Why do womens' extent match? Why do men carry pregnant?

When I worked in an bureau with women, pretty soon we be all on impossible to tell apart period diary. What actually CAUSES that? Is it lunar? Psychological? Also, I've see two men get really strong "sympathy pregnancy" symptoms (Couvade Syndrome" - but nothing I read really explains WHY. WHY on land and how do these things happen? Is it psychological? Is it hormonal? Thanks!

This phenomenon can be observed almost everywhere that two or more women live or work together in close camp {for example, college dorms, boarding schools, office, or sisters living together in the same house}. Some studies suggest that humans of both sexes veil some undetectable chemicals called pheromones, and that's what cause women who are close to each other for prolonged lapse of time to develop this "synchronicity" in their menstrual period. Personally, I know of a case of a jewelry store contained by which all the staff member were females {6 surrounded by total}; first they started to menstruate at about like time of the month. Then, 3 of them got pregnant on one and the same month, the other 2 got pregnant the subsequent month, and the female organizer {who had be trying unsuccessfully to conceive for 14 years} got pregnant the following month, in need any kind of treatment. So within the case of women, the result in could very resourcefully be hormonal. As for men, it's been found that they find women more attractive by midcycle {when feminine fertility is at its peak}; this could be the result of a greater amount of pheromones secreted by women at this time of the month. This could also explain why some of them {specially a pregnant woman's husband or boyfriend, but most often a woman's masculine twin brother} experience pregnancy-like symptoms such as morning sickness, and in some cases even "labor pains".

It's been said that synchronized menstruation is due to pheromones from the alpha females. There is a biological source for it that no longer applies.

For your second question, you know immaculately well that men don't attain pregnant.

As far as Couvade syndrome, it may be a deep-seated yearning (that stems from envy) to be able to produce enthusiasm as women can. It isn't an everyday phenomenon.

Menstrual Cycle Synchronization Might Be Reality (October 8, 2002)

Close female friends share everything from clothing to secret, and recent studies show they might even share menstrual patterns.

While at hand is no evidence conclusive enough to prove the proposition, some scientists believe that women who live in close station or who spend a lot of time together develop menstrual synchrony, which channel they tend to menstruate around the same time of the month.

Study origin

For frequent years, this was considered by abundant women to be nothing more than an behind the times wives' tale.

But within 1968, Martha McClintock, an undergraduate student at Wellesley College, noticed that women contained by her dorm were menstruating at equal time and began to conduct studies to find out why.

She interviewed various of the women and then gather and compared data roughly their menstrual cycles, eventually publishing her findings and becoming the pioneer of menstrual synchrony research, Penn State physician Robert Heinbach said.

Controversy

Today the issue is still being studied, and researchers are debating whether or not menstrual synchrony is an actual phenomenon.

"It is incredibly controversial," Sharon Shriver, assistant professor of biology, said.

"There are obedient points on both sides [of the argument]."

Studies done within olden times couple of years have yield results supporting McClintock's case that menstrual synchrony does exist.

In one such study, researchers observed the menstrual pattern of a group of women who were brought to live together for the study, Nancy Williams, assistant professor of kinesiology, said.

After several months of living in close garrison, the women's menstrual cycles were compared again.

"[The researchers] found that 30 percent of the women have started to cycle with respectively other within three months," Williams said.

Occurrence

Studies by Leonard and Aron Weller found that menstrual synchrony occur between co-workers and between women in some closely knit people units.

Other studies found a greater point of menstrual synchrony among women who were close friends than among women who did not enjoy close relationships, she said.

Yet another study examined a group of lifeguards over an entire summer and found that by the end of the summer, nearly adjectives of the women were menstruating around indistinguishable time, Heinbach said.

However, a study that examined a women's basketball team for an extended time of time found no correlation between the women's menstrual patterns.

They in consequence also found no evidence of any occurrence of menstrual synchrony, he said.

Other factors

But Williams pointed out that exercise, dieting and stress can respectively cause change in women's menstrual pattern as well.

"[Menstrual synchrony] is not other observed, but I definitely have a sneaking suspicion that it is a real phenomenon," she said.

Many women living in dorms and apartments, especially those who share their spaces beside female roommates, agree.

"I conjecture it exists, and I just took it to be a certainty before I even know there be so many studies more or less it," said Beth Golden (senior-music).

But she also pointed out that many women, especially within college, take oral contraceptives, which regulate the menstrual cycle and could be the basis why some women menstruate at the same time.

"It's sturdy to judge when at hand are other medications or chemicals within the body," she said.

Causes

The question that tons scientists are trying to answer now is: What is it that can wreak this possible menstrual synchrony?

Heinbach said most current research experiments deal beside pheromones as the main motivation of menstrual synchrony.

This is what what McClintock had originally suggested as the exact for the observed phenomenon, but had not confirmed.

Pheromones are chemical messages passed between member of a species, which are odorless but are picked up by the olfactory (sense of smell) nervous system, he said.

"There enjoy been like mad of studies done with animals and insects previously 20 years," he said.

"Fruit flies, moths, monkeys and dogs in boil have adjectives been proven to respond to pheromones."

Heinbach said pheromone research be recently extended to humans as in good health.

In one study, a group of women who were surrounded by the follicular phase (the first two weeks of the menstrual cycle before ovulation occurs) have pads placed below their arms to pick up their pheromones.

The pheromones were later applied to the upper lips of another group of women, so the "scent" would be directly below their nose.

This second group of women was examined to see if their menstrual cycles would align beside those of the women in the first group.

This would signify that pheromones could induce ovulation in women who spend time together.

Results

The experiment showed that the use of the pheromones resulted in an increased amount of Luteinizing Hormone (LH) released in the women's bodies, he said.

He explained that LH is released instinctively by the pituitary gland during the follicular phase to trigger the beginning of ovulation.

Thus, contained by effect, the study showed a correlation between pheromones and ovulation, which could indicate that pheromones are a cause of menstrual synchrony.

Williams said this hypothesis makes sense.

She described another study of a group of women who have spent time living together.

The group was divided into two smaller groups: women who be already cycling together (synchronous) and women who were not (non-synchronous).

Researchers found that, compared to the non-synchronous group, the women within the synchronous group had a sophisticated sensitivity to a certain chemical, she said.

"It shows in that is a connection between the olfactory system and the factor of the brain that controls reproductive hormones," she said.

"This has already be proven to exist in animals, which rely more on smell than humans do."

She said scientists are also trying to digit out how to measure the episode of any menstrual synchrony in women.

"We don't know how powerful it is, but it does exist," she said.
