why Are Women More Prone to Addictions?

Why-Women-Are-More-Prone-to-AddictionsWe know that testosterone makes men aggressive and muscular, while female hormones turn women into protecting “mothers” but also more vulnerable to addictions. But a new Yale research shows that it’s not all about hormones; genes too are involved in shaping the sex-related behavior and the females’ proneness to addiction could be linked to genes located in the sex chromosomes.

“This is the first time that any behavior has been associated specifically with sex chromosomes independent of gonadal hormones,” the lead author Jennifer Quinn of Yale University told AFP.

Female mammals (including women) are known for long to be more likely than males to get habit-forming behavior, including addiction. Sex-specific hormones, secreted by gonads, explain just partially the difference. Read more

Why-Married-Men-Have-Lower-Sex-DriveDon’t blame it on the age, it’s marriage the one that makes a man less…male. Married/father males have been found to have significantly lower testosterone levels, as found by two new studies made at the University of Nevada, Las Vegas (UNLV), and led by anthropology professor Peter Gray. These researches are amongst the first carried outside North America, and studying facts from a cross-cultural perspective.

“As the scientific community begins to understand more about the biology of man, the better able we are to examine other psychological and behavioral outcomes, including the elevated risk of postpartum depression among men and the potential negative effects of testosterone supplementation on paternal investment and care”, said Gray.
