sexual desire boosted by breastfeeding odours - chemical absorbent pads
The researchers found that Alison mokluk believes that women's sexual desire is stimulated by the smell emitted by breast-fed women and newborns.
This finding adds to the growing evidence that our natural scents affect others at an unconscious level, and reinforces the argument that the human information element exists and still has a subtle effect on us.
In this study, scents associated with breastfeeding increased the sexual intimacy of childless female volunteers.
Why this is a mystery, but the researchers believe that this may be a way for women to signal to each other that the environment is a good breeding environment.
Julie Mennella of the Monell Chemical Sensory center in Philadelphia and a team at the University of Chicago asked 26 nursing mothers to wear water suction pads under their bras and underarms.
The smell collected on the mat may come from the mother and the feeding baby.
Another 45 women who had never given birth received a "sniff challenge" over the next three months ".
For a month, all women sniffed control pads with phosphate buffer four times a day.
During the last two months, some women were randomly selected to sniff pads with a compound that was breast-fed, while others continued to use a controlled scent pad.
The volunteers measured their body temperature every day, collected urine samples and recorded their sexual behavior.
On 2001, Mennella's team found that the smell of exposure to breastfeeding disrupted the menstrual cycle of volunteers and the colon;
The longer the cycle, the shorter the cycle.
This new study reveals a more subtle effect.
While women who smell breastfeeding compounds do not report an increase in sexual behavior-which is most notably affected by the absence or presence of a partner-they do report a significant increase in sexual desire and a more persistent fantasy.
"The data is amazing," said Mennella, who presented her evidence this week at a meeting of the chemical reaction Science Association in Sarasota, Florida.
She concluded that these chemicals, which encourage other women to reproduce, may have evolved into a signal that the environment is appropriate for raising young people.
In many cultures, new
We encourage married young women to spend their time with new mothers to increase their chances of having children, she said.
"I want to know if these cultures are digging something.
"She is keen to know if the smell of breastfeeding has any effect on fertility.
Richard Brown, a psychologist at Dalhousie University in Halifax, Nova Scotia, notes that these are only preliminary findings.
But he noted that progesterone levels in breast-fed women were higher than normal.
"Maybe the effect of high progesterone is like a male hormone," he speculated . "
"Maybe that's the weirdest thing they're producing men --like odours.
